Electrovoice ma-1206 Brochure

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 

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 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.
