Denon DTS-ES AVR-685 User Manual

NEW MODEL INFORMATION

DTS-ES and Dolby Digital EX A/V Receiver

AVR-685

DTS-ES Discrete 6.1 and Dolby Digital EX with Power Amps for 6 Channels

■

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
Center 110 W
Surround 110 W + 110 W
Surround Back 110 W
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.

(6 ohms, 1 kHz, 0.7 % THD)
(6 ohms, 1 kHz, 0.7 % THD)
(6 ohms, 1 kHz, 0.7 % THD)

• 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.

AVR-685

■ 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.

■

6 Channel Stereo Mode

DENON's popular 6 Channel Stereo mode transforms your favorite 2-channel sources
such as CD, tape, stereo radio and stereo video sources into exciting surround
sound, free of delay effects and unnatural artifacts, from all six speakers. This 6
Channel Stereo mode was originally developed by DENON to enhance music lovers'
enjoyment of home theater ambience.

DENON DSP Surround Modes Add Listening Excitement

Put yourself in the middle of your favorite concert hall and music environments
with DENON's DSP acoustic environment simulation modes. These DSP modes
add spacious surround sound enhancements to your favorite music and video
sources, and include these distinctly different sounding effects:

1. 5 / 6 Channel Stereo 5. Video Game

2. Virtual Surround 6. Matrix

3. Rock Arena 7. Mono Movie

4. Jazz Club

■

Adjustable Cross-Over Switching

The AVR-685 supports subwoofer cross-over switching with a choice of 8 cross-over
frequencies: 40/60/80/100/120/150/200/250Hz. This lets you more accurately match
the performance characteristics of the subwoofer to the main speaker system.
