Insert; Aux Returns - Mackie 1202 VLZ Owner's Manual

CHANNEL INSERT
(Channels 1–4 )
These jacks, on the back
of the MicroSeries 1202-VLZ,
are where you connect serial
effects such as compressors, equalizers, de-
essers, or filters . Since most people don't
have more than a few of these gadgets, we've
included inserts for just the first four chan-
nels. If you want to use this kind of processing
on channels 5 through 12, simply patch
through the processor before you plug into the
MS1202-VLZ.
The CHANNEL INSERT points are after the
TRIM and LOW CUT controls, but before the
channel's EQ and GAIN controls. The send
(tip) is low-impedance (120 ohms), capable of
driving any line-level device. The return (ring)
is high-impedance (over 2.5k ohms) and can
be driven by almost any device.
Insert cables must be wired thusly:
ring
(TRS plug)
tip sleeve
This plug connects to one of the
mixer's Channel Insert jacks.
Tip = Send (output to effects device)
Ring = Return (input from effects device)
Sleeve = Common ground (connect shield to
all three sleeves)
Besides being used for inserting external
devices, these jacks can also be used as chan-
nel direct outputs; post-TRIM, post-LOW CUT,
and pre EQ. In fact, Mackie mic preamps have
become so famous that people buy these mix-
ers just to have four of these preamps in their
arsenal. Here's three ways you can use the
CHANNEL INSERT jacks:
MONO PLUG
Direct out with no signal interruption to master.
Insert only to first "click."
MONO PLUG
Direct out with signal interruption to master.
Insert all the way in to the second "click."
STEREO
PLUG
For use as an effects loop.
(TIP = SEND to effect, RING = RETURN from effect.)

AUX RETURNS

This is where you connect the outputs of
your parallel effects devices (or extra audio
sources). These balanced inputs are similar to
the stereo LINE IN inputs
Sends, Pan, Mute, and Solo). The circuits will
handle stereo or mono, balanced or unbalanced
signals, either instrument level, –10dBV or
+4dBu. They can be used with just about any
pro or semipro effects device on the market.
To learn how signals are routed from these
inputs, see
unplugged. That way, the unused AUX RE-
TURN 2 level control can be used to feed
AUX RETURN 1 to your stage monitors, via
the EFX TO MONITOR switch
Mono Device: If you have an effects de-
SEND to processor
"tip"
vice with a mono output (one cord), plug
that into STEREO AUX RETURN 1, LEFT/
MONO, and leave AUX RETURN 1, RIGHT,
"ring"
RETURN from processor
unplugged. That way the signal will be sent
to both sides, magically appearing in the
center as a mono signal. This won't work
with AUX RETURN 2 — you'll need a Y-cord.
