Harman Kardon is currently showing off its latest flaghship home theater receiver, the 7.2-channel AVR 7550HD, at the CEDIA Expo. Like some of the other receivers in its range, it supports Dolby Volume technology that keeps its volume consistent no matter what source is playing, and is the very first to use Texas Instruments' Aureus DA710 dual audio digital signal processor for improved sound quality. Faroudja DCDi Cinema digital video processing uses a Torino chipset to upscale videos to near 1080p quality.
