Low audio from product

If the volume level heard from your product is faint or quieter than normal, try the following:

Determine if the issue occurs with a connected auxiliary device.

Put the audio selector switch on the headset control module in either the middle or top position. (Be sure it is not in the down / Intercom Only position.) Then, disconnect the headset from the panel and connect an audio device to the 3.5 mm aux input on the headset control module. If you have a headset with Bluetooth®, you can connect a Bluetooth device instead: If the issue still occurs with the aux device, there is an issue with the headset; if the issue is not present with the aux device, the issue is related to the panel settings or connections.

Be sure the headphone openings are clean and free of debris.

Check for blockages in the headphone mesh grille and headphone opening. Excessive debris can result in low audio, poor sound quality or missing audio channels.

Connect the headset to a different panel jack or, if possible, to another aircraft.

Non-TSO equipment, worn jacks/loose connections, or incorrectly wired jacks (i.e. reversed stereo or mic / ground wires) in the aircraft can cause issues. If available, try connecting the headset to another jack in the aircraft or to jacks in a separate aircraft. If the headset works fine when connected elsewhere, the panel jack or wiring to the jack is the issue.

Plug in a different headset.

If available, connect a different headset to the aircraft to determine if the issue is related to the aircraft panel or its settings.

Disconnect all other headsets connected to the aircraft.

Unplug any other headsets connected to the aircraft intercom. If the issue goes away, it is related to another headset. Reconnect the headsets one-by-one to determine which, then check the settings for that headset.

If the issue only occurs with a device connected to the auxiliary input, here are some suggestions.

Try the following:
