MS1402-VLZ PATCHBAY DESCRIPTION
At the risk of stating the obvious, this is
where you plug everything in: microphones,
line-level instruments and effects, head-
phones, and the ultimate destination for your
sound: a tape recorder, PA system, etc.
MIC INPUTS (Channels 1–6)
We use phantom-powered, balanced micro-
phone inputs just like the big studio
mega-consoles, for exactly the same reason:
This kind of circuit is excellent at rejecting
hum and noise. You can plug in almost any
kind of mic that has a standard XLR-type male
mic connector. To learn how signals are
routed from these inputs:
own, connect them like this:
Pin 1 = Ground or shield
Pin 2 = Positive (+ or hot)
Pin 3 = Negative (– or cold)

Professional ribbon, dynamic and condenser
mics will all sound excellent through these in-
puts. The MS1402-VLZ's mic inputs will handle
any kind of mic level you can toss at them,
without overloading. Be sure to perform the
Level Setting Procedure:

PHANTOM POWER

Most modern professional condenser mics
are equipped for Phantom Power, which lets
the mixer send low-current DC voltage to the
mic's electronics through the same wires that
carry audio. (Semi-pro condenser mics often
have batteries to accomplish the same thing.)
"Phantom" owes its name to an ability to be
"unseen" by dynamic mics (Shure SM57/SM58,
for instance), which don't need external power
and aren't affected by it anyway.
The MS1402-VLZ's phantom power is glo-
bally controlled by the PHANTOM switch on
the rear panel

Do not plug instrument outputs into the
MIC IN jacks with PHANTOM power on unless
you know for certain it is safe to do so.
