AVR-4806

A/V Surround Receiver

THX Ultra2 Certified 7.1-channel A/V Surround Receiver

Denon’s AVR-4806 has technology, the reference sound quality and an extensive feature set, that previously was only available on its

critically acclaimed sibling, the AVR-5805. But it also stands alone with the introduction of some exciting new technologies, not found

on any previously released Denon receivers. The AVR-4806 is the first product from Denon to offer XM Satellite Radio Ready ‘Connect

and Play’ capability. And for the ultimate in connection flexibility and ease of use, the AVR-4806 is the first A/V receiver to offer Analog

Video to digital HDMI output conversion, which allows all video sources input through the AVR-4806 to be output on one HDMI cable.

The highly regarded Audyssey MultEq setup system is included, to give more realism and higher sound reproduction to any environment

the AVR-4806 may be installed. Denon original technologies are present as well, DDSC-Digital, AL24 Processing Plus and the latest

Denon Link 3rd digital interface.

Audio Section

■ THX Ultra2 Certified 7-channel High Power Amplifier

Front 140 W + 140 W (8 ohms, 20Hz - 20kHz, 0.05 % THD)

Center 140 W (8 ohms, 20Hz - 20kHz, 0.05 % THD)

Surround 140 W + 140 W (8 ohms, 20Hz - 20kHz, 0.05 % THD)

Surround back 140 W + 140 W (8 ohms, 20Hz - 20kHz, 0.05 % THD)

The AVR-4806 proudly bears the THX Ultra2 logo, certifying that it satisfies the strict

standards of Lucasfilm, Inc., governing performance, features, sound quality, power,

stability into low-impedance speaker loads (3.2 ohms and higher), and ease of operation.

■ 'New DDSC-Digital,' for dramatically improved processing performance

The New DDSC (Dynamic Discrete Surround Circuit)- Digital is a high-quality

surround sound reproduction circuit designed by Denon, and forms the core of the

design concept that Denon pursues for all its A/V amps: to faithfully reproduce the

original intent of content producers. Denon has succeeded in developing a fully dis-

crete design for the New DDSC-Digital in which high-performance ICs are used in

independent blocks to form a signal processor that reproduces surround sound, and

the discrete design ensures that all channels are endowed with identical response

and quality of sound.

■ New 32-bit floating point DSP

Three of the latest 32-bit floating point DSPs for the decoder.

• 24-bit/192-kHz D/A Converter

The latest high-accuracy 24-bit/192-kHz D/A converter has been employed

for the audio DAC.

• High-performance A/D Converter

A high-performance A/D converter of 24-bit/192-kHz quality has been used

to significantly boost S/N and dynamic range.

■ 'AL24 Processing Plus,' for high sound quality

■ DENON Link, enabling high-speed, high-grade digital signal transmission

■ IEEE 1394 digital interface

■ Large-output Power Amp Section and Power Supply Configuration,

for stable high-power output

■ Stabilized, independent power supplies for each circuit

■ Chassis construction to suppress internal/external vibration

■ Pure Direct mode, for the pure enjoyment of music in high-quality sound

■ Configurable Center, Surround and Surround Back Amplifiers

• Multi-zone system: a 5.1-channel theater in the main room and a monaural

environment in a second and third rooms.

• "Bi-amp" system: Front (L/R) channels are bi-wired in a 5.1-channel theater to

improve playback quality in the front for enhanced listening enjoyment.

■ Pre-amp with Variable Gain Volume

■ New Auto Set-up and Room EQ, featuring MultEQ from

Audyssey, for overall listening area support using supplied

microphone

■ Full support for the most advanced surround playback formats

• Dolby Digital EX • Dolby Digital • Dolby Pro Logic IIx

• Dolby Headphone • DTS-ES • DTS 96/24 • DTS Neo:6 • DTS • HDCD

■ THX, THX Surround EX, THX Ultra2 Post Processing Modes

■ Original surround modes from Denon

■ XM Satellite Radio Ready with optional 'Connect and Play' antenna*

*Subsciption to XM services also required.

Video Section

■ Video Up/Down Conversion capable of output to HDMI port

The AVR-4806 includes a video up/down conversion function that allows the unit to

be connected to the video monitor via a single cable regardless of the video input

signal's format as follows:

1) Composite video signals are converted to HDMI (*1), component video, & S-video;

2) S-video signals are converted to HDMI (*1), component video, & composite video;

3) Component video signals are converted to HDMI (*1), composite video (*2), & S-video (*2).

*1. Output signal up-converted to HDMI retains the resolution of the input signal.

*2. Down-conversion from component video to composite or S-video applies only to 480i input signals.

■ Component video switching

The AVR-4806 is equipped with 3 sets of component video inputs. There are also 2

sets of component video outputs capable of simultaneous output, allowing component

video with high picture quality to be enjoyed on two monitors at the same time.

Settings do not need to be changed each time a monitor is switched. These component

video circuits achieve sharp HDTV video quality in a frequency range up to 100 MHz.

■ High-speed, high-accuracy 12-bit/216-MHz Video DAC

A high-speed, high-accuracy 12-bit/216-MHz video DAC is used in the video circuitry

for component video, S-video, and composite video signals. This DAC enhances the

reproducibility of delicate-level video signals, allowing high-definition video to be

played back with greater fidelity to the original images. In addition, noise shaped

video (NSV) technology improves video S/N for greater signal linearity.

■ Composite and S-video signal processing

The AVR-4806 uses a time base corrector (TBC) in converting composite video & S-video

signals to component video to suppress jitter in the video signal during playback.

Expandability

■ Analog EXT IN terminal

■ 3 Source and Zone Capability

■ Ethernet and RS-232C terminals, for external 3rd party control systems

and possible future upgrades
