Note:
This page is only displayed if :
- Standard Mike 1 input is
selected in “IN/OUT CFG1”
and “MIKE_SW” input pin
status is inactive
- or “Standard Mike 1” input
is selected in “IN/OUT”
CFG 2 and “MIKE_SW” input
pin status is active
The sensitivity of Standard Microphone 1,
“STD 1 MIKE SENS”, input is adjustable
within a range of 9 mV to 1500 mV by
turning the “ROTARY ENCODER”.
The factory setting is 110 mV.
The VU meter display the current signal
level on the audio input and keep on
showing the highest signal value for 3
seconds.
While you are speaking with a normal voice
level to the microphone, for most of the
time, a convenient sensitivity is achieving
and the bargraph remain within the
predefined area.
Note:
The microphone sensitivity shall be adjusted to
achieve a correct modulation by keeping the cockpit
noise suppression as high as possible.
If the sensitivity is adjusted to a smaller value
(e.g. 10 mV) the cockpit noises may become louder than
for a higher adjustment (e.g. 100 mV).
Otherwise, adjusting the sensitivity to a very high
value (e.g. 1000 mV), the cockpit noise is very much
reduced, but the modulation of the transmitter might
be not sufficient.
The installer shall perform a communication check
after modification of this parameter. Recommended is
to perform this check with and without a running
engine.

This page is only displayed if :
- Dynamic input is selected
in “IN/OUT” CFG1 and
“MIKE_SW” input pin status
is inactive (open).
- or Dynamic Mike input is
selected in “IN/OUT” CFG 2
and “MIKE_SW” input pin
status is active (closed)
The sensitivity of the Dynamic Mike, “DYN
MIKE SENS”, input is adjustable within a
range of 0,5 mV to 25 mV by turning the
“ROTARY ENCODER”.
The factory setting is 3.5 mV.
