7. Stereo Returns

This is where to connect the outputs of parallel 

 

effects devices (or extra audio sources). These 

 

balanced inputs are similar to the stereo line in [2] 

 

inputs (without EQ, aux sends, pan, mute, and solo). 
The circuits will handle stereo or mono, balanced or 
unbalanced signals, either instrument level, –10 dBV 

 

or +4 dBu. They can be used with just about any pro 

 

or semipro  effects  device on the market. The signals 
coming into these inputs can be adjusted using the 
stereo return [40] knobs before passing onto the 

 

main mix bus, see page 19.

One device: if you have just one parallel effects device 

(two cords), use stereo return 1 and leave stereo return 
2  unplugged. that way, the  unused stereo return 2 level 
control can be used to feed stereo return 1 to your stage 
 monitors, via the return to aux 1 [41] switch.

Mono device: if you have an effects device with a 

mono output (one cord), plug that into  stereo return 1, 
l/mono, and leave stereo return 1, right, unplugged. 

 

This way the signal will be sent to both sides, magically 
appearing in the center as a mono signal. This won’t 
work with stereo return 2 — you’ll need a Y-cord.

8. Aux Send 1&2

The aux send [31] knobs tap a portion of each 

 

channel's signal to provide an output here to feed 

 

external parallel effects processors or stage monitoring. 
See the aux send details on page 15.

These 1⁄4" jacks are balanced outputs  capable 

 

of delivering 22 dBu into a 600 ohm balanced or 

 

unbalanced load. 

9. Tape In

These RCA jacks are designed to work with semipro 

as well as pro recorders. To compensate for typically 
low levels, signals coming in here will be automatically 
boosted by 6 dB.

Connect your tape recorder’s outputs here,  using 

standard hi-fi (RCA) cables. 

Use these jacks for convenient tape playback of your 

mixes. You’ll be able to review a mix and then rewind 
and try another pass without repatching or disturbing 
the mixer levels. You can also use these jacks with 

 

a portable CD player to feed  music to a PA system 
between sets.

WARNING:

 Engaging both the tape and  assign 

to main mix  buttons in the control room 
source [33] matrix can create a feedback 

path between tape input and tape output. Make sure 
your tape deck is not in record, record-pause, or input 
monitor mode, when you engage these switches, or 
make sure the control room / submix [34] level knob 

 

is fully counterclockwise (off).

10.  Tape Out

These unbalanced RCA connections tap the main 

mix output to make simultaneous recording and PA 
work more convenient. Connect these to your recorder’s 
inputs. (See also main mix [32] on page 16.)

Mono out: If you want to feed a mono signal to your 

tape deck or other device, simply use an RCA Y-cord to 
combine these outputs. Do not attempt this with any 
other outputs on the 1202VLZ4.

11.  1/4" Main Outs

The 1/4" TRS output connectors provide balanced or 

unbalanced line-level signals. Connect these to the next 
device in the signal chain like an external processor 
(compressor/limiter), or directly to the inputs of the 
main amplifier. These are the same signal that appears 
at the XLR main outputs [13], but 6 dB lower when the 
XLR is used balanced.

To connect balanced lines to these inputs, use a 1⁄4" 

Tip-Ring-Sleeve (TRS) plug, wired as follows:

 

 

Tip = Positive (+ or hot)

 

 

Ring = Negative (– or cold)

 

 

Sleeve = Shield or ground

To connect unbalanced lines to these  inputs, use a 

1⁄4" mono (TS) phone plug, wired as follows:

 

 

Tip = Positive (+ or hot)

 

 

Sleeve = Shield or ground
