Mackie MS1202 Specification

12x2 MICRO SERIES MIC/LINE MIXER

The
MicroSeries
1202 delivers the
same high performance
electronics and rugged all­steel construction as its big
brother, the CR-1604. Same
high-headroom and low
noise mic preamplifiers.
Same overall dynamic range.
Same rugged steel construc­tion with built- in power
supply, thru-hole-plated
fiberglass circuit boards,
gold-plated interconnects
and sealed rotary controls.

The result is a rare combi­nation of performance and
reliability in a small, very
affordable mixer that is well
suited to serious permanent
installation, video and mo­bile recording applications.

Big mixer features in

less than one

square foot of space

The MicroSeries 1202
mic/line mixer has:

• A working signal-to-noise

ratio of 90dB, distortion
below 0.009% across the

nal dynamic range (that’s
26dB better than digital!)

• Switchable phantom-

powered mic inputs with
discrete, balanced micro­phone preamps as good or
better than those found in
big consoles. Four conju­gate-pair transistors with
large-emitter geometry re­duce distortion at all levels,
while delivering extremely
low noise (–129.5 dBm
@150 ohms, 20Hz-20kHz,
with over a 300K band­width).

• Four mono channels

(each featuring discrete
front-end mic preamp/line
input) and four stereo input
channels (each with sepa­rate left and right line
inputs).

• Pan control on every
channel.

• Low-frequency EQ at
80Hz, high-frequency EQ at
12kHz.

• Two AUX sends per
channel with up to 15dB
available gain above Unity.

• A master section with
stereo AUX returns, separate
headphone level control and
metering (also with separate
left and right line inputs).

• Unity gain is easily
found with the center detent

provided on all front panel
gain controls.

• Three-in-one channel
metering display. Normally
the meters show main L/R
output. But when you press
the metering button, the left
array displays mic preamp
operating levels and the right
channel shows channel op­erating levels. This allows you
to set and meter actual levels
instead of having to rely on a
single overload LED.

• RCA/phono-type tape
inputs and output connec­tors with tape input available

through AUX Return 2, via
a TAPE IN switch.

• Line inputs and outputs
are designed to work with
any line level, from instru­ment level, to semi-pro
–10dB, to professional +4dB
levels. The main outputs
operate either balanced or
unbalanced, as required.

• While not specifically
designed for rack mount­ing, “dumbo ear” rack
flanges are available for the
1202, turning it into a 7­space rack mount mixer.

Built like a brick.

Like its big brother, the
CR-1604, the MicroSeries
1202 has been designed by
Greg Mackie, a 20-year pro
audio veteran. All his designs
are intended for non-stop,
24-hour-a-day professional
duty in broadcast and per­manent PA applications, TV
and radio stations and post­editing suites where nothing
must ever go wrong. The
1202 is no exception.

For example, it has sealed,
co-molded rotary controls
instead of open-frame phe­nolic potentiometers that
can suffer from airborne
dust and contamination. For
the life of an installation, the
1202 provides minimal rota­tional contact noise (and if
there ever is a problem, pots
are individually replaceable).
Plus, our combination of
mounting, co-molding and
energy-absorbing knob
design helps prevent
impact damage.

Along with its steel chas­sis and through-hole-plated
fiberglass circuit boards, the
MicroSeries 1202 also fea-

tures a built-in power supply
instead of a “wall wart” or
“line lump.” Not only does this
eliminate the inevitable
hassles of dealing with exter­nal power supplies, but also
actually reduces hum. The
tiny transformers inside “line
lumps” are typically driven
into non-linearity (in excess of
15 kiloGauss) to provide
enough power for the mixer.

This creates stray 25- to 35µV

magnetic fields that are easilty
picked up by shielded audio
cables. The MS1202’s internal
transformer loafs along at un­der 10 kiloGauss, reducing

stray fields to less than 1µV.

The MS1202 also uses the
same RF protection circuitry
and construction as the
CR-1604, making it virtually
impervious to RF interference
in high-energy environments.

Multiple applications

Frankly, the MicroSeries
1202 is so reasonably priced
that it initially may be hard to
take seriously. But thousands
of professionals DO take the
1202 seriously enough to rely
on it day-in and day-out.

We receive a steady stream of
warranty cards from TV and
radio stations, video produc­tion houses, touring sound
companies, big-studio
engineers and corporate in­house A/V departments (see
examples at right).

Why? Because the
MicroSeries 1202 is able to
perform in applications
where other small mixers
don’t measure up:

•Audio mixer for video post

editing suites

•Impedance or level

matching “tool kit”

•Headphone or cue mixer

•Effects sends submixer

•ENG mixer

•Broadcast remote mixer

•8-track monitor mixer

•Live film and video

sound mixer

•AUX inputs for a larger

console

No matter what your
application, you can’t go wrong
with a Mackie MicroSeries

11.470"

1202. If you simply want the
best possible mixer in the least
amount of space, there can
only be one choice. If cost is
an issue, this is the best price­to-performance mixer
available. If durability and free­dom from call-backs are
critical, the MS1202’s construc­tion—and track record —speak
for themselves.

Only one mixer model puts
so many good things into such
a small package… the Mackie
Designs MicroSeries 1202.
