TX-SR804 THX Select2 7.1-Channel Home Theater Receiver
 

Driving Home Theater with Pinpoint Accuracy, Potent Power and Multi-Entertainment Options

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-SR804 7.1-channel A/V surround home theater receiver. You have video switching and upconversion through HDMI (version 1.1) and component video enabling an effortless, high-bandwidth transfer of video and audio signals to the latest HDTV displays. Also, the inclusion of a Time Base Corrector (TBC) will effectively prevent any picture deterioration caused by timing inaccuracies. With numerous other features that help the TX-SR804 to stamp its class—Wide Range Amplifier Technology (WRAT); Vector Liner Shaping Circuitry (VLSC); multizone playback with a 12 V trigger; a wide-ranging crossover adjustment; RS232 & IR connectivity; as well as XM® radio and iPod® integration capabilities—this receiver stands out for its seemless, powerful functionality.
