More about AV Tuners

Often times it can be useful to have a tuner in your AV installation. Not all displays can tune TV channels; video projectors and monitors do not have built-in TV tuners to receive off-air or cable TV signals. Tuners can also be used to monitor live camera feeds or over the air broadcasts. Presentation room switchers often need a dedicated tuner that can be routed to displays on demand. Contemporary Research has established a reputation for bringing superior tuner technology to the AV market.

About 232-ATSC HDTV Tuner

The 232-ATSC HDTV Tuner is an integrator-friendly universal HDTV tuner, controllable via two-way RS-232 and discrete IR commands.

Full Description & Specifications

The 232-ATSC HDTV Tuner is an integrator-friendly universal HDTV tuner, controllable via two-way RS-232 and discrete IR commands. Able to fit two-across in a 2RU rack space, the compact tuner outputs HDMI, RGB/Component, and composite video simultaneously. NTSC broadcasts are upscaled for HD display. Digital Dolby® 5.1/PCM audio is available from HDMI, coax, and optical connections, as well as variable-level stereo audio. Setup is a snap, employing on-screen menus, included IR remote, front-panel programming, and RS-232 control commands. For home theater applications, the 232-ATSC offers no-compromise full-bandwidth image quality of local HDTV broadcasts and can access multi-channel programs - features not supported by cable and satellite "HD" programming. For commercial installations, the 232-ATSC tunes in today's and tomorrow's programming, and can receive conventional cable channels as well as local HDTV broadcasts from an off-air antenna.
