    • 1.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. 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 105/310/330 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 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.
