4.1.4  AUX SENDS

1–12 These 1/4-in TRS output connectors provide 12 

balanced or unbalanced line-level signals for effects 

devices or stage monitor amplifiers.  

4.1.5  LINE INPUTS 1–8 (RETURNS)

These 1/4-in TRS input connectors accept eight bal-

anced or unbalanced line-level signals from an external 

processor or other device. They can be used as addi-

tional line inputs or as aux returns. The LINE INPUTS 

appear on channels 1–8 on the RETURNS bank.  

4.1.6 MONITOR 

These 1/4-in TRS output connectors provide three 

balanced line-level signals that can be used to provide 

another stereo (

L

, 

R

 outputs) or mono (

M

 output) main 

mix output or to monitor the 

CD/TAPE A

 or 

CD/TAPE 

B

 inputs. See MONITOR SOURCE on page 49 for more 

information. 

Connect these outputs to the inputs of an amplifier, 

powered speaker, or recording device. Typically, the 

L

and 

R

 outputs are connected to active studio monitors 

and the 

M

 output to an active floor wedge. 

4.1.7 CD/TAPE A IN/OUT 

These RCA jacks connect to the inputs and outputs of 

a CD/tape device. The TAPE IN jacks accept an unbal-

anced signal from a tape recorder or other signal source 

using standard consumer audio RCA cables. The signal 

can be routed to the MONITOR outputs with 

CD/TAPE 

A

 selected as the source in the MON. SOURCE Touch-

screen (see page 49). This allows cueing intermission 

music through the MONITOR or PHONES outputs. 

The 

CD/TAPE A

 inputs can also be routed to the 

MAINS OUT

 from the STEREO INPUT Touchscreen. 

This allows playing music between sets over the main 

PA speakers. When engaged, the QuickMix Area pro-

vides input level adjustment for CD/TAPE A on a rotary 

encoder. 

WARNING:

 Selecting L/R in the STEREO 

INPUT Touchscreen for the CD/TAPE A input 

can create a feedback path between TAPE IN 

and TAPE OUT. Make sure your tape deck is 

not in record, record pause, or input monitor 

mode, and turn the tape level control all the 

way down. 

The 

CD/TAPE A

 outputs produce an unbalanced signal 

that is tapped off the 

MAINS OUT

. Normally, these are 

connected to the inputs of a recorder, but they can be used 

as two additional main outputs (i.e., for another zone). 

4.1.8 CD/TAPE B Input 

These 1/4-in TRS input connectors accept balanced 

or unbalanced line level signals from the outputs of a 

CD/tape player or virtually any stereo line-level source. 

The 

CD/TAPE B

 input can be routed to the 

MAINS 

OUT

 from the STEREO INPUT Touchscreen (see page 49). 

This allows adding the signal to the 

MAINS OUT

 or just 

playing music between sets over the main PA speakers. 

4.1.9 TALKBACK MIC Input 

This female XLR connector accepts an external 

talkback mic input. It requires a dynamic microphone 

because it does not supply phantom power. Use the 

Talkback UTILITY Touchscreen to route the signal to 

the desired outputs (see page 49). 

4.1.10 MAINS OUT 

These male XLR connectors provide balanced, line-

level signals representing the end of the processing 

chain, where the fully mixed music is sent to the amps 

and speakers. 

LEFT

 and 

RIGHT

 connectors output 

the left and right stereo signals, respectively, while the 

CTR/MONO

 connector outputs the center signal (in 

LCR mode) or the mono signal (in L/R+MONO mode).
