Packed with features to maximize audio and video fidelity, the AVR-689 is a powerful 7.1 channel receiver that incorporates the latest surround sound decoding technologies, along with sophisticated video signal handling and upconversion that allows both HDMI v1.3a video inputs as well as providing component video output.
The surround section features the same precision 32 bit floating point DSP technology found on our top-line models, and includes a full array of surround sound decoding functions, including Dolby Digital EX as well as DTS ES 6.1 discrete and matrix decoders for the most thrilling, theater-like surround sound experience. For improved acoustic accuracy, the AVR-689 features Audyssey MultEQ in-room acoustic measurement and correction that fine-tunes the listening space via the supplied microphone, with up to six measurement points to ensure even tonal balance. In addition, the AVR-689 is among the first to feature Audyssey’s remarkable Dynamic Volume processing, which eliminates irritating jumps in volume between TV shows and commercials, as well as Audyssey Dynamic EQ to ensure rich bass and smooth tonal balance, even at low volume levels. All seven amplifier channels feature equal power and lowest distortion, and the AVR-689 is equipped with dual zone multi-room capability that lets you run a 5.1 channel surround speaker system in the main room, while providing independent stereo audio to a pair of speakers in another room.
