Microphone picks up too much sound | Bose A20 Aviation Headset
Determine if any recent changes have been made to the headset or aircraft.
If any changes or modifications have been made to either the headset or the aircraft, look into whether or not those changes could have unexpectedly caused this issue.
Be sure the microphone is positioned correctly.
- Position the microphone with its labelled / marked side facing your lips
- The microphone should be slightly off center from your mouth
- The microphone should not be further than 1/2" (1.5 cm) from your lips
- Avoid contact with the microphone and your lips
Check the audio panel settings.
On the audio panel, adjust the squelch setting to match the headset mic level. Open or close the squelch setting while speaking into the mic until the mic signal is clear and consistent. Some audio panels have an Auto-Squelch (VOX) feature which can still be manually adjusted using squelch controls.
Check the type of aircraft you're using the headset in.
If you fly a loud aircraft, such as an Otter, Beaver, Pitts, Christian Eagle, or an aircraft with an open cockpit, we recommend using the Oregon Aero MicMuff for enhanced noise protection. For more details, visit their website at www.oregonaero.com or call 800-888-6910.
