■ 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-684 inherits these low-noise design from higher-end
models not to mention the use of short 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.
■ Fully Discrete, Equal Power Six Amplifier Channels, 75 Watts Each

(8 ohms, 20 Hz - 20 kHz, 0.08 % THD)
For optimum Dolby Digital and DTS reproduction, the AVR-684 features high quality, wideband
audio amplification, providing 75 watts power output for each of the six main channels. A
large capacity power supply includes a high current power transformer along with discrete
power output devices on all six amplifier channels for highest dynamic range and superb
reproduction clarity.
■ 32 bit High Quality DSP
A-high -quality 32-bit DSP “MELODY 32” from Analog Devices has been used in the DSP
processor, placing the AVR-684 at a higher rank than other models of this class in its ability to
accurately decode and reproduce the superior quality of surround sources.
■ 24 bit, 96 kHz High Resolution D/A Conversion
■ Wide-Range Play Capability for DVD-Audio and Super Audio CD
The power amp circuits of the AVR-684 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-684 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 Digital EX and DTS surround modes)
■ Personal Memory Plus, for Easy Operation
The AVR-684 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-684 lets you adjust delay times and
other parameters so that you can customize the performance of the AVR-684 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.
■ DTS-ES (Discrete 6.1 / Matrix 6.1) and DTS NEO:6 Decoder
■ Dolby Digital, Dolby Pro Logic II and Dolby Digital EX Decoder
■ 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.
■ Virtual Surround Mode
Surround yourself with sensational 3D soundfield envelopment using just one pair of speakers. The AVR-684's Virtual Surround mode
provides a dramatic psychoacoustic surround sound effect, using two speakers with all
sources.
■ 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
2. Virtual Surround
3. Rock Arena
4. Jazz Club
5. Video Game
6. Matrix
7. Mono Movie
■ Adjustable Cross-Over Switching
The AVR-684 supports subwoofer cross-over switching with a choice of 4 cross-over frequencies: 80, 100, 120 and 150. This lets you more accurately match the performance
characteristics of the subwoofer to the main speaker system.
