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:
. To
wire your own cables:
.
In the stereo audio world, an odd-numbered
channel usually receives the “left signal.” For
example, you would feed the 1402-VLZ
PRO’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”
.
EFFECTS: SERIAL OR
PARALLEL?
The next two sections toss
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.)
