Product Details - The Extron MPA 122 Integrated Mini Power Amplifier provides stereo amplification for speaker systems in classrooms and other applications requiring compact, economical audio solutions. It is an ideal step-up from a basic classroom system utilizing built-in video projector speakers. The MPA 122 delivers 11 watts rms per channel into 4 ohms and 7 watts rms into 8 ohms. It is optimized for driving four 8 ohm ceiling speakers, two in parallel per channel.

The MPA 122 accepts balanced and unbalanced stereo inputs, and provides outputs as stereo or dual mono audio signals. Front panel controls are provided for bass, treble, and input level. The front panel also features switches for stereo/dual mono operation and a clip limiter switch which automatically reduces the gain to prevent distortion or amplifier clipping. The MPA 122 features remote control capability for volume adjustment and muting.

• Inputs: Balanced or unbalanced stereo on a captive screw connector; unbalanced stereo on RCA connectors and a 3.5 mm stereo mini jack
