40W Plenum Rated Stereo/Mixer Amplifier

The Contemporary Research 232-AMP+ has amped up the audio power to 40 Watts. The unit is a compact, programmable mixer/amplifier aimed at integration with flat-panel displays and video projectors. The versatile amp features a stereo line-level display/projector audio input and two mono aux inputs, and outputs stereo sound at 40W RMS. The aux inputs mix levels with the stereo input, and can be set to mute or lower other inputs when active, ideal for wireless mics and paging applications. Complete RS-232 control allows for the ultimate flexibility and customization.

Compact yet Powerful

The 232-AMP+ is only 5.5" wide, 1.1" tall, 3.5" deep, and only weighs 8 oz. The amplifier packs 20W per channel at 4 Ohms. When combined with a CR tuner and pole mount, the 232-Amp+ serves as an integrated AV tuning/audio solution for video projector installations. The optional SMA bracket mounts the 232-Amp+ to the top of CR tuners, and a single RS-232 port can control a 232-series tuner and amp.
