The Extron MPA 401 is a quarter rack width, convection-cooled mono amplifier delivering 40 watts rms output power. This UL 2043, plenum rated design meets UL requirements for in-ceiling installations. The MPA 401 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. Three buffered inputs are available so three separate sources can be connected without altering performance. The Extron exclusive, high efficiency design generates very little heat and allows the amplifier to be convection cooled and operate in environments with little or no ventilation.

Energy Efficient Amplifier with Auto Power-Down

The MPA 401 ENERGY STAR qualified amplifier is an energy efficient product that conserves energy and reduces costs. With an auto power-down feature that automatically places the amplifier into standby after 25 minutes of inactivity, it consumes just 8 watts when idle and less than 1 watt in standby mode.

The MPA 401 is housed in a compact 1U, quarter rack width enclosure. This amplifier is UL 2043 plenum rated, allowing for a concealed installation above a drop ceiling to prevent theft while providing convenient placement of AV equipment.

The MPA 401 delivers 40 watts rms for high impedance speaker systems in voice reinforcement and distributed audio applications. The MPA 401 is available in 70 volt and 100 volt models.

The MPA 401 accepts balanced and unbalanced stereo or mono input signals. The front panel includes detented controls for bass, treble, and input level. The MPA 401 combines the left and right channels into a single mono output. An advanced, automatic clip limiter protects speakers from clipping distortion. For applications requiring volume adjustment and muting control from a location other than the amplifier, remote control capability is available using the optional Extron VCM 100 or VCM 200 analog volume and mute controller or VC 50 analog volume controller.
