Page 7: Introduction
(Class D Ripple Suppression) technology that eliminates EMI emissions and interference with sensitive A/V equipment. The design allows the amplifier to be fanless and operate in environments with little or no ventilation. The MPA 401-70V meets UL 2043 for smoke and fire code for above-the-ceiling installations. -
Page 8: Mpa 401-70V Features
D amplifier designs and enables Extron power amplifiers to be situated near wireless A/V devices without RF interference. UL 2043 plenum rated — The MPA 401-70V meets UL 2043 for smoke and heat release for installation within a plenum airspace above a drop ceiling. Above-the- ceiling placement conceals the amplifier to prevent theft and is convenient for installing equipment when space inside the room is limited. - Page 9 Front panel bass, treble, and input level controls — Bass, treble, and input level are easily adjusted from the front panel. Fanless design — The MPA 401-70V 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.
