 |
|
I posted this on the AeroElectric List but the silence was deafening (except for
the continuous off-topic political arguing).
Can someone with actual hands-on experience with the Garmin GMA 240 Audio Panel
answer this question, please? Is the volume of the "Failsafe Warning Audio"
(P2402 pin 29) controllable or is it fixed?
The installation manual implies it's useful for an audio input that will be
audible in the pilot headset even if power is removed. It seems like an obvious
choice for my Dynon Skyview EFIS warning audio but not if the audio level is
not acceptable and cannot be set. In that case, one of the ALERT, AUX, or even
NAV audio inputs would work better -- except in the case of power failure.
Or maybe it's wired in parallel with one of the other inputs to provide an
adjustable level under normal conditions and some arbitrary level after a power
failure.
Has anyone used this feature?
Thanks,
Joe
