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.
