CONGRATULATIONS! You have purchased the
Shure Model 1200 Powermixer, the finest compact
mixer-amplifier available today.
The Model 1200 Powermixer includes a flexible
microphone mixer with six inputs for high- or
low-
impedance sources and a 200-watt power amplifier.
The 1200 is human engineered for ease of setup and
operation. Connection of microphones and other
equipment (tape recorder, equalizer, effects device,
remote amp) is fast and convenient.
The AUDIOMASTER
System,
consisting of the Model
1200 Powermixer and Model 3200
Loudspeaker(s),
works equally well for sound reinforcement or record-
ing of music, vocals, or speech.
The Model 1200 Powermixer is rack-mountable or
portable; a high-power,
&input mixer-amplifier, ex-
pandable to 8 or 10 inputs, with famous Shure versa-
tility and ruggedness. Inputs to the Powermixer accept
both high- and low-impedance microphones as well
as amplified instruments or other high-level sources.
Individual
Input Attenuation controls, with overload
indicators, are continuously adjustable to prevent
input overload. The Powermixer has bui It-in rever-
beration with individual channel and overall level
adjustments. Other effects devices or an equalizer
are easily connected via a post-Master control pro-
gram loop. An integral power amp Limiter prevents
overload distortion over a wide input signal range.
Pre-Volume Monitor send controls and a pre-Master
Volume Tape Output provide maximum usefulness
in performance or recording applications. The con-
trol panel is human-engineered with color-coded
knobs for error-free adjustments while LED readouts
give instant visual notice of overload and operating
status.
The Model 3200 two-way, time-corrected loudspeaker
is a high-power unit designed to be compatible with
the Model 1200 Powermixer. A wide-range frequency
response and excellent sound quality suit it for a
great variety of performance and public-address
situations.
The
AUDIOMASTER System gives you outstanding
sound capability; it's maximally versatile and port-
able, and it's backed by Shure's traditional quality
and reliability.
