MASTER SECTION CONNECTIONS

Pin 1 Lift

This recessed switch is used to disconnect Pin 1 from ground on the MONO

output XLR connector. Used to eliminate ground loops when connecting up different
pieces of equipment Use a pencil or other thin probe to activate the switch; Pin 1 is
lifted when the switch is IN.

Mono

Output

Main Mono output. Normal source is a mix of L&R Pre-insert signals. User

may select; either Post-insert L&R or Post-fader L&R. (See USER CONFIGURED
OPTIONS section). Output level is controlled by MONO OUT control and MUTE
button on front panel.

balanced XLR. Pin 2 hot, Pin 3 low, Pin 1 ground.

unbalanced. These outputs are self-compensating electronically

balanced. They can be operated unbalanced with either polarity, by taking the

signal from the desired pin

and tying the unused output

pin to ground. The output of the driving pin will increase

6dB to compensate for

the loss of the grounded pin.

Aux Out A, B, C, D

jacks,

unbalanced outputs of the Auxiliary buses. Aux A B are normally

set up as Pre-EQ and are typically used to generate a stage monitor mix. Aux C

D are normally Post-fader and are used for EFX sends. The individual mixes are set
up using the Aux sends on each channel and the overall level is determined by the

Aux Master controls. The output of each Aux can be monitored by depressing the

appropriate switch in the Monitor Select section. Nominal level of

Stereo Out

This

stereo jack is normally the Pre-insert output of the Left Right mix

amps. Tip is Left, Ring is Right. The Level and Muting are controlled by the front
panel controls associated with the STEREO OUT section. Additionally, the user can
change this output to follow either the Post-insert or Post-fader signals of the L
mix amps(See USER CONFIGURED OPTIONS section). Output level is variable,
max output is

into 600 Ohm or greater.

Monitor Out

This

stereo

jack

follows the Monitor Select switches and Auto-PFL. The

output level is controlled

by the

Monitor Level control on the front panel. Use this
