    • Wireless: PRO Series
    • Is there some easy way I can use 2 microphones at the same time with my WR-PRO receiver?

      The short answer is NO. We’ve had this question asked a lot and we’ve really tried thinking of creative ways to do this using mixers, y-cables, you name it. However, if you need to record with 2 microphones at the same time, your best option is the WR32-PRO, 2-channel receiver. It will work with any two PRO transmitters simultaneously.

    • What’s the difference between VHF and UHF wireless?

      Wireless microphones use two segments of the FM radio band, known as very high frequency (VHF) and ultra-high frequency (UHF). VHF is divided into a low band starting at 49 MHz and a high band starting at 169 MHz. UHF frequencies begin at 470 MHz. The physical length of these radio waves, and limitations imposed by the FCC, account for many of the differences in how VHF and UHF wireless microphones perform.

      UHF Microphones
      UHF frequencies don't transmit as well as VHF frequencies, so the FCC allows UHF wireless devices to use more transmitting power. This gives them better range than VHF microphones. The radio waves are physically shorter, allowing UHF devices to use shorter antennas. However, they work best when there's a direct line of sight between the microphone and the receiver unit. Professional-quality UHF microphone systems can support large numbers of devices and scan thousands of frequencies to find free channels, making them a good choice for complex and variable configurations. UHF microphones also have significantly better audio quality than VHF, making them better suited to musical use.

      VHF Microphones
      VHF microphones have a few advantages of their own. They're much less costly to manufacture than UHF microphones, so they're more economical to purchase. Since they transmit at lower power, their battery life is significantly better and their operating costs are correspondingly lower. They're also less dependent on a line of sight between the microphone and receiver, so they're useful when large open areas aren't available. Low-priced VHF microphones are often built with a single fixed frequency and will be unusable if there's interference on that channel. More sophisticated models have multiple channels like their UHF counterparts.

      Assessing Your Needs
      Historically, the UHF band has been less crowded and less susceptible to interference. Although that advantage is fading, UHF microphones remain more likely to have multiple channels and be able to work well even around sources of interference. UHF is also the best choice where audio quality is important, as with onstage music. VHF is a stronger in spoken-word situations such as seminars, trade shows and presentations, where battery life and line-of-sight considerations are more important than dynamic range and audio quality. Complex situations such as a stage musical might require a combination of both UHF and VHF microphones, utilizing different frequencies.

    • Can I use my PRO Series wireless system with a PA system?

      Yes you can. Azden’s wireless microphone systems are designed for use with cameras, but the output of the wireless receiver is microphone level and can be plugged into any input for a microphone. However, in the case of hooking up to a PA system, you’ll likely have to convert the output connection from the mini-plug jack to either an XLR or ¼” TS or TRS connection. For XLR connections into a microphone level input, you may use Azden's MX-1 Mini to XLR Adapter Cable.

    • Can I use my PRO series wireless system to record into a smartphone or tablet?

      Yes. Azden’s i-Coustics® sub-brand is designed specifically for this purpose. You will be able to use any of the products labeled as "i-Coustics®" with your smartphone or tablet (see the compatibility list).

       

      You can make your current PRO system compatible with a mobile device by using the HX-Mi TRRS Mic/Headphone Cable.

    • My PRO series wireless system is not working properly. Can you repair it?

      Yes we can. See the Service And Warranty page for details. We recommend you give us a call first to see if we can troubleshoot your problem over the phone.

    • Is there any way to tell which frequency is better to use in a given location?

      PRO series transmitters and receivers all work on the same two transmission frequencies (169.445MHz and 170.245MHz). Both frequencies transmit audio equally well. The only time you might prefer to use one frequency over another is when you are getting interference. Interference can be caused by a variety of things, and could manifest as pops, static, drop outs, buzz or other noise.

      To make sure you're not getting interference on a given frequency, with the receiver and transmitter units turned on, listen to the receiver's "ear" output with either the earpiece provided or a pair of earbuds or headphones. If you can hear your subject speaking clearly then you should be good to begin recording.

      If you are hearing interference, then switch your PRO units to the other frequency. (Unfortunately, this won't be an option if you're intending on using both frequencies simultaneously with a 2 channel WR32-PRO.) If both frequencies are experiencing interference, then you may have no choice but to change your location before recording. Our VHF PRO Series wireless systems are limited in their capacity to circumvent interference issues. If you need a more reliable solution, our UHF wireless systems offer more options.

    • I’m not getting audio from my PRO receiver into my camera. What’s wrong?

      1) Double check that both batteries in each component of your PRO system are new and oriented correctly in the battery compartment.

       

      2) Make sure your transmitter and receiver are set to the same frequency (F1) or (F2) if set to the the same frequency the WR-PRO receiver's light should turn GREEN. (Note: a RED light on the WM-PRO transmitter is NOT an indication of a bad connection with the receiver. This light simply indicates that the battery is providing voltage.)

