Electro-Voice MA-1212 Brochure

MA-1212
The MA series of professional rackmount
mixer/amplifiers are designed for background
music/paging and public address system
installations where expandibility and flexibility is
the ticket. These units are exceptional values,
loaded with features and are easy to install in
a variety of system designs.
The MA-1206 and MA-606 provide 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. All models
have a variety of features to enable them to be
customized to a wide range of background music
and paging applications.
The MA-1212 and MA-1206 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
MA-606
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.

MA Series of EV Professional Mixer/Amplifiers
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 MA-606 incorporates all of the features of
the MA-1206 and MA-1212 but provides four
combination balanced mic/line inputs and two
stereo summing inputs which makes the unit ideal
for smaller installations.
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.
• 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.
