Rear View
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 constant-
voltage 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 Electro-
Voice ® Model MA-606.
