- Inputs: Balanced or unbalanced stereo on a captive screw connector; unbalanced stereo on RCA connectors and a 3.5 mm stereo mini jack
- Speaker outputs: 5 mm captive screw connector
- 15 watts rms per channel into 4 ohms, 8 watts rms per channel into 8 ohms
- Extron Patented CDRS¢â - Class D Ripple Suppression
— CDRS is an Extron Patented technology that provides a smooth, clean audio waveform and an improvement in signal fidelity over conventional Class D amplifier designs. CDRS eliminates the high frequency switching ripple characteristic of Class D amplifiers, a source of RF emissions which can interfere with sensitive A/V equipment such as wireless microphones.
- Front panel bass, treble, and input level controls
- UL 2043 plenum rated
— The MPA 152 meets UL 2043 for smoke and heat release for installation within a plenum airspace above a drop ceiling - power supply excluded. Above-the-ceiling placement conceals the amplifier to prevent theft, and is convenient for installing equipment when space inside the room is limited.
- Balanced and unbalanced buffered audio inputs
— Accepts balanced or unbalanced audio input signals on a captive screw connector, and unbalanced audio on both RCA connectors and a 3.5 mm stereo mini jack. The three inputs are individually buffered, and can be connected to three separate sources at the same time without altering performance.
- Fanless design
— The MPA 152 does not require fans or vents for cooling, ensuring quiet, reliable operation.
- Automatic clip limiter
— Detects actual onset of clipping by comparing input and output waveforms. Gain is automatically reduced with a slow attack and fast release to eliminate clipping. This advanced limiter design protects the speakers from clipping distortion and offers superior sonic characteristics compared to limiters that use signal compression.
- Remote volume and mute control port
— In basic installations without control systems, this port allows the MPA 152 to be remotely controlled using the optional Extron VCM 100 analog volume and mute controller or VC 50 analog volume controller.
- Rack-mountable 1U, quarter rack width metal enclosure
- External universal power supply included, part # 70-380-01
— Provides worldwide power compatibility.
