Versatility at its best! The AVR 645 not only switches two HDMI; 1.1 sources, it is able to decode Dolby Digital, DTS and PCM audio streams from the HDMI inputs. Add USB audio, iPod connectivity and XM-Ready capability to our EzSet/EQ system and high-current amplifier, and the AVR 645 performs with ease. Equally impressive on the video side is transcoding so that all analog video inputs may be viewed via component outputs, and A/V Sync Delay, which reconnects the timing of sound and images. There is no better combination of sound and image anywhere.
