The sensitivity of standard m
icrophone 1, “STD 1
MIKE SENS”, input is adjustable within the
range 9
mV to 1500 mV by turning the “ROTARY ENCODER”.
The factory setting is 110 mV.
The VU meter displays
the current signal level on
the audio input and also displays
the highest
signal value for the last 3 seconds.
When speaking normally into the microphone the bar
graph should remain within the
recommended
predefined range
Note:
Adjust the microphone sensitivity by keeping
the cockpit n
oise suppression as high as possible,
this will ensure correct modulation.
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 sensitivit
y 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.
Note 2: Menu available on primary
controller.
Note:
For installations with high interferences it
is recommended to use sensitivity level 27
mV to
1500 mV.
STD 2 MIKE SENS

The sensitivity of Standard Microphone 2 Input can
be adjusted in range from 9 mV to 1500 mV by
turning the rotary knob.
The default setting is 110 mV.
VU meter displays current value of Audio Level
from standard microphone input
2
and displays the
highest value of Active Audio Level recorded
during last 3 seconds.
Correct sensitivity is achieved when you are
speaking normally into the microphone, this is
confirmed by the “Hold max level bar” remaining in
“Recommended range”.
