Low audio from product

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.

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.

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.

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

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.
