    Product Info Sheet



    • 1.Digital Wireless
    • What is 2.4 GHz digital wireless technology?
      admin08-07-2015

      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?
      admin08-07-2015

      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?
      admin08-07-2015

      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?
      admin08-07-2015

      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?
      admin08-07-2015

      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?
      admin08-07-2015

      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?
      admin08-07-2015

      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?
      admin08-07-2015

      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?
      admin05-08-2015

      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?
      admin06-08-2015

      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.
