Contemporary Research introduces new 232-Amp mixer/amplifier
At InfoComm 2008, Contemporary Research (CR) introduced the 232-Amp, 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 8W RMS per channel. The aux inputs mix levels with the stereo input and can be set to mute or lower other inputs when active.
As its name implies, the 232-Amp incorporates an RS-232 port to allow integration with custom control systems. The unit features programmable input levels plus maximum and minimum gain controls. The 232-Amp fastens to the top of CR’s 232- and iC-series tuners, mounts to displays or projectors or in an optional rack-mount. New iC-series tuners can link to the 232-Amp for interactive volume control, and one DC supply can power both units.
Full RS-232 control and status is available, allowing integration with custom control systems. In addition to setting master gain and input levels, the commands can also set max and minimum gain as well as aux input threshold and ducking levels. Installers can adjust performance manually in the field using onboard switches and level potentiometer. When combined with a Contemporary Research tuner and PoleCat pole mount, the 232-Amp serves as an integrated A/V tuning/audio solution for video projector installations.
