Description
"STD2 MIKE SENS":
The sensitivity of standard microphone 2 input can be adjusted in range
from 9...1500 mV by turning the "ROTARY ENCODER".
20 dB 150 mV
VU
STD2 MIKE SENS
Note: This page is only
displayed if :
Standard Mike 2 input is
selected in IN/OUT CFG1
and MIKE_SW input pin
status is [Inactive]
or
Standard Mike 2 input is
selected in IN/OUT CFG2
and MIKE_SW input pin
status is [Active].
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".
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 value is very small (e.g. 10 mV) more cockpit noise will
be heard than if the sensitivity value is set to a higher level
(e.g. 100 mV).
Alternatively if the sensitivity value is very high (e.g. 1000 mV) the
cockpit noise will significantly be reduced but the modulation of the
transmitter may not be sufficient.
After modifying this parameter a communication check shall be done by
the installer. It is recommended to perform this communication check
with and without engine running.
Note: Menu available on primary controller.
For installations with high interference it is recommended to use
sensitivity level 27...1500 mV.
"STD3 MIKE SENS":
The sensitivity of standard microphone 3 Input can be adjusted in range
from 9...1500 mV by turning the "ROTARY ENCODER".
20 dB 150 mV
