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.

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)

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
