June 28, 2000

Presenting The Most Advanced

Home Theatre Receiver Ever

Created: The New Denon


Ultimate-Performance A/V Receiver Is

First-Ever To Include THX® Surround


DTS®-ES Discrete 6.1, DTS-ES Matrix 6.1

And DTS Neo:6 Surround Sound

Denon Electronics announced the introduction of its new flagship AVR-5800 A/V

surround receiver, the world’s first audio component to offer DTS-ES Discrete

6.1, DTS-ES Matrix 6.1 and DTS Neo:6 surround sound decoding. In addition,

the THX® Ultra-certified AVR-5800 incorporates a host of leading-edge digital

audio and video technologies such as THX Surround EXâ„¢ decoding,

24-bit/192kHz D/A conversion and a seven-channel amplifier section, for

performance and operational flexibility far beyond the capabilities of any

previously available home theatre receiver.

David Birch-Jones, Denon Marketing Manager, noted, "With the introduction of

the new AVR-5800, Denon has elevated the performance standard for

state-of-the-art audio/video receivers yet again. Without question, the AVR-5800

is the finest A/V receiver ever created, and includes a number of technological

breakthroughs that significantly expand the capabilities of high-end A/V receiver


DTS Extended Surround: The Next Generation Of Surround Sound Decoding

The Denon AVR-5800 is the world’s first audio/video component to be equipped

with a DTS-ES Discrete 6.1-channel decoder, developed by DTS to provide

dramatically improved 360-degree soundfield reproduction and exceptionally

realistic surround sound localization. The new DTS-ES Discrete decoding system

adds a discrete surround back channel to the traditional 5.1-channel loudspeaker

configuration, enabling more faithful reproduction of the multi-channel sound mix

originally designed by the film or music producer at the dubbing stage. When a

6.1-channel DTS-ES Discrete source is played, the AVR-5800 automatically

detects the signal and plays in 6.1 discrete mode.

The AVR-5800 also supports DTS-ES Matrix and DTS Neo:6 matrix 6.1-channel

processing. DTS-ES Matrix decoding produces the effect of 6.1-channel sound

by extracting a surround back channel from the left and right surround channels,

and is compatible with the growing number of movies released on DVD with

DTS-ES encoding. The DTS Neo:6 matrix surround function provides up to 6.1

channels of surround sound audio from stereo program material, and can be used

with virtually any two-channel digital or analog stereo audio source.

In addition to the new DTS formats, the Denon AVR-5800 includes THX

Surround EX processing, which provides an additional surround back channel

when decoding Dolby® Digital Surround EX-encoded sources, to create a

6.1-channel soundfield. The AVR-5800 also provides unexcelled Dolby Digital

and DTS 5.1-channel surround sound decoding, THX 5.1 and 4.0

post-processing and a variety of useful DSP modes. For heightened surround

sound music listening enjoyment from stereo program material, the AVR-5800

includes Denon’s exclusive 5-Channel Stereo mode, in which both sets of left

and right speakers (front and rear) reproduce full fidelity unprocessed stereo and

the center channel provides an L + R blend.

The AVR-5800 is designed to bring out the best in all existing surround sound

formats and program material, thanks to its Dual Surround Mode Speaker

Switching featuring two pairs of left and right surround channel speaker outputs.

This unique Denon feature allows the user to install two sets of surround

speakers - diffuse surround and direct radiating - and choose the best set of

surround speakers for either movie or music listening without compromising

either listening mode. For example, the listener can choose between

side-mounted dipole/bipole speakers when listening to Dolby Digital or DTS

movie soundtracks, and direct radiating speakers mounted at the rear corners

when listening to 5.1-channel music surround program material.

The Denon AVR-5800 incorporates the most advanced digital technologies

available to achieve an extraordinary level of sonic accuracy. The AVR-5800

utilizes dual Analog Devices SHARC 32-bit floating point DSP processors - the

most advanced DSP devices on the market. Each of these state-of-the-art chips

boasts a processing speed of 50MIPS (millions of instructions per second), with a

computational power of 80MFLOPS (millions of floating point operations per

second) sustained, 120MFLOPS peak. The AVR-5800 also utilizes the

latest-generation Analog Devices AD-1853 24-bit/192kHz D/A converters,

featuring two DAC channels per each audio channel in a differential configuration

for widest dynamic range and lowest noise floor. In the highest quality Pure Direct

stereo mode, the AVR-5800 automatically re-configures the DACs to provide

eight-DAC dual differential operation - four DACs per each audio channel.

