AVR-4806CI
A/V Surround Receiver
THX Ultra2 Certified 7.1-channel A/V Surround Receiver
Denon’s AVR-4806CI 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-4806CI 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-4806CI is the first A/V receiver to offer Analog Video
to digital HDMI output conversion, which allows all video sources input through the AVR-4806CI 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-4806CI may be installed. Denon original technologies are present as well, DDSC-Digital, AL24 Processing Plus and the latest
Denon Link 3rd digital interface.
Moreover, AVR-4806CI is equipped with various network functions such as internet radio, audio streaming and A/V amplifier network
Setup.

■ 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-4806CI 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 XM Passport System*
*Subsciption to XM services also required.
Video Section
■ Video Up/Down Conversion capable of output to HDMI port
The AVR-4806CI 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.
■ 1080p upscaling
■ Component video switching
The AVR-4806CI is equipped with 3 sets of component video inputs. There are also
2 sets of component video outputs capable of simultaneous output, allowing compo-
nent 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-4806CI 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 system
The AVR-4806CI’s Ethernet and RS-232C ports provide support for serial control
using AMX, Crestron and others.
