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. See page 26 for
details of the AUX RETURN level controls.
Serial Device (e.g., Compressor)
Parallel Device (e.g., Reverb)
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

1
These / " jacks are usually patched to the in-
4
puts of a multitrack deck, or to secondary
amplifiers in a complex installation. See page
22 for details of the SUBGROUP FADERS
Double Busing
How on earth do you get four buses to
feed eight tracks? Double busing!
• Bus 1 feeds SUB OUT 1 and SUB OUT 5,
which in turn feed tracks 1 and 5
• Bus 2 feeds SUB OUT 2 and SUB OUT 6,
which in turn feed tracks 2 and 6
• Bus 3 feeds SUB OUT 3 and SUB OUT 7,
which in turn feed tracks 3 and 7
• Bus 4 feeds SUB OUT 4 and SUB OUT 8,
which in turn feed tracks 4 and 8
Tracks in record mode will accept the signal,
and tracks in safe mode will ignore the signal.
