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:

. To wire

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

" jacks are usually patched to the in-

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.

It’s that easy.
