About the MPA 152
The MPA 152 is an ENERGY STAR ® qualified, high performance, compact, power amplifier.
It delivers up to 15 watts (rms) per channel stereo or dual mono into a 4 ohm sound system,
or 8 watts (rms) per channel into an 8 ohm system.
Front panel controls allow easy adjustment of bass and treble volume and input level.
The unit meets UL smoke and fire code for in-the-ceiling installations and can be stored in
the plenum space of the roof.
Alternatively, the units can be mounted on a tabletop, in a rack, under a desk, or in a
projector mounting kit.

MPA 152 Features
ENERGY STAR® qualified amplifier — The MPA 152 is available as an ENERGY STAR
qualified amplifier, with an auto power-down feature that automatically places the amplifier
into standby after 25 minutes of inactivity, dramatically reducing power consumption.
Extron Patented CDRS™ - 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 AV equipment such as wireless microphones.
Ripple Steering technology — Produces cleaner, low-emission, audio output signals.
Fixed switching frequency — Switches at a frequency below the AM band, which
reduces the chance of radio interference.
Three audio inputs — Accepts one balanced or unbalanced input pair (captive screw),
one unbalanced pair (RCA), and one unbalanced pair (TRS), providing up to three right and
three left channel inputs. All three right inputs are summed to produce a single right output;
all three left inputs are summed to produce a single left output.
