TX-SR803 THX Select2 7.1-Channel Home Theater Receiver
 

To create an A/V home theater receiver of exceptional quality, the challenge lies in incorporating the delicate processing circuits and amplifier components into the same chassis. When they both draw on the same power source, the amplifier dominates at peak moments. In a good design, it all works smoothly—as with the THX Select2 Certified TX-SR803 7.1-channel A/V surround home theater receiver. You have a wealth of connectivity options, including HDMI (version 1.1) and component video for an effortless, high-bandwidth transfer of video and audio signals to the latest HDTV displays. Also, the inclusion of a TBC (Time Base Corrector) will effectively prevent any picture deterioration caused by timing inaccuracies. With a flood of other features that help the TX-SR803 to stamp its class—Auto Speaker Set-up with Microphone, multizone playback, VLSC (Vector Liner Shaping Circuitry) and 192 kHz/24-bit DACs on all channels, XM Satellite Radio and iPod playback capabilities—you’re looking at a powerful blend of superb design and functionality
