About the MPA 152 Plus
The MPA 152 Plus is an ENERGY STAR qualified amplifier with an Extron exclusive, highly
efficient, advanced Class D amplifier design. It also features patented CDRS (Class D
Ripple Suppression) technology that provides a smooth, clean audio waveform and an
improvement in signal fidelity over conventional Class D amplifiers. The high efficiency
design generates very little heat and allows the amplifier to be fanless and operated in
environments with little or no ventilation.
This stereo integrated mini power amplifier delivers up to 15watts(rms) per channel stereo
or dual mono into a 4 ohm sound system, or 8watts(rms)per channel into an 8ohm
system. This model features a 90 dB signal‑to‑noise ratio with 0.1% THD+N, offering
exceptional performance for speaker systems requiring compact, economical, audio
amplification.
Front panel controls allow easy adjustment of bass and treble volume and input level.
The quarter rack size allows a variety of mounting options. The unit complies with UL 2043
for smoke and heat release for in‑the‑ceiling installations. It can be installed in the plenum
space of the ceiling. Alternatively, the units can be mounted on a tabletop, in a rack, under a
desk, or in a projector mounting kit.

Figure 1. Typical Application for the MPA 152 Plus
MPA 152 Plus Features
30 watts (rms) output power — Delivers up to 15watts(rms) per channel, stereo or
dual mono, into a 4 ohm speaker system or up to 8watts(rms) per channel into an 8ohm
system. Provides significant audio output for small integration projects with moderate sound
system needs.
Improved signal-to-noise ratio — The 90 dB unweighted signal‑to‑noise ratio allows
very low‑noise operation, ensures quiet, hiss‑free amplification, and maintains audio signal
integrity.
ENERGY STAR qualified amplifier — The MPA 152 Plus conserves energy and reduces
operating costs.
