Denon AVR-685S
Manufacturer's Description
High-Quality Surround Sound Reproduction
NEW High Resolution 32bit Floating Point DSP
24 bit, 192 kHz High Resolution D/A Conversion Capability
High-grade Up Conversion
This video transcoding (up-conversion) allows you to enjoy high picture quality from all video sources connected to the AVR-685. Since composite and S-video signals are up-converted into component video signals and output to the monitor, all you need to do is connect a monitor that has component video input jacks.
3 Sets of Component Video Inputs
The AVR-685 is equipped with 3 sets of component video inputs and 1set of monitor outputs (all RCA terminals)
Fully Discrete, Equal Power 6 Amplifier Channels, 110 Watts Each
Front 110 W + 110 W (6 ohms, 1 kHz, 0.7 % THD)
Center 110 W (6 ohms, 1 kHz, 0.7 % THD)
Surround 110 W + 110 W (6 ohms, 1 kHz, 0.7 % THD)
Surround Back 110 W (6 ohms, 1 kHz, 0.7 % THD)
For optimum Dolby Digital and DTS reproduction, the AVR-685 features high quality, wideband audio amplification, providing 110 watts power output for each of the 6 main channels. A large capacity power supply includes a high current power transformer along with discrete power output devices on all 6 amplifier channels for highest dynamic range and superb reproduction clarity.
DENON's Basic Design for High-Quality Sound Reproduction
Power Transformer for High Power Driven
The chassis that supports the large transformer has been designed to absorb vibration, and the transformer is housed inside a highly rigid frame to secure it more solidly to the chassis. In addition, a cushioning material has been placed around the core of the transformer to minimize interference on the signal and enable more faithful reproduction of the original sound. The AVR-685 inherits these low-noise design from higher-end models not to mention the use of sort ring.
Twin Drive Rectifier
DENON's Twin Drive Rectifier design uses two rectifying diodes in parallel to bring out the maximum potential of the large transformer. Since the rectifiers recharge the large block capacitors at low impedance, they are able to supply ample current to reproduce deep basses as well as sudden bursts of sound from percussion or other musical instruments.
Large Aluminum Extruded Heatsink
DENON uses large heatsink made of extruded aluminum. They have been placed in a design that ensures mostly uniform temperatures throughout the heatsink so that the output transistors for all channels can be driven under uniform conditions. This in turn ensures that all channels respond with equal performance to the demands of the audio signals.
Wide-Range Play Capability for DVD-Audio and Super Audio CD
The power amp circuits of the AVR-685 have been meticulously designed to reproduce the exceptionally high sound quality with wide frequency response from 10 Hz to 100 kHz.
Cinema Equalizer
The sound from movie sources recorded in Dolby Digital, DTS or other formats emphasizes high-frequency range due to a theater`s front speakers being placed behind the movie screen. If this sound is reproduced in the home theater without correction, the high-frequency range is too strong. The AVR-685 features a Cinema Equalizer to correct these high-frequency components so that the sound is clearer and easier to listen to. (For Dolby Digital, Dolby Pro Logic II, Dolby Pro Logic IIx, Dolby Digital EX and DTS surround modes)
Personal Memory Plus, for Easy Operation
The AVR-685 includes the Personal Memory Plus function that automatically remembers the surround mode you last used for each program source, so that you do not need to select the mode again for that program.
Acclaimed Customization Feature
As with all of DENON`s high-grade A/V receiver, the AVR-685 lets you adjust delay times and other parameters so that you can customize the performance of the AVR-685 to suit your own home theater and enhance operating ease. The adjustments are 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 surround mode, in Personal Memory Plus so constant readjustments are not required.
Multi-Function Preset Memory Remote Controller with Glo-keys
The supplied system remote controller features a large selection of remote control codes to operate other components in your home theater system, including codes for selected DENON models, along with remote control codes from other manufacturers. The most frequently used buttons are laid out separately for TV, VCR and DVD, for maximum ease-of-use.
*Remote control codes cannot be used with the products of other manufacturers and some DENON products.
