MA-1200 Series Mixer/Amplifier Sales Guide
The MA-1200 series of professional rack mount mixer/amplifiers are designed for larger BGM/paging
and public address system installations where expandability and flexibility is the ticket. These new
units are exceptional values, loaded with features and are easy to install in a variety of system designs.
The MA-1206 provides a powerful 60 watts of output power into 70v/100v or 8 ohm loads. The MA-
1212 has the same feature set but supplies twice the power at 120 watts. Both models have a variety
of features to enable them to be customized to a wide range of background music and paging
applications.
The units feature 12 separate input channels. Input channels 1-10 are designed to be used as either
balanced or unbalanced low-Z microphone inputs or they can be switched to a line level signal.
Phantom power is also available on any of the 10 inputs. A signal appearing at input 1 will
automatically mute the other channels unless the mute function is defeated via a switch on the front
panel. Inputs 11 and 12 are for auxiliary line-level sources such as tape or CD players. Mono or stereo
signals may be applied to inputs 11 or 12. The left and right components of a stereo signal can be
applied to the dual RCA phono jacks of these inputs and mixed together to drive the built-in monaural
power amplifier. A rear panel paging input with gain control is provided for the paging output of a
telephone system. An audio signal appearing at this input automatically mutes all other inputs.
A preamplifier output jack and power amplifier input jack permit the mixed output to be fed to an
external signal processor (graphic EQ or compressor), and then returned to the built-in amplifier. The
preamp output may be used to drive an additional power amp with its own set of speakers without
interrupting the function of the built-in amplifier.
The speaker output is available at a barrier strip which includes terminals for driving low impedance
loudspeaker loads, as well as 25, 70.7 or 100 volt distributed systems.
