8. Sub Outs
These four 1/4" jacks are usually patched to
the inputs of a multitrack deck, or to secondary
amplifiers in a complex installation. To learn how
signals are routed to these outputs, see subgroup
faders [38], page 18. (See also the discussion on double
busing on the previous page.)
9. CR Outs (Control Room Outputs)
These 1/4" jacks are usually patched to the inputs of
a control room amplifier or a headphone distribution
amplifier. To learn how signals are routed to these
outputs, see ctl room/phones [43].
10. Phones Out (On Front Panel)
The 1642VLZ4’s stereo 1/4" phones jack will
drive any standard headphone to very loud levels.
To learn how signals are routed to these outputs, see
CR/phones [43] on page 19. If you’re wiring your own
cable for the phones output:
Tip =
left channel
Ring = right channel
Sleeve =
common ground
WARNING:
When we say the headphone
amp is loud, we’re not kidding. It can cause
permanent ear damage. Even intermediate
levels may be painfully loud with some earphones.
BE CAREFUL!
Always turn the CR/phones [43] knob
all the way down before connecting headphones. Keep it
down until you’ve put the phones on. Then turn it up
slowly. Why? “Engineers who fry their ears find them
-
selves with short careers.”
11. Tape Out
These unbalanced RCA jacks tap the main mix
outputs to make simultaneous recording and PA work
more convenient. Connect these to your 2-track
recorder’s inputs. To learn how signals are routed
to these outputs, see main mix [37] fader details
on page 18.
Mono: If you want to feed a mono signal to your tape
deck or other device, simply use the 1/4" mono [15]
output jack.

Y-cord advice: Do not use the stereo “headphone-to-
left/right” splitter adapters. Use the type that send the
same signal to two places; the tip of the source plug
feeds the tips of both destination plugs.
6. Aux Send Outs
These 1/4" jacks usually patch to the inputs of
a parallel effects devices or to the inputs of stage
monitor amps.
To learn how signals are routed to
these outputs, see the Aux discussion on page 21.
Effects: Serial Or Parallel?
You’ve heard us carelessly toss around the terms
“serial” and “parallel.” Here’s what we mean by them:
“Serial” means that the entire signal leaves the mixer
[insert send], is routed through the effects device, and
returns to the mixer [insert return]. Examples: com
-
pressor/limiters, graphic equalizers. Line-level sources
can also be patched through a serial effects device
before or after the mixer.
“Parallel” means that a portion of the signal in the
mixer is tapped off to the device (aux send), processed
and returned to the mixer (stereo return) to be mixed
with the original “dry” signal. This way, multiple
channels can all make use of the same effects device.
Examples: reverb, digital delay.
7. Stereo Returns
This is where to connect the outputs of parallel
effects devices (or extra audio sources). There are
four stereo returns. They’ll accept just about any pro
or semipro effects device on the market. To learn how
signals are routed from these inputs, see stereo return
level [51] on page 22.
Mono: If you have an effects device with a mono
output (one cord), plug that into the left input of
a stereo return and leave the right input unplugged.
That way, the signal will be sent to both sides,
magically appearing in the center as a mono signal.
