Rear Connections
The rear connections facilitate the numerous inputs and outputs
necessary for successful mixing. Since the console is of little
use until it is wired into a whole system, an understanding of
what each input and output does is necessary before it can be
properly connected. Use the descriptions and diagrams on the
next two pages to plan your cabling scheme.

Unless specified, nominal levels are:
O VU = +4dBu = 1.23V RMS
Max Level = +28 dBu balanced, +22dBu unbalanced

Line In - greater than 10kΩ
Outputs -140Ω
Input Module Connections
Direct Out
This unbalanced 1/4" TRS jack delivers the direct output signal
(post fader & post mute) from the associated
input channel.
Insert Send
This unbalanced 1/4" TRS jack is used for
sending a post-input preamp, post Hi Pass
Filter, pre-EQ signal to an outboard proces-
sor. The signal at this jack is unbalanced and
always active regardless of the Insert Switch
setting.
Bal Insert Return
This balanced 1/4" TRS jack receives it’s
signal from an outboard processor. It can
also be used to bring a signal into the chan-
nel, bypassing the input preamp and gain
circuit. The return input is balanced and
must be enabled by depressing the channel
Insert switch.
Bal Line In
This balanced 1/4" TRS jack accepts a bal-
anced or unbalanced line level input, and
delivers it to the input selector switch.
Mic In
This female XLR connector accepts bal-
anced microphone inputs for the associated
input channel.
Stereo Input Module
Insert L / Insert R
These ‘combined send & return’ female TRS
jacks are used to insert effects or signal process-
ing into the Left and Right channels of the Stereo
Input module. They can also be used to bring a
signal into the channel, bypassing the input pre-
amp and gain circuit. The return input is enabled
by depressing the channel Insert switch.
Bal Line In L / Bal Line In R
These balanced 1/4" TRS jacks accept balanced
or unbalanced line level inputs, and delivers
them into the associated (Left or Right) selector
switch.
Bal Mic In L / Bal Mic in R
These female XLR connectors accept balanced
microphone inputs, and deliver them into the
associated (Left or Right) selector switch.
Group Module
Group Bal Out
This male XLR jack carries the post-fader output
signal from the associated group module.
Group Ins Send
This balanced 1/4" TRS jack allows for the
group signal to be sent to an effect or signal
processor.
Bal Ins Return
This balanced 1/4" TRS jack allows for the
return of the effected and/or processed group sig-
nal back into the associated group.
Bus In
This female XLR connector delivers the connect-
ed signal directly to the associated group bus.
(Useful for connection of expander mixers)
Matrix Out
This male XLR connector delivers a balanced
signal from the associated matrix.
Matrix Ext In
This balanced female XLR connector is designed
to accept an external signal that is inserted into
the Matrix. This level is controlled by the Matrix
Ext Level control.
Aux In A/B Left/Right
These female XLR jacks (on group modules 5-8)
accept signals controlled by the Stereo Aux in sec-
