The What: Extron Electronics’ MPA 152 Plus is now available. The 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 What Else: The MPA 152 Plus features a 90 dB signal-to-noise ratio with 0.1% THD+N, offering performance for speaker systems requiring compact and economical audio amplification. The MPA 152 Plus is an ENERGY STAR qualified amplifier with an advanced Class D amplifier design. It also features patented CDRS - Class D Ripple Suppression technology designed to provide a smooth, clean audio waveform and an improvement in signal fidelity over conventional Class D amplifiers. The 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 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.

Why This Matters: "The MPA 152 Plus offers several refinements in performance over the MPA 152, continuing the progression of improvements to our mini power amplifier series," said Casey Hall, Vice President of Sales and Marketing for Extron. "Rather than rely on the unknown quality of the amplifier and speakers built into displays, the MPA 152 Plus used with Extron speakers provides a significant step-up for classrooms and other spaces."
