PlenumAmp PMA-350HDALLAS, Texas /New York Netwire/ — Roemtech, LLC today announced release of its new PlenumAmp PMA-350H. Specifically designed for above ceiling applications, this plenum rated mixer/amplifier is equipped with Roemtech’s new Auto-HummBuster technology. In addition, it features three inputs, external volume control, P/A override, and green sleep mode. The PMA-350H is designed for conference room and classroom audio systems.

CEO and President, D. Thomas Emlinger states, “The PMA-350H is our most intelligent amplifier yet, delivering rich and clear audio, external volume control, and instant ground-loop elimination.”

The PMA-350H is a three input, 24 volt, 50 Watt, plenum rated stereo mixer/amplifier. To provide priority override for a Public Address system, the amplifier senses P/A audio and mutes connected audio sources to ensure delivery of important messages. In addition, this amplifier is compatible with the optional Roemtech external wall volume control which utilizes an industry standard 10K analog pot. The 6.48 inches wide x 1.65 inches high x 4.02 inches deep chassis dimensions provide for an easier installation in classrooms with limited space.

The PMA-350H includes Auto-HummBuster technology. This novel, patent-pending technology automatically suppresses noise that sometimes infiltrates classroom audio systems. Roemtech developed algorithms that listen to the audio on each input. After analyzing all audio inputs with and without filters, the internal microprocessor intelligently determines the optimal settings and then stores them.

The PlenumAmp PMA-350H is only available through authorized Roemtech audio-visual dealers. MSRP: $299.95, including a three-year warranty and a 60 Watt power supply.
