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 functions (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. 25 DIRECT OUT INSERT SEND INSERT RETURN LINE IN SUB 1 SUB 5 SUB OUTPUTS SUB SUB 2 3 SUB SUB 6 7 SUB 4 SEND SUB INSERTS (BAL/UNBAL) 1 RETURN SEND 5 RETURN SEND 2 RETURN SEND 6 RETURN SUB 8 SEND 3 RETURN SEND 7 RETURN SEND 4 RETURN SEND 8 RETURN MIC 25 DC POWER IN (MACKIE 400-WATT POWER SUPPLY !)

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.
