Electro-voice MA-1206, MA-1200 BROCHURE
The MA-1200 series of professional rackmount
mixer/amplifiers are designed for larger
background music/paging and public address
system installations where expandibility 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.
• 10 balanced mic or line inputs – all available
with 24v phantom power!
• 2 auxiliary stereo summing inputs with 4 level
sensitivity adjustment.
• 60 or 120 watt models available.
• Balanced line level output for adding additional
power amplifiers.
• 24 volt powered operation available for
emergency power requirements.
• Adjustable level telephone paging input.
• Independently adjustable low power
monitor output.
• Integrated “rack ears” allow for rack mounting
without additional accessories.
