Harman Kardon and Dolby Volume Make Joint Debut

The Harman Kardon AVR 7550HD ($2799) is the one of first surround receivers to feature Dolby Volume, one of the most sophisticated signal manipulation circuits to come along in years. It can take the edge off offensively toppy TV ads and intelligently reduce the dynamics of movie soundtracks, for late-night viewing, without losing intelligibility. Other attractions include 110 watts times seven, internet radio, and of course the full panoply of next-gen surround codecs via HDMI 1.3a.