       

      3) Check the cable going from the receiver into the camera. The connector with the single BLACK BAND should be connected to the receiver. The connector with the two BLACK BANDS should be connected to the camera.

       

      4) Check to see if your camera is set to auto or manual audio record mode. If the camera is set to manual adjust the audio input level control until satisfactory sound levels are achieved.

       

      5) Lastly, make sure the lapel microphone wire is fully extended, as the cable also doubles as the antenna.

    • Can I use microphones other than the one that came with the transmitter?

      Yes. Azden’s WM-PRO body pack transmitters have a 3.5mm mini-jack, mono microphone input. As long as your microphone has the matching output, it will be compatible with the WM-PRO. If your lavalier mic requires a DC voltage, Azden's WM-PRO transmitters do provide that. If your mic requires phantom power and you're trying to connect it with an adapter cable (XLR to 3,5mm jack) it will likely not work.

    • Can I use multiple receivers with a single transmitter?

      Yes you can. Technically, there is no limit to the number of receivers you use with a single transmitter.

    • What are the transmission frequencies used by the PRO Series transmitters and receivers?

      All PRO Series units sold in North & South America use the same two frequencies: 169.445MHz and 170.245MHz. Other territories are as follows.

       

      Europe (CE): 173.990MHz & 174.700MHz

      Asia: 187.550MHz & 187.900MHz

      China: 203.000MHz & 203.300MHz

    • Can I use rechargeable batteries with my Azden wireless system?

      We recommend using standard alkaline batteries. We do not recommend using rechargeable batteries with any of our VHF and UHF wireless units, mixers or microphones. In general, rechargeables will not last as long as standard alkaline batteries.

    • Why am I only getting audio on the left channel of my camera?

      If you are using the a WR-PRO receiver with a hardwired output cable, this is normal. The reason is that the output cable is mono and going into a camera with a stereo input, it will only make contact with the left channel. This can be easily fixed in most video editing software.

      If you are using a WR-PRO with a detachable output cable (latest versions), it uses a mono to stereo output cable. If you are only getting audio on the left side with this unit, the most likely reason is that you have the output cable connected backwards. Make sure the stereo end (two black rings) is plugged into the camera input. When connected correctly these receivers will output audio on both left and right channels.

      For the WR32-PRO: This model is a 2 channel receiver designed to accept two audio sources simultaneously. The audio of F1 is output on the left and the audio of F2 is output on the right. This is done In order to keep these audio sources separate. Thus when using F1 alone, you will only get audio on the left side of your camera’s input. Again, this can be changed in post production using video editing software.

    • My PRO Series transmitter is showing a red light. Does that mean it's not working?

      No. The light on a PRO Series transmitters is simply a power indicator. It will ALWAYS show a red light when turned on, unless the battery is dead or missing. This light WILL NOT change color when the transmitter is picked up by the receiver.

       

      The light on a PRO Series receiver, however, will change from red to green when a signal is detected on the selected frequency. If this light does not illuminate at all, it means the battery is either dead or missing.

    • How can I get rid of the hiss in my recordings when using a DSLR camera?

      When most people hear noise in their video recordings, they assume it must be the fault of the connected audio equipment. While this is entirely possible, it is not often the case. The most likely culprit is actually your camera’s low quality microphone pre-amp.
       
      Why is your camera’s pre-amp not so good? Camera manufacturers tend to put their development dollars into the functions related to photography. Sound is usually an afterthought and unfortunately the mic inputs on most DSLR cameras are designed to be good enough to work, but are far from being a professional audio input.
       
      Why is the pre-amp adding noise? A microphone pre-amp adds gain (volume) to a connected microphone. And all pre-amps have an inherent noisiness, called a noise-floor. Low quality pre-amps tend to have a higher noise floor and when gain is utilized to increase the volume of the microphone, it also increases the level of the noise floor. This usually manifests as a hiss or white noise being audible in the soundtrack of your video.
       
      What’s the solution? The best options for getting better sound quality are to use an audio adapter/mixer (like the FMX-DSLR) or to use an separate portable recording device.
       
      In both cases, these devices use better, higher quality microphone pre-amps and should reduce any inherent noise present in your video recordings.

    • Wireless: 105/310/330 Series
    • I can’t get both transmitters to work with my 330 wireless system. What’s wrong?

      There is likely nothing wrong with your system. When using two transmitters with the 330UPR please follow these important set-up instructions:

       

      Frequency Selection:

       

      • Turn on one transmitter (35BT or 35HT or 35XT)
      • Change the number in the display window until it reads 30 – 01
      • Turn on the second transmitter (35BT or 35HT or 35XT)
      • Change the number in the display window until it reads 30 – 11

       

      The first number 30 is considered the GROUP number.
      The second numbers 01 and 11 are considered the FREQUENCY numbers.

       

      The transmitters’ should always be on the same GROUP number however the FREQUENCY numbers must always be separated by at least 10 spaces. Separating the channels by less than 10 spaces may result in interference.

