--> Avionics-List message posted by: "James Redmon" <james@berkut13.com>
Hi all,
I've found a small anomaly in my audio system - specifically the KA-135
audio panel...I think. I have two com radios, the KA-135 has the two
mic/radio select buttons and several inputs for aux audio (NAV1, NAV2,
Marker, DME, etc.) - standard stuff, right.
I have the audio from the engine computer (audio alerts) piped into the
KA-135 on one of the 5 aux audio lines. With com1 mic switch pushed, all is
fine...everything loud and clear. Problem: when com2 switch is activated, I
can hear com2 audio just fine but ALL other audio inputs seem to have been
muted considerably. I can still hear them but they ALL are significantly
lower in volume. This also happens to all aux audio when the "both" button
is pressed as well. The result - when I'm monitoring com2, I can barely
hear the audio warnings....not good!
I have checked side tone adjustments on the both coms..no effect. The only
volume adjustment that the KA unit has is for the external speaker...it is
unaffected by the mic select button positions.
You can get a look at my panel here: http://www.berkut13.com/berkut22.htm
Can any of you KA-135 users/fixers out there verify that this is normal?
Is there any way to adjust or change this operation mode? There is noting
the manual that describes this behavior.
Thanks all!
