General Description:

The Electro-Voice ® MA-606 is a 60-watt, six-input mixer
amplifier designed for commercial sound applications. It
features six separate input controls which can be used to
adjust the level from any of 6 input sources.

Input channels 1-4 are designed to either be used as low­Z balance microphone or line level inputs. The combination
connector on inputs 1-4 permits use of either XLR or ¼”
input connectors. A signal appearing at either input 1 will
automatically mute the other channels unless the mute
function is defeated via a switch on the rear panel.

Inputs 5 and 6 are for auxiliary line-level sources such as
tape or CD players. Mono or stereo signals may be applied
to inputs 5 or 6. 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.

There is also a 24v dc power option to operate the unit off
of a 24v emergency power source. 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.

Architects’ and Engineers’ Specifications:

The mixer amplifier shall have six input channels, with individual mix gain controls. Input channels 1 through 4 shall be configured
for either low-Z balanced microphone operation or hi-Z line level signals via switches on the rear panel. A signal present channel 1
shall trigger the muting of channels 2-6. The mute circuit shall be defeatable using a switch on the rear panel. Inputs 1 - 4 shall be
available via combination female XLR / ¼” connectors. Inputs 5 and 6 shall accept either monaural or stereo sources. If a stereo
source is connected, it shall be properly mixed to mono via a resistor network mounted on the input plate. There shall be a paging
input that accepts a 600-ohm line-level feed from a phone system. When a signal is present at the paging input, it shall automatically
mute other input sources. The paging input shall be equipped with its own gain control. There shall be a master level control.
Separate bass and treble equalization controls shall be provided. The mixer amplifier shall meet the following performance criteria:
output power shall be 60 watts; total harmonic distortion shall be less than 1% at 1 kHz; frequency response shall be within ±3 dB
from 50 Hz to 15 kHz; input impedance shall be 600-ohms (balanced inputs) or 47 kW (unbalanced inputs); nominal load impedance
shall be 4-, 8- or 16-ohms for voice-coil-connected loudspeakers, 25, 70.7 or 100-volt nominal transformer windings for the constant­voltage output.

In addition to a preamplifier output/power amplifier input link, there shall also be a line-level balanced XLR output. The mixer
amplifier shall operate from either a standard 120 V ac 50/60 Hz or a 24V dc power source , and measure 13.3 cm (5.2 in.) high x

48.0 cm (18.9 in.) wide x 32.0 cm (12.6 in.) deep. The net weight shall be 8.5 kg (19.0 lb). The mixer amplifier shall be the Electro­Voice ® Model MA-606.