       

      Now follow the same set-up on the 330UPR receiver.

      • Turn ON CH1 and CH2.
      • Change the number in the display window until it reads 30 – 01
      • Next hit the button on the receiver marked DISP 1/2 (This button allows you to toggle between channel 1 and channel 2)
      • Change the number in display window until it reads 30 – 11

       

      Now if it is set-up properly you should be able to hit the DISP 1/2 button repeatedly and the numbers should change back and forth in the display from 30 – 01 to 30 – 11. If so, the frequencies are now set.

       

      If you notice any interference using the above combinations please try different GROUP and FREQUENCY combinations.  Such as: 31 – 01 and 31 – 11 or 32 – 01 and 32 – 11.  The main point is to use the same GROUP number and always separate the FREQUENCIES by 10 or more spaces.

       

      Proximity Effects:

       

      When using two transmitters make sure they are both at least 8 feet away from the 330UPR. This will prevent frequency overlapping which will result in noise and short working distance. However, both transmitters will operate properly if they are in close proximity to each other.

    • Is there some way I can use 2 microphones at the same time with my 105UPR or 310UDR receiver?

      The short answer is NO. We’ve had this question asked a lot and we’ve really tried thinking of creative ways to do this using mixers, y-cables, you name it. However, if you need to record with 2 microphones at the same time, your best option is the 330UPR 2-channel receiver. It is compatible with the 35BT, 35HT and 35XT transmitters. Azden does not have a 2-channel receiver that works with 105 Series components.

    • What’s the difference between VHF and UHF wireless?

      Wireless microphones use two segments of the FM radio band, known as very high frequency (VHF) and ultra-high frequency (UHF). VHF is divided into a low band starting at 49 MHz and a high band starting at 169 MHz. UHF frequencies begin at 470 MHz.

      Yes you can. Azden’s wireless microphone systems are designed for use with cameras, but the output of the wireless receiver is microphone level and can be plugged into any input intended for a microphone. However, in the case of hooking up to a PA system, you’ll likely have to convert the output connection from the mini-plug jack to either an XLR or ¼” TS or TRS connection.

       

      The 310 and 330 wireless systems come with either an MX-1 or MX-2 cable, which maybe used to plug the receiver into a microphone level XLR input on a mixer or powered speaker. The 105 systems do not have one of these cables; you will need to purchase the MX-1 cable separately.

    • Can I use my 105/310/330 series wireless system to record into a smartphone or tablet?

      Yes. You can make your current 105 or 310 Series system compatible with a mobile device by using the HX-Mi TRRS Mic/Headphone Cable. Technically, a 330 Series system will work too, BUT you will not be able to use both channels.

    • My 105/310/330 series wireless system is not working properly. Can you repair it?

      Yes we can. See the Service And Warranty page for details. We recommend you give a call first to see if we can troubleshoot your problem over the phone.

    • Can I plug a 15XT or 35XT into the output of my sound mixing board to make it wireless?

      Technically yes, but it is important to note this is not what the 15XT and 35XT were designed to do. However, some customers use XT transmitters for this purpose and it works fine for their applications. To get the best results adjust the XT's gain level to be as little as possible without being “off” (turn the squelch counter-clockwise until you feel resistance, then turn clockwise just a very small amount).

      There are some things to be aware of with this application. The outputs of most mixing boards are line level, which is a hotter signal than the microphone level that the 15XT and 35XT were designed to handle. Distortion will occur unless you are very careful about the output level of your mixer and the gain level of the XT.

      Also the frequency response on 105 and 310/330 Series systems, while great for speech, may not be wide enough for great results in live music or DJ applications.

    • Do you sell parts like battery doors, belt-clips, shoe mounts and lapel clips?

      Yes. You can find these items and more for sale on our website www.azdenproshop.com.

    • Can I use microphones other than the one that came with the body-pack transmitter?

      Yes. Azden’s body-pack transmitters (BT) have a 3.5mm mini-jack, mono microphone input. As long as your microphone has the matching output, it will be compatible. If your lavalier mic requires a DC voltage, Azden's body pack transmitters do provide that. If your mic requires phantom power and you're trying to connect it with an adapter cable (XLR to 3.5mm jack) it will likely not work.

    • Can I use rechargeable batteries with my Azden wireless system?

      We recommend using standard alkaline batteries. We do not recommend using rechargeable batteries with any of our VHF and UHF wireless units, mixers or microphones. In general, rechargeables will not last as long as standard alkaline batteries.

    • Why am I only getting audio on the left channel of my camera?

      For 105UPR and 310UDR receivers: when using the 3.5mm mini jack output cable supplied with the system, these receivers will output audio on both left and right channels. If you are only getting audio on the left channel, the mostly likely reason is that you have the cable connected backwards. Make sure the stereo end (two black rings) is plugged into the camera. If you are connected correctly and still only getting audio on one channel, then the next likely cause is a bad output cable.

