The Extron MPA 601 is an ENERGY STAR® qualified mono audio amplifier delivering 60 watts rms output. Housed in a compact convection cooled and UL 2043 plenum enclosure, it meets UL requirements for in-ceiling installations. The MPA 601 employs a highly efficient advanced Class D amplifier design featuring our patented CDRS™ - Class D Ripple Suppression technology providing a smooth, clean audio waveform and an improvement in signal fidelity over conventional Class D amplifiers. Three stereo inputs are summed together so three separate sources can be connected simultaneously. With more power in a compact design, a defeatable standby timer and professional performance, the MPA 601 is ideal for applications with space restrictions that require sufficient power for a small to medium distributed audio system.

Energy Efficient Amplifier with Auto Power-Down

The MPA 601 ENERGY STAR qualified amplifier is an energy efficient product that conserves power and reduces costs. The convection-cooled, fanless design ensures quiet and reliable operation and reduced heat loads in the rack. 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.

Defeatable Standby Timer

For sensitive applications that require uninterrupted operation, the standby timer can be disabled.

Compact, Plenum-rated Enclosure

The MPA 601 is housed in a compact 1U, quarter rack width enclosure. It can be mounted in a small rack, within a credenza, within a lectern, or behind a display in lobby or commons locations. With a UL rating for use in plenum air spaces, it also allows for concealed installation above a drop ceiling to prevent theft while providing convenient placement of AV equipment.

Professional Grade Performance

The MPA 601 delivers 60 watts rms for high impedance speaker systems in voice reinforcement and distributed audio applications. The MPA 601 is available in 70 volt and 100 volt models. With professional grade signal-to-noise of greater than 90 dB and ultra-low noise of less than 0.1% THD+N makes the MPA 601 ideal for use in applications where fidelity is critical.

The amplifier can be used by itself to feed a single speaker tapped at 60 watts, in a speaker zone comprised of 60 speakers tapped at 1 watt each, or in any combination in between. In larger paging and background music systems, the MPA 601 can be used to power smaller speaker zones, leaving larger amplifiers, such as the Extron XPA 4002‑70V, to power the larger zones.

The MPA 601 accepts balanced and unbalanced stereo or mono input signals. The front panel includes detented controls for bass, treble, and input level. The MPA 601 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 VC 50, VCM 100 or 200, or the MLC Plus 84, 100, or 200 MediaLink Plus controllers.
