The EZ-PA20 is a stereo audio amplifier with one line input and a front-panel volume control. An integral compressor/limiter allows a higher sound output level without clipping than a standard amplifier. The outputs drive 4 or 8 ohm speakers. The EZ-PA20 is used in houses of worship, restaurants, clubs, meeting rooms, educational facilities, conference rooms and commercial sound systems.