      For 330UPR receivers: This model is a 2 channel receiver designed to accept two audio sources simultaneously. The audio of channel 1 is output on the left and the audio of channel 2 is output on the right. This is done In order to keep these audio sources separate. Thus when using channel 1 alone, you will only get audio on the left side of your camera’s input. This can be changed in post production using video editing software.

      If you are using both channels and still only one is getting to the camera, make sure you follow this setup guide. If you are still only getting one channel after following the guide, you could have a bad output cable or possibly your system is malfunctioning. Contact us for further assistance.

    • Can I use a 105 series transmitter with a 310 or 330 series receiver or vice-versa?

      Actually, yes you can. Both 105 and 310/330 systems use the same frequency range. However, 105 systems only have about half the amount of transmission frequencies as 310/330 systems. You’ll have to reference the frequency charts on the Product Manuals page for both systems to figure out how to set up each component so they are on the same frequency.

    • Why is there no audio getting to my camera?

      Most of the time when users call about there being no sound on their video it's because the audio cable connecting the receiver to the camera is reversed. When using the 3.5mm stereo to mono cable (for DSLR cameras) make sure that the stereo connector (two black rings) is plugged into the camera and the mono connector (one black ring) is plugged into the receiver.

       

      Other things to check:

       

      • Make sure the receiver and the transmitter are set to the same Group and Frequency.
      • Make sure you're using fresh batteries (don't use rechargeables).
      • Make sure the microphone level adjustment on the transmitter is not turned all the way down.

       

      Other tips:

       

      • If you can hear audio over the earphone output of your receiver, then you can conclude that the microphone and the wireless units are working properly. You can narrow your troubleshooting to focus on the output of the receiver or the input of the camera.
      • If you're using a 330UPR receiver with two transmitters, follow this setup up guide.
      • If you're still having problems, you can always contact us.
    • Wireless: 1201 & 2000 Series
    • What are the differences between the 1201 Series and the 2000 Series?

      Both Series are capable of high performance and broadcast quality however, the 2000 Series has been designed and uses components that are not affected by extreme heat, cold or humidity. The 2000 Series also offers superior image rejection allowing the signal to come through even in areas with saturated radio signals.

    • Can I use rechargeable batteries with my Azden wireless system?

      We recommend using standard alkaline batteries. We do not recommend using rechargeable batteries with any of our VHF and UHF wireless units, mixers or microphones. In general, rechargeables will not last as long as standard alkaline batteries.

    • Can I use a 1201 transmitter with a 2000 Series receiver and vice-versa?

      No, you can not. While both systems use the same transmission frequencies, 1201 and 2000 systems each use a different method for companding the signal. You might be able to get audio between the two types of units but the quality of it will be noticeably degraded.

    • How many different microphones does Azden offer to work with the 1201/2000BT?

      Both the 1201BT and the 2000BT use a Hirose connection for their microphone input. Azden offers 4 models of lavalier microphones (EX503H, EX505UH, EX-50H, ECM-44H) and 4 models of headset/neck-worn microphones (HS-9H, HS-11H, HS-12H, CM-20DH) with a Hirose connector.

      Additionally, the 1201XT and 2000XT plug-in transmitters will allow you to use any microphone with a 3-pin XLR output with your system.

    • Is there any difference in performance between Slot-In and Portable systems?

      No. Other than mounting configuration, the receivers all offer the same level of performance.

    • Are the transmitters and receivers waterproof?

      No. Though rugged in design, the units are not waterproof.

    • Microphones
    • What is phantom power and does my microphone need it to work?

      Phantom power is a DC voltage supplied through a balanced microphone cable and is used to power the electronics of the connected microphone. Most professional cameras, mixers and audio interfaces with microphone XLR pre amps have the ability to supply phantom power.

      Most commonly, phantom power is supplied at 48V. This is the optimum voltage for Azden's microphones. It is possible that your connecting equipment supplies a different voltage and each Azden microphone has a recommended voltage range that can be used. Be advised that microphone performance will degrade with lower voltages and damage to the electronics could result when using voltages in excess of this range. It is recommended that you consult the manuals of any equipment you intend to use with the microphone beforehand. Please note that the warranty does not cover damage caused by using phantom power beyond what the microphone is rated for.

      In general, if your Azden microphone does not have a battery compartment it will require phantom power to work. Some microphones have the ability to use a battery for power or phantom power, while others may only work on battery. Check your manual or the product page for your model on azden.com to be sure.

      Phantom power is not used at all with lapel, headset and DSLR camera microphones. These microphones do need a power source, but it is a much lower voltage. This type of power is typically called plug-in power (PiP) and is usually provided on mini-jack inputs on cameras and wireless transmitters. Attempting to use phantom power on a microphone that need plug-in power will very likely result in damaging the microphone element.

    • What does cardioid, super cardioid, omni-directional and uni-directional mean?

      All of these terms are used to describe a microphone’s polar or pick-up pattern. The simplest being omni-directional, which means the microphone will pick up sound equally from all directions.

