Harman Kardon A/V receivers are renowned for their power, performance and ease of use, and the AVR 7550HD will only enhance that reputation. Among the fi rst receivers to offer Dolby Volume technology, which automatically adjusts volume levels when switching between sources and channels, the AVR 7550HD delivers 110 watts of power to each of the seven channels, plus two subwoofer outputs. It accepts a universe of inputs, including HDMI, component, S-video, USB and broadband Internet, as well as The Bridge II docking station (included) for iPod A/V playback, control and charging. Every Dolby and DTS technology is here, as is Faroudja DCDi Cinema and our exclusive Logic 7 processing. Zone II remote, Zone II OSD and A-BUS technologies work together to greatly simplify multiroom A/V applications.
