Output Switching 

 
A1/A2 

These buttons select either: 

 

-

 

The  Analogue  Left  or  Right  signals  of  the  metered 

Input,  

 

- The AES/EBU Input 1 Left or Right signals or  

 

- The selected SDV group A1 & A2 decoded outputs to 
the Left or Right Output Channels.   

 

The buttons toggle.  Additive  mixing  is  possible  if  two 
or more buttons are selected together. 

 
A3/A4

 

These buttons select either: 

 

- The AES/EBU Left or Right signals of Input 2 or,  

 

- The selected SDV group A3 & A4 decoded outputs to 
the Left or Right Output Channels.   

 

The buttons toggle. Additive mixing is possible if two or 
more  buttons  are  selected  together  when  Digital  I/P  1 
(SDV/AES) is selected on the input. 

 
DIM 

Approximately 16dB of attenuation is switched into the 
audio  path

 

and  is  effective  on  the  loudspeaker  and 

variable  line  outputs.  The  fixed  line  outputs  are 
unaffected. 

 
 
CUT 

The front panel button cuts the signal to the 
loudspeaker and variable line outputs. The fixed line 
outputs are unaffected. 

 
VOLUME

 

The Headphones O/P and the Variable Line O/P may 
be varied.
