has further developed its propriety AL24 Processing to support the 192 kHz
sampling frequency of DVD-Audio. AL24 Processing Plus thoroughly suppresses
quantization noise associated with D/A conversion of LPCM signals to reproduce
the low-level signals with optimum clarity that will bring out all the nuances
of the music. AL24 Processing Plus is applied to not only the front left and
right channels, but also the surround left and right, center and subwoofer
24-Bit, 192 kHz D/A
Converters: The AVR-3808CI uses highly accurate Burr Brown PCM-1791 Digital-to-Analog
converters, two for each channel, for a total of 16. The 192kHz sampling and
24-bit word length capabilities of the DACs allows you to play high-resolution
recordings and hear the increased clarity, detail and dynamic range of those
DDSC HD-Digital (Dynamic Discrete
Surround Circuit): The Denon AVR-3808CI is equipped with the latest technology in surround audio performance, DDSC
HD-Digital, featuring dual Analog Devices Hammerhead SHARC 32-bit floating point
DSP processors. All elements of the Surround Processor are optimized to the
highest standards by the use of selected high performance and discrete
components, particularly the A/D and D/A converters and the sophisticated DSP
Custom Integration: The AVR-3808CI carries
the "CI" stamp, which is Denon's certification to custom installers that the
receiver has advanced connectivity and control features often required for
custom home integration and theater applications using premium control systems.
These features include a RS232C jack for use with whole house control systems,
remote in/out IR command control, and assignable +12-volt triggers.
Up-Conversion Powered With DCDi By Faroudja: The AVR-3808CI is equipped with a
flexible video switching system that converts video signals in an effort to only
require one video connection from receiver to TV. The video switching system
features a Directional Correlation De-interlacing (DCDi) special video processor
developed by Faroudja that involves advanced algorithms to remove the jagged
edges that appear when standard interlaced video is viewed on progressive scan
displays. DCDi converts standard interlaced signals into progressive scan
signals in order to eliminate the stair-casing effect that conventional
up-converters can introduce to diagonal edges. Unlike most other conversion
circuits, this receiver will convert analog signals from composite video,
S-Video, and component video to HDMI up to 1080p.
- Composite Video: can be
converted to S-Video, component video, or HDMI
- S-Video: can be converted
to composite video, component video, or HDMI
- Component Video: can be
converted to composite video, S-Video, or HDMI (480i signals only when down
Note: Video signals
input as HDMI must be output via HDMI.
Noise Shaped Video (NSV): The
NSV precision video feature works in the digital domain to reduce noise in the
video signal frequency band in order to enhance video signal linearity, provide
accurate signal representations, and enhance the picture quality. Noise shaping
techniques can be combined with dynamic element matching techniques in order to
reduce the matching requirements of DAC elements by converting the analog
mismatch into and out of band noise. This approach of dynamic element
matching and noise shaping has been shown to allow the use of sigma delta
modulation at video data rates. NSV can achieve ultimate precision with 12-bit
fidelity in both digital-to-analog and analog-to-digital domains.
automatically detects and decodes the digital bitstream from a CD that has been
encoded through the special High Definition Compatible Digital (HDCD) process.

allows you to adjust the tone to achieve the desired sound
receiver has a personal memorize function that automatically memorizes the
surround modes and input modes selected for the different input sources. When
the input source is switched, the modes set for that source last time it was
used are automatically recalled. The surround parameters, tone control settings,
and playback level balance for the different output channels are memorized for
each surround mode.
The receiver is equipped with an Auto Setup and Room Equalization function, to
achieve the most ideal sound field for your room.
The AVR-3808ci's Audyssey MultiEQ XT
function is designed to optimize the sound quality at each listening position in
the room. The included DM-A405 microphone is used to measure test tones at each
listening position. This measured data is then analyzed using a program to
improve acoustic characteristics in the listening area. For best results at
least 8 positions should be measured, including a main position. The main
position is given more weight in the calculations. The Audyssey function adjusts
the following measurements automatically: Speaker Configuration, Distance,
Channel Level, Crossover Frequency, and Room EQ.
The Room EQ function offers the following adjustments:

function gives you the option of configuring the system differently if you
prefer. The amplifier features four different amplifier assignment
Bi-Amp: Four of the seven
amplifier channels can be used to bi-amp the front speakers, leaving three to
power other channels.
Dual Surround Speaker Mode:
The AVR-3808CI provides the ability to connect two different sets of surround
speakers, and place them in the appropriate locations in your home theater room,
so that you can enjoy both movie soundtracks and music listening, with optimum
results and no compromise. If you play one pair of surround speakers at a time
(Surround A or B), the minimum impedance of the connected speakers is 6 ohms. If
you play both pairs of speakers simultaneously (Surround A + B), the minimum
impedance of the connected speakers is 8 ohms.
Multi Zone/Multi Source Operation:
Denon's Multi-Zone/Multi-Source function lets you select different
audio/video sources for listening and viewing in different locations of your
home. The AVR-3808CI features a Main Zone (Zone 1), Audio/Video Zone (Zone 2)
and Audio Only Zone (Zone 3). The Main Zone 1
contains 7.1-channel playback of your audio/video gear in your main
entertainment room. The Audio/Video Zone 2 allows stereo audio and video
playback of another AV source connected to the receiver in another room of your
home via left/right RCA audio or speaker terminal output connections and a
composite video connector. Audio Only Zone 3 allows you to
play a stereo audio source connected to the receiver in a 3rd room of your house
via left/right RCA audio or speaker terminal output connections.
Note: Zone 2 and Zone 3
feature either a preamp-output or speaker terminal output so you can use
this amp or a separate amp to power speakers in another room. When using the
AVR-3808CI to power speakers in a second room of your home, the main zone is
restricted to 5.1-channel at the same time. Also, when using the AVR-3808CI
to power speakers in a second and third room of your home at the same time,
the main zone remains 5.1 channels, but the 2nd and 3rd Zone speakers are
mono. When using the receiver's
preamp output terminals for the second and third room you need an additional
amplifier in each room to power those speakers and the main Zone of the
receiver remains 7.1-channel.
