TX-SR574 7.1-Channel Home Theater Receiver

The design philosophy behind the TX-SR574 makes good sense. Provide on-demand power for all channels; add powerful processing capabilities and dependable build quality; and stack it with versatility and options. The TX-SR574 takes today’s most sought after home entertainment components—like DVD recorders, cable/set-top boxes and gaming consoles—and conveniently switches between them with a single output to HDTV. It will also upconvert any other components connected by S-Video and composite connections. And when it comes to music and movie sources, the TX-SR574 accommodates the most contemporary formats available, even the yet-to-be-released surround formats for HD-DVD and Blu-ray Disc. And if you want to broaden your choices even further, the TX-SR574 provides access to XM® Satellite Radio and the iPod® with the appropriate set-up and peripherals. Such competitively priced completeness is bound to attract attention.
