STEREO LINE INPUTS (Channels 7–8,
9–10, 11–12 and 13–14)
These fully balanced inputs are designed for
stereo or mono, balanced or unbalanced sig-
nals, from –10dBV to +4dBu. They can be used
with just about any professional or semi-pro in-
strument, effect or tape player. To learn how
signals are routed from these inputs:
wire your own cables: .
In the stereo audio world, an odd-numbered
channel usually receives the "left signal." For
example, you would feed the MS1402-VLZ's
line inputs 7–8 a stereo signal by inserting the
device's left output plug into the Channel 7
jack, and its right output plug into the Chan-
nel 8 jack.
When connecting a mono device (just one
cord), always use the Left (MONO) input and
plug nothing into the Right input — this way
the signal will appear on both sides. This trick
is called "jack normalling" .

PARALLEL?
the terms "serial" and "paral-
lel" around like hacky sacks.
Here's what we mean by them.
"Serial" means that the entire signal is
routed through the effects device. Examples:
compressor/limiters, graphic equalizers. Line-
level sources can be patched through a serial
effects device before or after the mixer or,
more conveniently, through the channel insert
jacks located on the rear of the mixer (INSERT
SEND/RETURN) .
"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. (See diagrams below.)
