Features

Class D digital audio amplifier — For high efficiency and less heat production.
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 outputs are summed to produce a single left output.
Stereo/Dual Mono toggle switch — Allows the user to choose between stereo output or
to combine the left and right outputs and produce dual mono outputs.
Up to 15 watts (rms) per channel stereo output — Delivers up to
15 watts (rms) per channel, stereo or dual mono, into a 4 ohm speaker system or up to
8 watts (rms) per channel into an 8 ohm system.
Front panel controls — Input level, bass and treble are easily adjusted from the front panel.
Quick-plug speaker outputs — Speaker output is on a captive screw connector for quick
installation.
Volume and mute remote control — A rear panel, three-pin captive screw remote input
connector allows remote adjustment of volume and muting.
Always-on clip limiting — Reduces gain automatically to prevent amplifier clipping.
Compact size — The amplifiers are housed in a 1U high, 3 inch deep, quarter rack metal
enclosure, which offers flexible mounting options.
Suitable for use in Environmental Air Space — The MPA 152 is suitable for use in an
Environmental Air Space in accordance with Section 300.22 (c) of the National Electric Code.
