INSERT (Channels 1–6)
These jacks, on the back of the 1402-VLZ
PRO, 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 six channels. If you want to use this
kind of processing on Channels 7–14, simply
patch through the processor before you plug
into the 1402-VLZ
PRO.
The INSERT points are after the TRIM and
LOW CUT controls, but before the channel’s
EQ and FADER controls. The send (tip) is
low-impedance (120 ohms), capable of
driving any 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:
“tip”
this plug connects to one of the
mixer’s Channel Insert jacks.
“ring”
tip
ring
sleeve
SEND to processor
RETURN from processor
(TRS plug)
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. Check out the 4-track hookup dia-
gram . Here’s three ways you can use the
INSERT jacks:
Direct out with no signal interruption to master.
Insert only to first “click.”

Direct out with signal interruption to master.
Insert all the way in to the second “click.”
For use as an effects loop.

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 inputs without EQ, Aux
Sends, Pan, Mute, and Solo. The circuits will
handle stereo or mono, balanced or unbal-
anced signals, either instrument level, –10dBV
or +4dBu. They can be used with just about
any pro or semi-pro effects device on the mar-
ket.
To learn how signals are routed from
these inputs, see .
One Device: If you have
just one parallel effects
device, use
AUX RETURN
1 and leave AUX
RETURN 2 unplugged.
That way, the unused AUX RETURN 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-
vice with a mono output (1 cord), plug that
into
AUX RETURN 1 LEFT and leave AUX
RETURN 1 RIGHT 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 to feed the L/R bus. In
short,
AUX RETURN 1 uses jack normalling.
AUX RETURN 2 does not use jack normalling.
