 MONITOR

Point Before: 

INSERT 

(

HEADPHONES

.

Point After: Balanced or unbalanced cable
with 

1

4

" TRS or TS connector.

Patch these outputs to an amp’s inputs, and

patch the amp’s outputs to speakers mounted
at the console. Alternatively, the 

MONITOR

outputs can deliver the FOH (front-of-house)
headphone mix to an engineer operating a
secondary stage monitor console.

If you want to drive several pairs of head-

phones via an outboard amplifier, patch these
outputs to that amp.

If the console is in a soundproof room, as in

live sound-studio work or studio recording/mix-
down, patch these outputs to your control room
amplifier and speakers. Be aware: the intercom
signals 

 do not appear at these jacks.

 TALKBACK

Point Before: 

ASSIGN 

 (

EXTERNAL

)

Point After: Balanced or unbalanced cable with

1

4

" TRS or TS connector.

If you want the 

TALKBACK 

signal to be

routed somewhere other than the 

AUX SEND

MASTERS

LEFT/RIGHT

 mix, or 

MATRIX A

D

,

patch this output to that device. Similar to the

MONITOR 

outputs, this jack is generally not

required, but can be a lifesaver in unusual
situations.

You can use the 

EXTERNAL 

switch

(

ASSIGN 

) to deliver the 

TALKBACK 

(and

OSCILLATOR

) signal to a second console, such

as a monitor console. Simply patch from the
FOH (front-of-house) console’s 

TALKBACK 

output to a line-level Channel input of the
monitor console. Then use that Channel’s 

AUX

sends to deliver the 

TALKBACK 

signals to the

stage monitors.

 TALKBACK MIC INPUT

Point Before: Balanced microphone-level cable
with male XLR connector (pin 2 = hot, pin 3 =
cold, pin 1 = shield). This connector has 48-volt
phantom power permanently engaged.

Point After: 

TALKBACK 

section 

.

Patch one dynamic or condenser microphone

to either jack to enable the 

TALKBACK 

func-

tions (there is no built-in microphone). The two
phantom-powered jacks are wired in parallel,
feeding a balanced mic preamp, then controlled
by the 

TALKBACK LEVEL 

 control.

Since these jacks are wired in parallel, only

one should be used at a time.
