JA95-001 Audio Controller 

 

Operating Manual

 

Page 5 

 

 

This is a customizable dead-front 
annunciator activated by an external 
switch.  

When enabled, it will illuminate when 
a ground is applied to the CALL input 
from another user’s audio controller 
or by a remote ‘call’ button within the 
aircraft. 

 

This is a rotary knob used to select the 
VOX threshold of the unit

See

 

below. 

 

When rotated fully clockwise (cw), the 
threshold will be at maximum and VOX 
ICS operation is disabled and ICS PTT 
input is required for ICS operation.  

When rotated fully counterclockwise 
(ccw), the threshold will be at minimum 
(almost live). 

This is a customizable legend to 
mark the PA position for the 
transmit selector.  

The interchangeability allows an 
appropriate name for this legend 
to be selected. 

 

Note

:  Check with your installing agency for confirmation of the 

operation of this annunciator. The legends are interchangeable 
to allow customization.

VOX Threshold Control  

 

 
 
To adjust the unit for 

VOX

 (Voice activated) use, the VOX control should 

be set fully ccw and then slowly rotated cw to the point where no intercom 
audio can be heard. The VOX control should be adjusted for proper 
operation according to the ambient noise.
