Installation Guide & User Instructions 

Configuration

Default settings

The RCom is supplied ready to use.  However, there are several settings 
that can be adjusted if required.
The RCom is designed to be very simple to use in normal operation.  The 
configuration system uses the existing controls, and these notes should be 
read carefully in order to understand the set-up procedure.
The default settings can be restored by powering up the device with both 
buttons held in for several seconds.

Adjustable settings

There are four settings that can be adjusted by the user.

1. Com Pan:

  When stereo headphones are used, the position of the com 

signal in the stereo field can be adjusted.  The reason for this is that when 
monitoring an auxiliary signal on the headphones, the com signal can be 
panned to one side to help the user distinguish between the signals.  This 
does not affect the sound heard by other users.

2.   Mic   Null:

    It   is   possible   to   reduce   the   level   of   the   users   own 

microphone   in   his/her   headphones.     This   is   done   using   a   cancelling 
technique, and near the top end of the control the microphone level can be 
reduced to virtually zero.  This does not affect the microphone level on the 
rest of the circuit as heard by other users.

3. Mic Gain:

   This level can be adjusted to suit various microphone 

types.  The default value is suitable for most dynamic microphones.  This 
setting DOES affect other users on the system, and care must be taken to
