Description
•
input /IC (Pin P1-7) activates intercom only from
microphone path 1.
“OUTPUTS”
HDPH 1
ENABLED - audio available on headphone 1 output
(Pins P1-2/P1-3).
HDPH 1
DISABLED - no audio is available on headphone 1
output.
HDPH 2
ENABLED - audio is available on headphone 2 output
(Pins P1-20/P1-22), speaker not available.
HDPH 2
DISABLED – no audio available on headphone 2
output, speaker not available.
SPEAKER
ENABLED - audio is available on speaker (Pins P1-
1/P1-14), headphone 2 not available.
NONE
- no audio on headphone 2 output or speaker output.
Note:
Displayed only if MIKE_SW input (Pin J1
-
24) has
Inactive state.
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 sensitivity of standard microphone 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 ambient
noise suppression as high as possible, this will ensure correct
modulation.
If the sensitivity is adjusted to a smaller value (e.g. 10 mV) the
ambient 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 ambient noise is very much reduced, but the
modulation of the transmitter might not be 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:
For installations with high interferences it is
recommended to use sensitivity level 27 mV to 1500 mV.
