Depending on what bridged mode are active the appropriate LED will illuminate above the 
power switch: 
 

There are some changes operationally 
when a pair of channels are bridged. 
 
Channel MUTE keys will be automatically 
ganged; 
 
Meters for the bridge pair will read 
identically; 
 
and lastly 
 
 
 
 
 

 
Channel EDIT keys will be automatically ganged, and the display reflects the bridged mode 
by changing to show the following when a bridged pair are edited: 
 

 

 

 
 
 
 
 
 
In this example, the bridged pair are outputs 1 & 2 and this will be displayed if EDIT is pressed 
on either output channel. 
 
Bridged status is stored in an output memory, and ignored if this memory is recalled into the 
auxiliary channels.