      Cardioid and uni-directional are two interchangeable terms that are used to describe a microphone that is most sensitive to sound coming in directly in-front of the microphone element (on-axis) but will reject some sound coming from the sides and nearly reject all sound coming in from behind. These microphones are better at isolating a sound source in a noisy environment and are best used on a speaking subject up close.

      Super-cardioid is a hyper-directional pick-up pattern, which is very sensitive to all sound in the front of the mic element, and does a very good job at rejecting sound coming in from the sides. Sound sensitivity from the rear is somewhat reduced but not totally. This kind of directionality is found in many of Azden’s shotgun microphones and is best suited for focusing in on sound sources from a distance but can also be used up close.

    • How can I use my Azden microphone with my smartphone or tablet?

      Any of Azden’s microphones with a 3.5mm mini-jack output can be made to work with a smartphone or tablet using the HX-Mi TRRS Mic/Headphone Cable. Compatible Azden microphones include EX-503, EX-503L, EX-505U, EX-50L, ECM-44, HS-9, HS-11, HS12, CM-20D, SGM-990 and SGM-DSLR. Azden’s stereo microphones can work with the HX-Mi but only in mono, since mobile devices do not have stereo microphone inputs. These microphones include SMX-20, SMX-10 and SMX-5. Also available is the SGM-990+i which comes complete with an adapter cable to make it compatible with mobile devices.

    • My microphone is not working properly. Can you repair it?

      Yes we can. See the Service And Warranty page for details. We recommend you give a call first to see if we can troubleshoot your problem over the phone.

    • I have a DSLR, mirrorless or other compact camera. Which Azden microphone is best for me?

      First make sure your camera does have a dedicated 3.5mm microphone input.

      Azden makes a line of camera mount microphones specifically for these types of cameras. The current models are SGM-990, SMX-30, SMX-15, SMX-10 and SMX-5.

    • Where can I buy a replacement shock mount, windscreen or lapel clip for my microphone?

      Yes. You can find these items and more for sale on our website www.azdenproshop.com.

    • Can I use your headset microphones to make phone calls?

      No. While the microphone itself may work for your application, Azden’s headsets do not have a speaker or earpiece for phone use.

    • What does a low-cut filter do on your microphones?

      A low-cut filter is designed to reduce the volume of low frequencies as recorded by the microphone. This can be handy to reduce low frequency background noise such as wind, HVAC systems or traffic. It can also be used to reduce increased bass response due to proximity effect.

      The design of the filter is different depending on which microphone. On the SMX-10 for example, engaging the low-cut reduces low frequencies at 6dB/octave below 200Hz. On the SGM-250, the low-cut rolls off at 160Hz at 3dB/octave.

    • Can I use my Azden microphone in wet conditions?

      Azden’s microphones are not waterproof but should be able to stand up to a little moisture and light rain if exposed infrequently. If you must use your microphone in the rain, it’s best that you try to keep it covered.

    • Which Azden microphones are best for broadcast and film?

      Azden’s SGM line of shotgun microphones are designed for this application. The SGM-3416 and 3416L are Azden’s high performance shotguns, designed to deliver the high quality that any broadcast professional or filmmaker would demand. The SGM-250 and SGM-1X are both great choices for boom work or studio use and were designed with the budget-conscious filmmaker in mind. The SGM-PII and SGM-PDII are great choices for on-camera mounting, with their shorter barrels designed to stay out of view of the camera lens.

    • Can I use rechargeable batteries with my Azden microphone?

      We recommend using standard alkaline batteries. We do not recommend using rechargeable batteries with any of our VHF and UHF wireless units, mixers or microphones. In general, rechargeables will not last as long as standard alkaline batteries.

    • How can I get rid of the hiss in my recordings when using a DSLR camera?

      When most people hear noise in their video recordings, they assume it must be the fault of the connected audio equipment. While this is entirely possible, it is not often the case. The most likely culprit is actually your camera’s low quality microphone pre-amp.

      Why is your camera’s pre-amp not so good? Camera manufacturers tend to put their development dollars into the functions related to photography. Sound is usually an afterthought and unfortunately the mic inputs on most DSLR cameras are designed to be good enough to work, but are far from being a professional audio input.

      Why is the pre-amp adding noise? A microphone pre-amp adds gain (volume) to a connected microphone. And all pre-amps have an inherent noisiness, called a noise-floor. Low quality pre-amps tend to have a higher noise floor and when gain is utilized to increase the volume of the microphone, it also increases the level of the noise floor. This usually manifests as a hiss or white noise being audible in the soundtrack of your video.

      What’s the solution? Whether using one of Azden's DSLR microphones or professional XLR shotguns microphones with a 3.5mm adapter, the best options for better sound quality are to use an audio adapter/mixer (like the FMX-DSLR) or to use an separate portable recording device.

