The EZ-MPA2 is a stereo microphone preamplifier with front-panel volume controls and audio level metering. A front-panel switch engages audio compressors to control overloads and clipping during high level audio bursts or peaks from the microphones. Dynamic or condenser microphones are both supported with rear-panel switchable phantom voltage. The line output is available on RCA or MINI jacks. Left and right channel LED VU metering facilitates easy level adjustment. The EZ-MPA2 is ideal to add microphone inputs to mixers and amplifiers with line inputs. It is used in houses of worship, restaurants, clubs, meeting rooms, educational facilities, conference rooms, studios and commercial sound systems.
