You'll never be at a loss for creative surround algorithms with the AVR-686S, irrespective of your listening source. The receiver's onboard surround processing includes Dolby Digital Surround EX, DTS, DTS 96/24 5.1 for DVD-Video, DTS ES Discrete 6.1, DTS ES Matrix 6.1, and Dolby Pro Logic IIx (for cinema, music, and games). Dolby Pro Logic IIx processing is the first technology to convert traditional stereo music and movie content into room-filling 5.1- or 6.1-channel sound. Listeners will also enjoy the seven DSP modes, which simulate the acoustic environments of a variety of live venues, such as a stadium, concert hall, or sports stadium.
The AVR-686S owes its superlative sound quality to its premium digital-audio technologies. This receiver is equipped with an Auto Setup function to achieve the most ideal sound field for your room. With the included microphone placed at your listening position, this powerful 32 bit floating point DSP automatically and accurately analyses, adjusts, and sets the speaker configurations for your system. The receiver also offers 24-bit, 96 kHz analog-to-digital conversion on all stereo analog inputs (except the multichannel analog jacks), along with 24-bit/192 kHz digital-to-analog conversion for all seven channels to ensure premium playback sound.
On top of the surround processing modes, the AVR-686S offers several features designed to improve your audio flexibility. Thanks to the multiroom capability, you can attach multiple speaker systems and enjoy music in rooms other than the main listening room. Listeners can then choose to play sound through one set of speakers only or all the speakers, depending on the situation. To make video connections simpler and more intuitive, the receiver also offers video up-conversion for composite and/or S-video sources. Video up-conversion translates all the signals to high-bandwidth component video with absolutely no compromise in video quality. In addition, the adjustable high- and low-pass crossovers (40, 60, 80, 100, 120, 150, 200, and 250) let you tailor the sound to suit your speakers and listening space.
Video connectivity stems from the three assignable sets of component video inputs, three S-video inputs, and four sets of composite inputs. Audio-wise, the receiver includes eight analog RCA stereo inputs and four digital inputs (one coaxial and three optical), along with a six-channel external analog input. The receiver measures 17.1 by 5.8 by 16.4 inches (W x H x D) and is backed by a two-year warranty.
