PATCHBAY DESCRIPTION

At the risk of stating the obvious, this is
where you plug everything in: microphones,
line-level instruments and effects, and the ulti-
mate destination for your sound: a tape
recorder, PA system, etc. A few of the features
described in this section are on top of the
mixer, but most are out back on the "pod."
1604-VLZ PRO, you can patch anything almost
anywhere, with nary a care. Here's why:
• Every input and output is balanced
(except insert, phones and RCA jacks).
• Every input and output will also accept
unbalanced lines (except XLR jacks).
• Every input is designed to accept virtually
any output impedance.
• The main left and right mix outputs can
deliver 28dBu into as low as a 600 ohm load.
• All the other outputs can deliver 22dBu
into as low as a 600 ohm load.
• All the outputs are in phase with the inputs.
All we ask is that you perform the Level-Setting
Procedure
sound source. So stop worrying and start mixing!

MIC/LINE INPUTS ON EVERY CHANNEL

The original CR-1604 had six mic/line channels
and ten line-only channels. That was fine for most
applications, but live sound users were forced to
go out and buy the XLR-10 mic input add-on
module. No more. Each and every channel on the
New Improved 1604-VLZ PRO has the legendary
Mackie mic/line input circuit. It' s like getting a
free XLR-10 with your mixer!

MIC INPUTS

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

E-Z INTERFACE

Concerned about levels,
balancing, impedances, po-
larity, or other interface
goblins? Don't be. On your
every time you patch in a new
and noise. You can plug in almost any kind of
mic that has a standard XLR-type male mic
connector. Always be sure to perform the
Level-Setting Procedure
nals are routed from these inputs:
wire your own, connect them like this:
SHIELD
SHIELD
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 1604-VLZ PRO's mic inputs will handle
almost any kind of mic level you can toss at
them, without overloading.

PHANTOM POWER

Most condenser mics require phantom power,
where the mixer sends low-current DC voltage to
the mic's electronics through the same wires
that carry audio. The 1604-VLZ PRO's phantom
power is globally controlled by the PHANTOM
switch on the rear panel .
Semipro condenser mics often have batter-
ies to accomplish the same thing. "Phantom"
owes its name to an ability to be "unseen" by
dynamic mics (Shure ® SM57/SM58, for in-
stance) that don't need external power and
aren't affected by it anyway.
Unless you know for cer-
tain it is safe to do so,
never plug single-ended
(unbalanced) micro-
phones, instruments or
electronic devices into the MIC input jacks if
the phantom power is on.
