1202-VLZ PRO 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 1–4)
We use phantom-powered, balanced
microphone 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:
. If you wire your
own, connect them like this:
Pin 1 = Ground or shield
Pin 2 = Positive (+ or hot)
Pin 3 = Negative (– or cold)
Professional ribbon, dynamic, and con-
denser mics will all sound excellent through
these inputs. The 1202-VLZ PRO’s mic inputs
will handle any kind of mic level you can toss
at them, without overloading. Be sure to per-
form 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. (Semipro 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 1202-VLZ PRO’s phantom power is glo-
bally controlled by the
PHANTOM
switch on the
rear panel
. (This means the phantom power
for channels 1-4 is turned on and off together.)
Never plug single-ended
(unbalanced) micro-
phones or instruments into
the
MIC
input jacks if the
PHANTOM
power is on.
Do not plug instrument outputs into the
MIC
input jacks with
PHANTOM
power on
unless you know for certain it is safe to do so.
LINE INPUTS (Channels 1–4)
These four line inputs share circuitry (but
not phantom power) with the mic preamps,
and can be driven by balanced or unbalanced
sources at almost any level. You can use these
inputs for virtually any signal you’ll come
across, from instrument levels as low as –40dB
to operating levels of –10dBV to +4dBu, since
there is 40dB more gain available than on
channels
