Plenum Rated Amplifiers - Classroom Amplifiers

The ROEMTECH PlenumAmp PMA-240 comes with a compact, external, regulated 12V power supply at 4 amps. The plenum amplifier is rated at 20 watts per channel RMS for an impressive total output of 40 watts. This gives plenty of headroom for demanding applications with high ambient noise levels (such as school classrooms) while delivering clear, powerful sound.

Small enough to fit in the palm of your hand and weighing less than 1.1lbs, the PMA-240 is small enough to install just about anywhere. The unit comes with four screws holes to mount under a table or in a lectern or can easily be mounted in the plenum area using the MK-4N MagnaKlamp. The power is attached to the amplifier via captive screws and the amplifier is polarity tolerant - so it is impossible to connect the power in reverse. Because it can be installed in the plenum area, loss due to theft is a thing of the past, it is the perfect classroom amplifier.

The PMA-240 has two completely independent audio inputs each with dedicated gain control. Input one is line level stereo RCA and input two is line level stereo 3.5mm - so whether you are providing audio for a computer, wireless mic, video conferencing or a plasma screen - the PMA-240 is right for the job. And because it is the world's first plenum rated amplifier and mixer, it can easily be installed out of sight.

Here's the scenario: You wanted to put an amplifier in a room but couldn't find a good place for it. Perhaps a classroom or a conference room where the only good place for an amplifier is in the plenum area. But of course you couldn't put the amplifier in the plenum area because it wasn't plenum rated. That just changed. Introducing the ROEMTECH Plenum MixerAmp (PMA-240). Specifically designed from industrial grade components to withstand plenum temperatures while at the same time built to conform with stringent plenum standards, the plenum amp is finally here. Your installs just got easier.
