CR MAIN and CR NEAR FIELD

• Pairs of 1/4" TRS stereo line-level outputs for

sending signals to control room speakers.

• Both outputs carry the same signal (as selected

in the Control Room section).

• Levels can be adjusted independently or

linked together.

• Post-DSP, Master L/R fader, and D/A converter.

• The signal fed to these outputs is selected in

the CONTROL ROOM section of the control
surface.

PHONES 1 and 2

• Each jack carries an unbalanced stereo signal

through a 1/4" TRS jack.

• Designed to connect to virtually any stereo

headphones. Phones 1 and 2 V-Pots adjust to
compensate for headphones with exception-
ally high or low impedances.

• The signal at these outputs is determined by

the PHONES/CUE MIX 1 and PHONES/CUE
MIX 2 source selection on the control surface.

• Aux 9–10, Aux 11–12, or the CONTROL

ROOM selection can feed either or both
Phones/Cue outputs.

• The Master L/R mix can be copied to either or

both Aux 9–10 or 11–12 Cue Mixes.

STUDIO OUT L-R

• Signal at these outputs is determined by the

CONTROL ROOM source selection.

• Balanced analog stereo-paired outputs for

sending signals to the studio.

• 1/4" TRS outputs can drive a balanced or un-

balanced input.

• Level controlled by the V-Pot in the

SOLO/STUDIO section of the control surface,
when STUDIO LEVEL is selected.

PUNCH I/O

• A remote switch connection for activating the

MMC master record function—to punch in or
out of record.

• Use with a normally-open switch.

TALKBACK

• A remote switch connection for engaging the

talkback function.

• Duplicates the Talkback switch in the CON-

TROL ROOM section.

• Use with a normally-open switch.

2 TRACK A, B, and C

• Balanced 1/4" TRS inputs for receiving line-

level analog signals from a 2-track recorder.

• The separate left/right pairs feed the 2 TRACK

A, B, and C buses in the control room monitor-
ing section.

• Can accept balanced and unbalanced signals.

AUX OUT Section

• There are 12 Aux sends available.

• Auxes 1–8 provide mono 1/4" TRS ana-

log line-level outputs.

• Auxes 9 and 10 are linked together as a

stereo pair of 1/4" TRS analog line-level
outputs.

• Auxes 11 and 12 are linked together as

a stereo pair of 1/4" TRS analog line-
level outputs.

Note:

Auxes 1–12 simultaneously feed the

analog Aux sends and the internal effects
cards (by default).

Each MFX card handles two separate

mono inputs, so auxes are paired. MFX
effects returns are stereo, so each card,
while receiving two discrete mono inputs,
returns two sets of stereo outputs to the
EFFECTS Bank. Internally, Aux 1 returns
to FX 1/2; Aux 2 returns to FX 3/4; Aux 3
returns to FX 5/6; continuing through Aux 8,
which returns at FX 15/16.

UFX cards handle 4 mono, two stereo,

or one stereo and two mono inputs.

For each UFX card, no matter what the

Aux input selection, returns appear at the
FX faders numbered the same as their
respective slots.

If all UFX effects are mono, each return

correlates directly to the Slot number ( 9 to 9,
10 to 10, etc.)

• When stereo effects are selected, re-

gardless of the Aux input selection,
returns appear at the FX faders num-
bered the same as their respective slots.
For stereo effects with mono inputs, the
effects return at the respective slot
numbered pair (input 9 returns at FX 9/
10; input 11 returns at FX 11/12, etc.)

Note:

Patching from an Aux output does not interrupt

the internal sends to the FX Cards, so it’s possible to
run both internal and outboard effects at the same time.
