MPA 401-70V and MPA 401-100V Description
The Extron MPA 401-70V and MPA 401-100V integrated mini power amplifiers provide
mono amplification for speaker systems that require compact and economical audio
solutions. Both amplifiers accept balanced or unbalanced, stereo or mono inputs and
provide a summed mono output. The MPA 401-70V delivers up to 40 watts (rms) for a
high-impedance, 70 V distributed sound system. The MPA 401-100V delivers up to 40
watts (rms) for a high-impedance, 100 V distributed sound system.
Front panel controls allow easy adjustment of bass, treble, and input levels. Volume can
be controlled remotely by the Extron VCM 100, VC 50, or MLA VC 10.
Both amplifiers feature high efficiency, Class D amplifier design with advanced CDRS
(Class D Ripple Suppression) technology that eliminates EMI emissions and interference
with sensitive AV equipment. The design allows the amplifiers to be fanless and operate in
environments with little or no ventilation. Both amplifiers meet UL 2043 for smoke and fire
code for above-the-ceiling installations.
