AVR-686A/V ReceiverDTS-ES Discrete 6.1 and Dolby Digital EX with Power Amps for 7 Channels High-Quality Surround Sound Reproduction• High Resolution 32bit Floating Point DSP• 96 kHz Processing Circuit• 3 Sets of Component Video Inputs• 3 Sets of S-Video Switching Auto Setup with MicrophoneThe AVR-686 is equipped with an Auto Setup function, toachieve the most ideal sound field for your room. With themicrophone placed at your listening position, the powerful32bit floating point DSP automatically and accuratelyanalyses, adjusts and sets the speaker configurations ofyour system. Fully Discrete, Equal Power 7 Amplifier Channels, 75 Watts EachFront 75 W + 75 W (8 ohms, 20 Hz - 20 kHz, 0.08 % THD)Center 75 W (8 ohms, 20 Hz - 20 kHz, 0.08 % THD)Surround 75 W + 75 W (8 ohms, 20 Hz - 20 kHz, 0.08 % THD)Surround Back 75 W + 75 W (8 ohms, 20 Hz - 20 kHz, 0.08 % THD)For optimum Dolby Digital and DTS reproduction, the AVR-686 features high quality, wide-band audio amplification, providing 75 watts power output for each of the 7 mainchannels. A large capacity power supply includes a high current power transformeralong with discrete power output devices on all 7 amplifier channels for highest dynam-ic range and superb reproduction clarity. DENON's Basic Design for High-Quality Sound Reproduction• Power Transformer for High Power DrivenThe chassis that supports the large transformer hasbeen designed to absorb vibration, and the transformer is housed inside a highly rigidframe to secure it more solidly to the chassis. In addition, a cushioning material hasbeen placed around the core of the transformer to minimize interference on the signaland enable more faithful reproduction of the original sound. The AVR-686 inherits theselow-noise design from higher-end models not to mention the use of short ring.• Twin Drive RectifierDENON's Twin Drive Rectifier design uses two rectifyingdiodes in parallel to bring out the maximum potential of thelarge transformer. Since the rectifiers recharge the largeblock capacitors at low impedance, they are able tosupply ample current to reproduce deep basses as well assudden bursts of sound from percussion or other musicalinstruments.• Large Aluminum Extruded HeatsinkDENON uses large heatsink made of extruded aluminum.They have been placed in a design that ensures mostlyuniform temperatures throughout the heatsink so that theoutput transistors for all channels can be driven under uni-form conditions. This in turn ensures that all channelsrespond with equal performance to the demands of theaudio signals. Wide-Range Play Capability for DVD-Audio and Super Audio CDThe power amp circuits of the AVR-686 have been meticulously designed to reproducethe exceptionally high sound quality with wide frequency response from 10 Hz to 100 kHz. Dual Channel Surround Back Power Amp for 7.1 SurroundThe AVR-686 is equipped with a total of 7 power amps including 2 for the SurroundBack channel speaker to give you more clearly defined sound localization at the rearfor 6.1-channel surround sources such as DTS-ES Discrete 6.1, DTS-ES Matrix 6.1,Dolby Digital EX, and DTS-ES NEO:6. Assignable surround back (L/R) amplifiers for front (L/R) channel bi-amping,or for Multi-zone playbackAmplifiers initially reserved for Surround back (L/R) channels can be assigned to bi-wire Front (L/R) channels to improve playback quality in the front for enhanced listen-ing enjoyment. Or the amplifiers can be assigned to Zone 2 speakers (with multi-source), in addition to PREOUT for Zone 2. Cinema EqualizerThe sound from movie sources recorded in Dolby Digital, DTS or other formats empha-sizes high-frequency range due to a theater’s front speakers being placed behind themovie screen. If this sound is reproduced in the home theater without correction, thehigh-frequency range is too strong. The AVR-686 features a Cinema Equalizer tocorrect these high-frequency components so that the sound is clearer and easier tolisten to. (For Dolby Digital, Dolby Pro Logic II, Dolby Digital EX and DTS surround modes) Personal Memory Plus, for Easy OperationThe AVR-686 includes the Personal Memory Plus function that automatically remem-bers the surround mode you last used for each program source, so that you do notneed to select the mode again for that program. Acclaimed Customization FeatureAs with all of DENON’s high-grade A/V receiver, the AVR-686 lets you adjust delaytimes and other parameters so that you can customize the performance of the AVR-686 to suit your own home theater and enhance operating ease. The adjustmentsare easy to make via a dialog format on the fluorescent display on the front panel.These customized features are then stored, for each source input and surroundmode, in Personal Memory Plus so constant readjustments are not required.TENTATIVE
