Extron’s new MPA 152 Plus is a new quarter-rack-width, stereo-integrated mini power amplifier that delivers 15 watts rms per channel and provides several performance enhancements over the previous MPA 152. The MPA 152 Plus features a 90 dB signal-to-noise ratio with 0.1 percent THD+N. The MPA 152 Plus is an ENERGY STAR qualified amplifier with an efficient Class D amplifier design. It also features CDRS – Class D Ripple Suppression technology that provides a smooth, clean audio waveform and an improvement in signal fidelity over conventional Class D amplifiers. Extron says this exclusive high efficiency design generates very little heat and allows the amplifier to be fanless and operate in environments with little or no ventilation.
The MPA 152 Plus ENERGY STAR qualified amplifier is an energy efficient product that conserves energy and reduces costs. It includes a defeatable auto power-down feature that automatically places the amplifier into standby after a period of inactivity, and consumes 4 watts when idle and less than 1 watt in standby mode. The MPA 152 Plus is housed in a compact 1U, quarter rack width enclosure and is UL 2043 plenum rated, which allows for a concealed installation above a drop ceiling to prevent theft while providing convenient placement of AV equipment. It delivers 15 watts rms per channel into 4 ohms and 8 watts rms into 8 ohms. The MPA 152 Plus is optimized for driving four 8 ohm speakers, two in parallel per channel.
