The balanced group outputs are adjusted by the Group 1 and Group 2 masters 
[39] on the master module.
Active-Balanced outputs are standard on the group outputs but may be 
ordered with transformer-balanced outputs.
 
Each group channel has ¼" TRS send and return insert jacks. The insert jack 
provides line level inter-stage access to the group bus before (pre) the Group 
Master level control. This means that any device interfaced to these jacks will 
not be affected by any adjustments of the Group Master control.
 
The insert jacks may be utilized to connect processors such as limiters, 
equalizers, or noise reduction. 
The active-balanced electronic circuitry of each group insert return is 
completely bypassed via a relay until a plug is inserted into its respective 
insert return jack.
These balanced ¼" TRS jacks are available for hooking up a power amp or 
powered speakers. The signal present at these jacks is adjusted by the 
Monitor Master control on the front panel.
These active-balanced 1/4" 
TRS connectors allow the 
interface of an external stereo 
signal, such as a DAW, DAT, 
CD recorder/player, or any 
stereo line level source. These 
inputs are selected with the 
Monitor Select [26] on the 
master module. The 2T and 
DAW returns may be operated 
in mono when a single signal 
is plugged into the left input 
jack only.