      In both cases, these devices use better, higher quality microphone pre-amps and should reduce any inherent noise present in your video recordings.

    • Mixers
    • Do Azden mixers provide phantom power?

      Yes, all of Azden’s FMX mixers have phantom power, switchable on & off for each channel.

    • What kind of outputs do Azden mixers provide, line level or microphone level?

      All of Azden’s mixers can output microphone level. With the FMX-42u and 42a you have the additional ability to output line level if needed.

    • How do I know which Azden mixer is right for me?

      First consider the kind of outputs you need for your camera. Azden’s FMX-42a, 42u, 32a and 22 have both XLR outputs and 3.5mm mini-jack stereo outputs at microphone level. Additionally, the FMX-42u and FMX-42a can also output line level. The FMX-DSLR outputs only a 3.5mm stereo mini-jack for DSLR cameras. It is also compact and designed to mount underneath a DSLR camera. Lastly, the FMX-42u is the only Azden mixer with a digital USB output which you can use to record audio to a mobile device or a computer.

      Next, consider how many microphones you may need to record with at one time. The FMX-42u and FMX-42a offer 4 input channels, while the FMX-32a offers 3 and the FMX-22 and FMX-DSLR offer 2. And what kinds of microphones are you using? The FMX-42a, 42, 32a and 22 all take XLR inputs while the FMX-DSLR also accepts a 3.5mm mini jack microphone input.

      Another feature set to consider may be whether you need camera returns on your mixer to monitor audio directly from your camera. The FMX-42a and FMX-DSLR offer this feature.

      If all of this sounds like overkill to you, the CAM-3 mixer may be what you’re looking for. It takes only 3.5mm mini-jack inputs and could allow you to mix together 3 different microphone sources (2 mono, 1 stereo), like a WLX-PRO with an EX-413 and an SMX-10, for example. The CAM-3 outputs to a 3.5mm stereo mini-jack.

    • What’s the difference between the FMX-42u and FMX-42a?

      The FMX-42a provides a 10-pin camera return and a mini-jack camera return for monitoring audio from the camera. The FMX-42u lacks any return monitoring capability but has a stereo digital audio USB output for recording to mobile devices and computers. Aside from these unique features, the FMX-42a and FMX-42u are identical.

    • My Azden mixer is not working properly. Can you repair it?

      Yes we can. See the Service And Warranty page for details. We recommend you give a call first to see if we can troubleshoot your problem over the phone.

    • I lost my mixer’s power supply A/C adapter. Where can I buy a new one?

      The FMX-42a and 42 mixers use the BC-27H power supply and the FMX-32a and FMX-22 use the BC-27. You can find these items and more for sale on our website www.azdenproshop.com.

    • Can I make my Azden mixer work with a smartphone or tablet?

      We created the FMX-42u specifically for this purpose. It has a digital audio output via USB which can be connected to smartphones, tablets and computers. The required "USB mini-B male to USB A male" cable is not included and will need to be purchased separately. Special note: For recording to an iOS device, you'll need to purchase an Apple® Lightning™ to USB Camera Adapter cable in addition to a USB cable.

       

      For other mixers, technically you can use an HX-Mi TRRS Mic/Headphone Cable to record to a mobile device with an Azden mixer. However, it is important to note that you will not be able to mix in stereo using this cable into a smartphone or tablet. For best results, on the FMX-42a/42u pan your mixer’s channels hard left. For the FMX-32a/22 make sure your channel’s pan switch is set to L (left). On the FMX-DSLR, you will be limited to using the MIC 1 input.

       

    • Can I use rechargeable batteries with my Azden mixer?

      We recommend using standard alkaline batteries. We do not recommend using rechargeable batteries with any of our VHF and UHF wireless units, mixers or microphones. In general, rechargeables will not last as long as standard alkaline batteries.

    • i-Coustics™
    • Can I make my Azden microphone work with my smartphone/tablet?

      Any of Azden’s microphones with a 3.5mm mini-jack output can be made to work with a smartphone or tablet using the HX-Mi TRRS Mic/Headphone Cable. Compatible Azden microphones include EX-503, EX-503L, EX-505U, EX-50L, ECM-44, HS-9, HS-11, HS12, CM-20D, SGM-990, SMX-15 and SMX-30 (mono mode). Azden’s stereo microphones can work with the HX-Mi but only in mono, since mobile devices do not have stereo microphone inputs. These microphones include SMX-30 (stereo mode), SMX-10 and SMX-5. Also available is the SGM-990+i which comes complete with an adapter cable to make it compatible with mobile devices.

    • What is Azden i-Coustics®?

      i-Coustics® is a sub-brand of Azden products designed to work with smartphones and tablets. Learn more at www.azden.com/i-coustics.

    • What mobile devices are compatible with i-Coustics® products?

      Popular mobile devices such as the iPhone®, iPad®, Samsung Galaxy S®, Galaxy Tab® and most other Android™ devices are all compatible with i-Coustics® products. You can see a full list of compatible devices here.