This leading edge DSP circuitry operates in conjunction with Denon’s proprietary

DDSC-D (Dynamic Discrete Surround Decoder-Digital) and 24-bit ALPHA

technologies to further enhance sonic performance. The DDSC-D circuit

dynamically allocates processing power for optimum surround sound decoding

performance, while the 24-bit ALPHA processing circuit uses sophisticated

interpolation algorithms and digital filtering to improve low-level resolution. The

sonic result is significantly improved fidelity and dynamic range and a much more

musically natural sonic presentation.

An additional DDSC-D design feature is the use of a separate, parallel stereo

analog pathway for highest quality stereo audio reproduction. Unlike competitive

A/V receivers, which digitize incoming analog signals even in stereo mode, the

AVR-5800 has a dedicated analog stereo pathway that keeps the main stereo

signal information in the analog domain (above 80Hz). This preserves the high

quality analog output from LP, or a CD player or CD changer with HDCD decoding,

with no A/D and D/A digital artifacts or added noise. The analog pathway also

includes a parallel bass management level memory function that duplicates the

speaker and subwoofer level settings of the digital sources and keeps speaker

and subwoofer levels consistent when switching between analog and digital


More Features And Flexibility Than Ever Before

Along with unmatched surround sound performance, the Denon AVR-5800

offers unmatched operational flexibility. Its power section includes seven

all-discrete channels of amplification, to drive the all the main channels in a 7.1

multi-channel system without the need for external amplification. Each channel -

left, center and right front, left and right rear surround, and the left and right

surround back channels - delivers a remarkable 170 watts of high-current power,

the highest power output ever from a Denon A/V receiver (into 8 ohms, from

20Hz-20kHz, with no more than .05% THD). If desired, the amplifier channels can

be reassigned to accommodate system configurations using less than seven

main channels, while utilizing the receiver’s full amplification capability.

The AVR-5800 provides the most extensive complement of features and control

options of any A/V receiver ever created. Among the highlights are three sets of

component video inputs, nine assignable optical and coaxial digital inputs plus an

additional digital input for Dolby AC-3â„¢ RF laser disc, automatic digital/analog

input source selection, and a Pure Direct Mode that reconfigures the receiver’s

D/A converter section to eight-DAC dual-differential operation and shuts off all

unnecessary circuitry (including the video section) for highest-quality

reproduction of two-channel digital and analog music sources.

Other unique features include three-source/three zone multi-room audio and

video capability, an Enhanced Bass Management system that allows the user to

optimize bass response for any home theatre speaker configuration, Denon’s

Personal Memory Plus function that retains surround sound settings for each

program source in memory and much more. The AVR-5800 also includes a full

array of "standard" A/V receiver features, inputs and outputs.

Although the Denon AVR-5800 incorporates every conceivable feature to

accommodate today’s most advanced audio and video program sources and

home entertainment systems, it is also designed to accommodate future formats

and upgrades. For example, the AVR-5800 includes an RS-232C control port for

connection to external whole-house control systems, with a software/firmware

upgrade pathway, and features IEEE 1394 "FireWire" upgrade capability via an

upgradeable DSP board and digital jack panel.

The AVR-5800 is supplied with Denon’s new AKTIS RC-8000 Programmable

LCD Remote Control and companion RC-8001ST Charger Base/RF Relay

Station. The new AKTIS provides complete control of even the most

sophisticated home entertainment systems from a single programmable and

customizable device, and transmits both IR and RF control signals for total system

control flexibility including multi-room operation.

Along with ultimate performance, the Denon AVR-5800 is built to ultimate quality

standards. Its chassis construction is designed to optimize audio performance

through the use of isolated digital and analog circuits, extensive internal

shielding, premium-quality components throughout and other refinements.

The AVR-5800 will begin shipping August 2000 at a suggested retail price of
