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.

DENON's higher-end models incorporate these low-noise designs,

such as the use of short rings.

•

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 power 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, 90 Watts Each

Front 90 W + 90 W (8 ohms, 20 Hz - 20 kHz, 0.08 % THD)

Center 90 W (8 ohms, 20 Hz - 20 kHz, 0.08 % THD)

Surround 90 W + 90 W (8 ohms, 20 Hz - 20 kHz, 0.08 % THD)

Surround Back 90 W (8 ohms, 20 Hz - 20 kHz, 0.08 % THD)

For optimum Dolby Digital and DTS reproduction, the AVR-1804 features high quality,

wideband audio amplification, providing 90 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.

■

Single-Channel Surround Back Power Amp for 6.1 Surround and

2 Speaker Terminals for 7.1 Surround

The AVR-1804 is equipped with a total of 6 power amps including one for the Surround

Back speaker to give you more clearly defined sound localization at the rear for 6.1-chan-

nel surround sources such as DTS-ES Discrete 6.1, DTS-ES Matrix6.1, Dolby Digital EX,

and DTS-ES NEO:6. The AVR-1804 also provides you with 2 speaker terminals for the

Surround Back channels, allowing for the ultimate home theater experience in amazing

7.1-channel Surround.

■

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-1804 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 SACD

The power amp circuits of the AVR-1804 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-1804 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-1804 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.

■

On Screen Display

The AVR-1804 lets you make system settings via diaplays on your TV scren from the

comfort of your chair.

■

Acclaimed Customization Feature

As with all of DENON’s high-grade A/V receiver, the AVR-1804 lets you adjust delay

times and other parameters so that you can customize the performance of the AVR-1804

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 Glow-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.