    • I don’t see my device on the list of i-Coustics® Compatible Devices. Does that mean i-Coustics®

      Not necessarily. Any mobile device with a TRRS microphone/headphone jack will be compatible with i-Coustics™ products. An easy way to figure out if you’re device is compatible: check to see if the earbuds that came with your device have a microphone on them to allow you to make hands-free calls or video chat. If they do, then Azden’s i-Coustics® products will most likely work with your device. If your mobile device did not come with earbuds, check the owner’s manual and see if it has the capability to accept an external microphone. If it does, it is most likely incorporated into the headphone jack with the standard TRRS connection, which will work with i-Coustics™ products.

    • Can I make my Azden mixer work with my smartphone/tablet?

      Technically you can use an HX-Mi TRRS Mic/Headphone Cable to record to a mobile device with an Azden mixer. However, it is important to note that you will not be able to mix in stereo using this cable into a smartphone or tablet. For best results, on the FMX-42a/42u pan your mixer’s channels hard left. For the FMX-32a/22 make sure your channel’s pan switch is set to L (left). On the FMX-DSLR, you will be limited to using the MIC 1 input.

    • Can I make my Azden wireless system work with my smartphone/tablet?

      Yes. You can make your current single channel PRO, 105 or 310 Series system compatible with a mobile device by using the HX-Mi TRRS Mic/Headphone Cable. Technically, a dual-channel PRO Series or a 330 Series system will work too, BUT in order to use both channels you’ll need an additional adapter to sum the stereo output to mono. In this case, however, you will not have the 2 channels of the receiver separated on the left and right channels of your audio/video recording.

    • Will my Azden dual-channel wireless system record both channels using the HX-Mi cable?

      No. At least not with out using an additional adapter. If you connect the stereo output cable from your dual-channel receiver to the HX-Mi cable, you will be able to record audio using channel 1 only. This is because mobile devices, and thus the HX-Mi cable, only accept a mono microphone input. However, you can get around this by using a 3.5mm stereo female to 3.5mm mono male adapter between the stereo output cable and the HX-Mi. This will sum the 2 channels of the receiver to 1 mono signal.

    • Will my Azden stereo microphone record in stereo using the HX-Mi cable?

      No. Mobile devices, and thus the HX-Mi cable, only accept a mono microphone input. You can still record into your mobile device using a stereo microphone (SMX-20/10/5) and the HX-Mi cable but the recording will be mono.

    • What recording apps can I use with Azden i-Coustics® products?

      For video, the standard video recording app included with iOS and Android devices works seamlessly with i-Coustics® products. Most third party video recording apps should work just fine as well.

       
      For audio alone, just about any recording app should work when using i-Coustics® products. Here are some that we have tried and like. For iOS devices: Apple’s Voice Memos App, SoundCloud App and GarageBand. For Android devices: Smart Voice Recorder, HD Audio Recorder and the Soundcloud App.

    • Digital Wireless
    • What is 2.4 GHz digital wireless technology?

      Most digital wireless technology operates in a narrow UHF band around 2.4 GHz. This is the same technology used by Wi-Fi routers and Bluetooth audio devices. Digital wireless has the advantage of being free from interference with radio and TV frequencies and in general exhibits better audio quality. However, digital wireless is not without its cons and has its own set of challenges. Limitations such as crowded Wi-Fi environments and dependence on line of sight for long range operation are the main downsides with digital wireless microphones. In order to cope with the crowded Wi-Fi environments, Azden adopted an encrypted digital transmission signal that constantly monitors and hops between frequencies to select the strongest signal.

    • Can I use the PRO-XD wireless system with my smartphone or tablet?

      Yes you can. The PRO-XD is part of the Azden i-Coustics sub-brand, which means it is compatible with many different mobile devices. The PRO-XD can be connected to a mobile device using the included TRRS audio adapter cable, which plugs into the connecting device’s headset input.

    • What should I do if I’m having problems with my PRO-XD system?

      Please follow these 8 Tips For Best Results. If you believe your system is defective, consult our Service And Warranty page.

      1. For each use of the PRO-XD, be sure to start with both units fully charged.
      2. Position the transmitter and receiver with as few physical obstacles between them as possible. A clear line-of-sight is always best.
      3. The human body is an efficient absorber of 2.4GHz signals. Keep this in mind when choosing where to clip the transmitter or where to mount the receiver. Clipping the transmitter behind a person’s back or in a back pocket, for instance, may reduce the range of the system.
      4. When using the PRO-XD with a camera, set the volume level of the receiver to its maximum and then reduce the gain at the camera to get a strong audio signal without overloading. If additional reduction in gain is still needed, back off the volume on the receiver until levels are optimized. In general, it is best to engage the preamp on the camera as little as possible.
      5. The PRO-XD system will work reliably at a distance up to 100 feet (or possibly more) in optimal conditions. However, its performance at long distances depends heavily on the Wi-Fi environment and clear line-of-sight.
      6. Always test the PRO-XD system in a new location by monitoring its performance for a few minutes before beginning your shoot.
      7. Crowded Wi-Fi environments can make it challenging for the PRO-XD to find a clear channel on which to connect. A crowded Wi-Fi environment will also limit the number of PRO-XD systems that can be used simultaneously in the same area. Consider these limitations when choosing your location.
      8. When experiencing connectivity problems, turn off all unnecessary 2.4GHz wireless devices in the area if possible. This includes devices like routers, hot-spots, Bluetooth devices, computers, cell phones (use airplane mode), etc.
    • How can I get rid of the hiss in my recordings?

