LOW MICROPHONE OUTPUT LEVEL

The microphone output level is sensitive when it comes to the position of the microphone and distance from your mouth.

On the Avee we are using a noise cancelling microphone to get as little cockpit noise as possible in both the intercom and on the radio. The nature of this is that it picks up sound from the near proximity ONLY.
It will not pick up sound from distances more than 10mm.

MICROPHONE CHECKLIST

Here we have two very important things to remember:

1. The white spot on the microphone and the flat side of the microphone MUST face your mouth.
   When wearing the microphone you will not be able to see the white spot, but you can feel that the flat surface is facing your mouth.
2. Make sure that the microphone is not twisted so the flat side is not facing your mouth.
3. The distance between your mouth and the microphone is critical.
   The optimal distance between the microphone and your lips – is that your lips should touch the microphone foam / wind protection.
   For all practical purposes we say maximum 5-10mm between the microphone and your lips.
4. The output level from the microphone should normally be set to 4 (the factory setting).
   Adjusting the volume level from the microphone itself will not help much if the microphone is not picking up your voice, so please make sure to follow steps 1 to 3 above.

LOSS OF AUDIO

Permanent or sporadic loss of audio in both headset left and right side of the headset means that there is either a bad connection or no connection at all between the Avee microphone and the headset.

The golden rule here is that if you can not hear yourself talking – something is wrong.

Check the following points:

1. Magnet connection on Avee:
   Make sure only one magnet is installed – and that it is correcly  installed leaving no gap between the Avee microphone and the headset.

   The Avee solution  is based on a perfect connection between the headset and the Avee microphone.
   If this is not the case, it can lead to speaker audio drop outs and potential loss of ATC and intercom communication in left ear, right ear or even both ears.It is therefore extremely important to follow the descriptions given when installing the Avee microphone  and the adhesive magnet to the headset.
   We have made a video showing how the installation is done on the Avee microphone and you can find that here: Avee Setup Instructions.

2. Intercom squelch  setting:
   Ensure that the intercom squelch in the aircraft is fully open.
   Verify you can hear your own voice when talking.
   Adjust the intercom to normal level so no hissing is heard.

LOSS OF AUDIO IN RIGHT EAR

Occasional loss of sound in right ear is most likely caused by the fact that the Avee microphone is detecting audio (or noise) from the aircraft right channel, and then switches to stereo mode.

In case your aircraft is not equipped with a stereo audio system, you can loose the audio in the right ear when this happens.
To verify that this really is the problem, unplug the Avee from the aircraft for a few seconds (unplugging the thin 5.2mm connector is enough), and plug back again.
If you now get audio in both ears, the mono / stereo setting is the problem.

This behavior is easily fixed by forcing the Avee microphone to always be in mono mode.
Follow the description found in the Avee microphone User Guide and the chapter ‘Changing mono & stereo mode’.
The User Guide can be downloaded from the Download area.
