Company officials said the Energy Star-qualified amplifier features an exclusive, highly efficient, advanced Class D amplifier design with patented Class D Ripple Suppression (CDRS) technology that provides a smooth, clean audio waveform and an improvement in signal fidelity over conventional Class D designs. CDRS allows the amplifier to be fanless and operate in environments with little or no ventilation, according to the company.

"The MPA 401, along with the XTRA Series, are the industry's first Energy Star-qualified commercial amplifiers that use less energy, run cooler, and take up less space than competitive models," said Casey Hall, Extron vice president of sales and marketing for North America, in a statement.

With an auto power-down feature that automatically places the amplifier into standby after 25 minutes of inactivity, the MPA 401 consumes just 8 watts when idle and less than 1 watt in standby mode, according to Extron. It accepts balanced and unbalanced stereo or mono inputs.

The front panel includes 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. The MPA 401 features remote control capability for volume adjustment and muting.