      When most people hear noise in their video recordings, they assume it must be the fault of the connected audio equipment. While this is entirely possible, it is not often the case. The most likely culprit is actually your camera’s low quality microphone pre-amp.
       
      Why is your camera’s pre-amp not so good? Camera manufacturers tend to put their development dollars into the functions related to photography. Sound is usually an afterthought and unfortunately the mic inputs on most DSLR cameras are designed to be good enough to work, but are far from being a professional audio input.
       
      Why is the pre-amp adding noise? A microphone pre-amp adds gain (volume) to a connected microphone. And all pre-amps have an inherent noisiness, called a noise-floor. Low quality pre-amps tend to have a higher noise floor and when gain is utilized to increase the volume of the microphone, it also increases the level of the noise floor. This usually manifests as a hiss or white noise being audible in the soundtrack of your video.
       
      What’s the solution? For wireless microphones that use a mini-jack connection, the best solution is to set up good gain structure between the receiver and the camera. If you are able to set the microphone recording level on your camera, it is generally best to keep the camera’s gain level low and set the output level of the receiver very high. This is because the preamps in most cameras tend to be of low quality and will add noise to the recording if a lot of gain is used. The output of the PRO-XD was designed to provide a strong audio signal to a camera so that gain levels on the camera’s microphone input should not have to be turned up very high.
       
      Follow these steps for optimal recording levels:

      1. Turn on the transmitter and plug in the microphone.
      2. Turn on the receiver and make sure it is paired with the transmitter. Press the plus (+) button on the Volume Control 6 times to set the output volume to maximum.
      3. On your camera, go to the microphone gain settings. As you speak into the microphone to test levels, observe the audio meters and set the camera’s gain level so that your audio peaks are slightly below the max output level (avoiding distortion). If you can monitor your camera’s audio with headphones, listen to make sure no distortion is audible.
      4. If you’ve reduced the camera’s microphone gain as much as possible and you’re still getting distortion, press the minus (-) button on the receiver's volume control until the audio is no longer distorting.
    • How many PRO-XD systems can I use in the same area at the same time?

      As many as 4 or more PRO-XD systems should be able to operate simultaneously in the same area, assuming optimal conditions. This number may be less if the 2.4 GHz environment is crowded by other devices.

    • Can I use multiple receivers with one transmitter?

      Yes. This is typical in most wireless systems and the PRO-XD is not an exception here. You can theoretically use an infinite amount of receivers with the same transmitter.

    • Can I use multiple transmitters with one receiver?

      No. Unfortunately the way the PRO-XD works limits it to one channel or one transmitter at a time.

    • Why is there an echo when I listen to myself talking with headphones?

      The echo you hear is due to latency. All digital audio systems exhibit some amount of latency, which is a delay between the audio source and the system’s audio output. Humans are very sensitive to time delays in sound but much less so with timing delays between audio and visual events. As a result, while you may be able to hear the latency of the PRO-XD system, it is still small enough to be unnoticeable in video recordings.

    • Is there a solution for connecting the PRO-XD to an XLR connection?

      Yes there is. You'll want to use Azden's adapter cable, the MX-2.

       

      You may be wondering: Why does the MX-2 have 2 XLR connectors? Don't I just need one? Because the output of the PRO-XD is stereo, you'll need to use the MX-2 as it has a stereo mini-jack connection. If you're only using the mono microphone, you can plug just one (doesn't matter which) XLR connector into your camera or mixer. If you're using the stereo AUX input, then you'll likely want to plug in both XLR connectors.

    • Can I use a different microphone than the one came in the PRO-XD kit?

      Yes you can but the microphone needs to have the correct connector type. The PRO-XD transmitter accepts a 3.5mm TRRS male connector, the same type of connector that many smartphones use.

      Technically, any microphone that has a 3.5mm TRRS connector will work with the PRO-XD transmitter. Azden's EX-503i is compatible but we don't recommend using it; because of it's high sensitivity, the output of the EX-503i is a little bit too hot for the PRO-XD, and you might get some distortion.

      If the microphone you wish to use has a 3.5mm TS (mono) connector, it can be made compatible with the PRO-XD by using the included TRRS adapter cable. Additionally you could purchase Azden's HX-Mi TRRS Adapter cable separately if you would also like to use the system with a smartphone or tablet.
