Denon's AVR-689 is packed with features to maximize audio and video fidelity. 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 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.
Improved Acoustic Accuracy
Comes with 3 HDMI (ver1.3a) inputs and 1 HDMI (ver1.3a) output
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.
State of the Art Solutions for Superior Quality
This AV receiver includes a robust power source for each block for a stable supply of current. This produces a clear power circuit that prevents unwanted noise from affecting the sound. The dedicated CPU transformer is separate from the audio and video circuitry. It is also endowed with a powerful rectifier circuit with block capacitors and a bridge diode to supple a stable current with negligible noise.
The simple and straight design concept of the minimum signal path has been implemented in the signal paths to contribute to immaculately clean audio and video playback. Signal paths are as short as possible to keep the signal degradation in the audio and video circuitry to an absolute minimum.
Finally, the vibration resistant direct mechanical ground suppresses the adverse influences of vibration sound quality. The power transformers, a source of vibration, have been securely mounted to the highly rigid bottom chasses. Direct mounting of the cast-iron feet to the radiator in near proximity to each other also servers to suppress mutual vibrations with the power transformers and other sources of vibration.
With Denon, you get cutting edge technology and smart solutions to ensure top of the line audio and video quality. |
