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 (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 con-
ditions. 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.
