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:

Model	Size	Acoustic Design
205	4”	Single Cone
405	4”	Single Cone
209	8”	Single Cone
309	8”	Coaxial
409	8”	Coaxial
Pro-8A	8”	Coaxial

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 set but supplies twice the power at 120 watts. Both models have a variety of features to enable them to be customized to a wide range of background 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.
