Digital 8•Bus Description
the BUS 1–8 Masters (Fader Bank 4). The Bus
Outputs are also used for surround-sound
mixing. See Appendix F for the pin-out diagram
for the Bus 1–8 25-pin D-Sub connector.
Analog XLR L-R MASTER OUTputs
These are the main left and right outputs.
They are balanced analog XLR output
connectors, fed post-DSP, fader, and DAC.
These outputs are driven by the main L-R bus.
Analog TRS L-R MASTER OUTputs
These connectors are two 1⁄4" TRS stereo
line-level outputs for sending signals to control
room speakers. They are balanced analog
stereo-paired outputs fed post-DSP, fader, and
DAC. The signal at this output is the same as
the CR ALT output, but with independent level
control, and is determined by the Control Room
Source selection. These outputs can drive a
balanced or unbalanced input.
CR MAIN L-R Outputs
These connectors are two 1⁄4" TRS stereo
line-level outputs for sending signals to control
room speakers. They are balanced analog
stereo-paired outputs fed post-DSP, fader, and
DAC. The signal at this output is the same as
the CR NEAR FIELD output, but with indepen-
dent level control, and is determined by the
Control Room source selection. These outputs
can drive a balanced or unbalanced input.
CR NEAR FIELD L-R Outputs
These connectors are two 1⁄4" TRS stereo
line-level outputs for sending signals to control
room speakers. They are balanced analog
stereo-paired outputs fed post DSP, fader and
DAC. The signal at this output is the same as
the CR MAIN output, but with independent
level control, and is determined by the Control
Room source selection. These outputs can
drive a balanced or unbalanced input.
PHONES 1 and 2 Outputs
These are unbalanced 1⁄4" TRS jacks
for connecting stereo headphones. The
TRS jacks are wired as follows:
Tip = Left output
Ring = Right output
Sleeve = Shield (audio ground)
These outputs are designed to drive virtually
all stereo headphones. The signal at these
outputs is determined by the PHONES/CUE MIX
1 and 2 source selection. Adjust the Cue Mix
LEVEL control to compensate for headphones
with exceptionally high or low impedances.
STUDIO L-R OUTputs
These connectors are two 1⁄4" TRS stereo
line-level outputs for sending signals to the
studio. They are balanced analog stereo-paired
outputs fed post-DSP, fader, and DAC. The
signal at these outputs is determined by the
Control Room source selection. These outputs
can drive a balanced or unbalanced input.
PUNCH I/O
This connector is for a remote punch-in/
punch-out switch. Use a normally-open switch.
TALKBACK
This connector is for a remote talkback
switch. It duplicates the Talkback switch in the
Control Room Section. Use a normally-open
switch.
2 TRACK A, B, and C L-R Inputs
These are balanced 1⁄4" TRS jacks for
connecting line-level input signals from a
2-track recorder. The separate left/right pairs
feed the 2 TRACK A, B, and C buses in the
control room monitoring section. These inputs
can accept balanced and unbalanced signals.
AUX Outputs
There are eight mono and two stereo-pair
TRS, line-level, balanced auxiliary outputs.
Aux Outputs 1 and 2 are analog outputs
paralleled with the internal effects send buses
1 and 2 respectively. AUX outputs 3 through 8
are independent analog mono outputs, fed from
the corresponding internal aux buses. AUX
outputs 9 through 12 are analog stereo pair
outputs. Auxes 9–10 constitute a single left/
right pair and Auxes 11–12 constitute a single
left/right pair. These outputs can drive a
balanced or an unbalanced input.
When Aux 9–10 is selected as a Cue Mix
source, aux outputs 9 and 10 are paralleled with
the Cue Mix source from the internal aux buses
9 and 10. The same principle applies when Aux
11–12 is selected as a Cue Mix source.
