Radio Design Labs EZ-MPA1
Mic Preamp with Compressor, Stereo Output

EZ-MPA1

The EZ-MPA1 is a microphone preamplifier with front-panel volume control and audio level metering. A front-panel switch engages an audio compressor to control overloads and clipping during high level audio bursts or peaks from the microphone. Dynamic or condenser microphones are both supported with rear-panel switchable phantom voltage. The preamplified mic signal feeds both channels of the line output on RCA or MINI jacks. LED VU metering facilitates easy level adjustment.

The EZ-MPA1 is ideal for adding 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. Power supply included.
