solution. Situations where cost, tight physical spaces, audio response, local building or fire
codes, etc... come into play may require a unique EV component speaker solution. The EV raw
frame ceiling speaker line consists of 6 models listed below to address nearly every situation:

Typically these speakers are installed with a transformer, grille and back box to complete the
installation. Often times raw frame speakers are used when the installation calls for very unusual
space constraints or where there is a desire to hold costs down to the lowest possible figure.
The installation of raw frame ceiling speakers does require more effort than the tuned sealed
enclosures such as the EVID series. Keep in mind that the audio performance of even the best
component models generally do not equal any of the EVID sealed units because the enclosures
are not tuned and matched to the drivers used.

MA Series Mixer Amplifiers
The MA-1200 series of professional rack
mount mixer/amplifiers are designed for
larger BGM/paging and public address
system installations where expandability and
flexibility is the ticket. These new units are
exceptional values, loaded with features and
are easy to install in a variety of system
designs.
The MA-1206 provides a powerful 60 watts
of output power into 70v/100v or 8 ohm
loads. The MA-1212 has the same feature s
models have a variety of features to enable them to be customized to a wide range of backgroun
music and paging applications.
The units 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 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.
