The EZ-MXA20 is a stereo mixer amplifier with one mic input and two line inputs. Bass and treble tone controls are included. An integral compressor/limiter allows a higher sound output level without clipping than is possible using a standard amplifier. The output drives 4 or 8 ohm speakers. The EZ-MXA20 is used in houses of worship, restaurants, clubs, meeting rooms and commercial sound systems.
