Description

The Electro-Voice MA series of mixer-amplifiers are available with output
power ratings of 60 (MA-1206) or 120 (MA-1212) watts. The MA series
products provide background music and allow paging in environments
such as churches, small businesses, and professional offices.
The MA inputs include 10 combination balanced or unbalanced
Microphone/AUX level connections, 2 stereo AUX summing inputs,
telephone paging and Power Amp In connections. Inputs to Mic 1 can
be set to automatically mute the other Mic and AUX level input channels.
Input sources to Aux 1 and 2 may include: tape players, compact-disc
players, AM/FM tuners, mixer-preamplifiers or wireless microphones.
The telephone paging input accepts the signal from a standard 600 ohm
paging line.
The Power Amp In jack, along with the Preamp Out jack, is provided to
insert an equalizer or other signal processing device before the power
amplifier.
The amplifier includes protection circuitry to prevent damage from either
open or shorted speaker lines.
An adjustable automatic muting circuit mutes all other inputs when the
paging input is activated.
