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: compressor, lim-
iter, graphic equalizer. 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
(AUX 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.

AUX RETURN INPUTS

This is where you connect the outputs of your
parallel effects devices (or extra audio sources).
They'll accept just about any pro or semipro
effects device on the market. To learn how sig-
nals are routed from these inputs:
your own cables: .

Mono: If you have an effects device with a
mono output (one cord), plug that into L in-
put of an AUX 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.

SUB OUTS

These
puts of a multitrack deck, or to secondary
amplifiers in a complex installation. To learn
how signals are routed to these outputs:
To wire your own cables:
Double Busing
How on earth do you get four jacks to
feed eight tracks? To feed an 8-track deck
with only four SUB OUTS, simply use four
Y-cords:
• SUB OUT 1 feeds tracks 1 and 5
• SUB OUT 2 feeds tracks 2 and 6
• SUB OUT 3 feeds tracks 3 and 7
• SUB OUT 4 feeds tracks 4 and 8
Tracks in record mode will accept the signal,
and tracks in safe mode will ignore the signal.
. To wire
It's that easy.
