Mackie LM-3204E, LM-3204 User Manual
32x2x2 STEREO LINE MIXER
The
LM-3204 Line
Mixer combines exceptional sound quality
with up to forty lmono ine
inputs in five rack spaces.
It features sixteen stereo
(16x2) inputs plus four
stereo (4x2) AUX returns.
Additional inputs can be
added in multiples of 16
stereo channels with the
LM-3204E Expander unit.
Proven Mackie
features in a line
mixer configuration.
Naturally, the LM-32 04
has our CR-1604 and Micro Series 1202's best
points: luxurious headroom, Unity gain structure,
+4dBu internal operating
levels, intuitive layout and
in-depth metering. It has
our 3-band equalization at
musically useful points:
12kHz shelving treble for
more sizzle, instead of the
conventional 10kHz. 2.5Hz
peaking midrange. And
80Hz bass instead of
100Hz.
It has our
“four buses in a 2-bus
board” ALT 3-4 feature.
ALT 3-4 gives you an extra
stereo output that each
channel can be assigned to
at the touch of a button.
The LM-3204 shares the
same Mackie Mix Amp architecture as our proven
CR-1604 and MicroSeries
1202. Like our other compact mixers, it is designed
to handle hot inputs on all
channels without exhausting headroom.
Two mic preamps.
Even though the
LM-3204 is a line mixer ,
we wanted to increase its
utility in live applications.
So we added two of our
proven mic preamplifiers, a
design well known for its
high headroom and ultralow noise. Both mic
preamps have trim controls, balanced XLR inputs
and 1/4" outputs. The outputs can be patched into
7/1/95

New monitor and
tape features
The LM-32 04 also introduces new features that
provides real flexibility for
both live and studio applications.
It has separate Control
Room and Phone moni-
toring outputs, each with
its own level control. Monitoring controls consist of a
stereo Control Room fader,
the Phones level control
(with a handy Phones jack
just below it), and the Tape
Monitor switch. Control
Room and Phone monitor
outputs always share the
same sources:
■ The main Left and Right

conditions;
■ The output of your tape
