4FEATURES
1. DENON Proprietary Digital Technology
1) NEW D.D.S.C.-Digital (Dynamic Discrete Surround Circuit)
Powered by four high performance, high speed 32 bit floating
point DSP processors, the AVR-5805 represents the pinnacle
of precision DSP processing technology. Unlike competitive
units, DENON’s discrete surround technology consists of
selected individual processors and ancillary elements, working
in harmony via proprietary DENON inter-IC digital communication
technology.
2) DENON Link
With select DENON DVD players that feature DENON Link
digital outputs, encrypted digital multi-channel audio transfers
to the AVR-5805 directly, eliminating unnecessary digital-to-
analog and subsequent analog-to-digital conversions for the
highest possible signal transfer integrity. The DENON Link
function supports up to ultra high resolution 192 kHz DVD-A
digital datastreams, for maximum reproduced fidelity.
3) Latest AL24 DSP Processing
DENON’s acclaimed Advanced AL24 DSP processing improves
the fidelity of high resolution stereo PCM sources such as CD
and DVD (up to 192 kHz sampling frequencies), by
sophisticated DSP processing algorithms that improve low
level detail and enhance fidelity by upsampling and adaptive
filtering techniques. Advanced AL24 provides increased
dynamic range and spatial information; bring out all the
nuances with optimum clarity and natural fidelity.
4) AL24 DSP Processing For All Channels
For the AVR-5805, DENON’s AL24 processing supports multi-
channel DVD-Audio for all channels, including the Zone2 multi-
channel theater channels, for optimum fidelity and low level
detail reproduction in both the main zone as well as the second
multi-channel Zone2 system.
2. Latest Surround Decoding Technology
1) Dolby Digital
Using advanced digital audio compression and decoding
technologies, Dolby Digital provides up to 5.1 channels of wide
bandwidth, wide dynamic range multi-channel high fidelity
surround sound. Dolby Digital is the default digital multi-
channel audio delivery system for DVD and USA/Canada high
definition television systems.
2) Dolby Pro Logic IIx
Dolby Pro Logic IIx adds the ability to provide up to 7.1 channel
reproduction from conventional stereo (2 channel) sources,
including surround back reproduction with a 6.1 or 7.1 surround
sound system. Pro Logic IIx has three modes: one for movie-
based soundtracks; one for stereo music sources, and a game
mode for game consoles with stereo (2 channel) audio outputs.
3) Dolby Headphone
Developed jointly by Dolby Laboratories and Lake Technology
Ltd. of Australia, Dolby Headphone decoding provides thrilling
surround sound effects of your favorite movie and music
sources when using conventional stereo headphones.
4) DTS (Digital Theater Systems)
DTS provides up to 5.1 channels of wide-range, high fidelity
surround sound from sources such as DTS-encoded CDs,
DVDs with DTS soundtracks, and DVD-Audio discs that provide
DTS soundtracks.
5) DTS-ES Extended Surround and DTS Neo:6
The AVR-5805 also supports the DTS-ES 6.1 matrix and
discrete encoded surround formats, and also features DTS
Neo:6 stereo-to-surround decoding with both Music and Movie
modes for superb surround sound from conventional stereo
sources.
6) DTS 96/24 Decoding
Digital Theater Systems 96/24 provides ultra high resolution 24
bit, 96 kHz sampling for optimum wide bandwidth fidelity and
superb dynamic range. The AVR-5805 is equipped to faithfully
decode DTS 96/24 discs.
7) HDCD High Definition Compatible Digital
Using sophisticated encoding and decoding technologies, the
HDCD format provides improved fidelity and dynamic range
from encoded Compact Discs (which number in the thousands
of titles). The AVR-5805, via a standard digital audio connection
from a CD player or DVD player, internally recognizes and
decodes HDCD discs for optimum fidelity and widest dynamic
range.
8) Home THX Ultra2 Certified
Home THX is the unique collaboration between THX Ltd. and
audio/video equipment manufacturers. THX Ultra2 certification
is the highest performance level, and provides a rigorous set of
performance standards along with proprietary surround sound
post-processing technologies, all designed to maximize the
surround soundtrack playback experience in the home theater.
In addition, the AVR-5805 is fully compatible with THX
Surround EX, which provides extended surround sound via
additional surround back channel reproduction, first employed
on Lucasfilms’ Star Wars Episode 1 – The Phantom Menace,
and featured on many major motion pictures since. As well,
the AVR-5805’s power amplifier section fully complies with the
latest THX Ultra2 standards, and two new addition surround
modes are also provided – THX Ultra2 Cinema mode and THX
Music mode. In addition, the AVR-5805 also incorporates THX’s
new THX Games mode, for thrilling surround sound effects
from two channel game box audio sources.
3CAUTIONS ON HANDLING
•Switching the input function when input jacks are not
connected
A clicking noise may be produced if the input function is switched
when nothing is connected to the input jacks. If this happens,
either turn down the MASTER VOLUME control or connect
components to the input jacks.
•Muting of PRE OUT jacks and SPEAKER terminals
The PRE OUT jacks and SPEAKER terminals include a muting
circuit. Because of this, the output signals are greatly reduced for
several seconds after the power switch is turned on or input
function, surround mode or any other-set-up is changed. If the
volume is turned up during this time, the output will be very high
after the muting circuit stops functioning. Always wait until the
muting circuit turns off before adjusting the volume.
•Whenever the power switch is in the STANDBY state, the
apparatus is still connected on AC line voltage.
Please be sure to turn off the power switch or unplug the cord
when you leave home for, say, a vacation.
