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.
are three 2-channel playback modes exclusively for music:
- Pure Direct:
plays back music with an extremely high level of sound quality. All the
video-related circuits are turned off so that music signals are reproduced
with high quality. When an analog mode is selected, the digital processing
circuits are also turned off to achieve the highest purity.
- Direct: audio
signals bypass the tone control circuits, and are transmitted directly,
resulting in good quality sound.
allows you to adjust the tone to achieve the desired sound while watching
Decoding: The AVR-3805 automatically detects
and decodes the digital bitstream from a CD that has been encoded through the
special High Definition Compatible Digital (HDCD) process. HDCD discs use 20-bit
encoding and other proprietary processing to provide the ultimate in CD
This receiver features the Denon Link (3rd edition), an RJ-45 jack on the back panel, which
allows a one-cable connection to a compatible Denon DVD player equipped with a
Denon Link connector. This digital connection allows the input of uncompressed
Super Audio CD and DVD-Audio digital signals with jitter-less data transfer and
24-Bit, 192 kHz D/A
The AVR-3805 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 recordings.
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
Auto Setup/Room EQ:
The receiver is equipped with an Auto Setup and Room Equalization function, to
achieve the most ideal sound field for your room. With the optional DM-S305
microphone (item # 033DMS305) placed at the listening position, the 32-point DSP
automatically and accurately analyzes, adjusts and sets the speaker
configurations of your system. The receiver also analyzes and adjusts the
frequency response of the speakers to the room with an 8-band parametric
equalizer. You can also manually adjust the 8-band equalizer from -6dB to +6dB
in 0.5dB steps at 63Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz and 8kHz.
can adjust the cutoff frequency of the subwoofer output from 40Hz, 60Hz, 80Hz,
100Hz, 120Hz, 150Hz, 200Hz or 250Hz.
can set the amount of attenuation for the audio muting circuit from -40dB or
-20dB from the present volume level.
Dual Surround Speaker Mode:
The AVR-3805 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:
This unit provides a Multi-Zone Output function and a Select function that let
you output different sources to multiple zones. Multi-room Zone 2 can have a
pre-amp output along with a composite video feed. You can make the Zone 2
Pre-amp output variable or set to -40dB or 0dB. Multi-room Zone 3 can have an
independently selected audio source output with a fixed pre-amp output. The
receiver's Power Amplifier Assign function lets you assign the 2 Surround Back
amplifier channels to instead drive a pair of speakers in Multi-room Zone 2 or 3
with 120 watts per channel. When the amplifier channels are assigned to Zone 2
or 3, the receiver can still provide 5 discrete amplifier channels to drive all
speakers in a 5.1-channel surround configuration.
Video Up Conversion:
The receiver's video transcoding technology converts composite and S-Video
signals to component video signals and output to the monitor. This allows you to
enjoy the highest picture quality from all video gear connected to the receiver.
In addition, composite video signals are up converted to S-Video and S-Video
signals are down converted to composite for connecting convenience.
HD Video Switching: The
unit has three assignable component video inputs and a high-performance relay
that is used to switch the signals. The switcher has an extended bandwidth range
of up to 100 MHz, making it compatible with progressive DVD (480p) and HDTV
formats (720p and 1080i).
AVR-3805 comes with a unique EL backlight touch panel remote control which can
operate the receiver as well as other remote control capable Denon components. In addition, the remote is pre-programmed with control signals for other
brands of products, including cable boxes, CD players, TVs, Cassette decks,
Laserdisc, DBS, VCRs, CD recorders, Minidiscs, DVD players and DVD recorders.
The RC-969 is also a learning remote. The remote features two large touch panels
with Electro-Luminescent backlit touch zones, and automatically activates the
backlighting when the remote is picked up, displaying only the keys required by
the device. Only the Power, Channel select, Volume Control, Cursor ring and
Enter functions are assigned to traditional push buttons.
The remote control is equipped with "System
Call" functions, allowing a series of remote control signals to be
transmitted by pressing a single button. Up to 12 sequential signals can be
stored in each of the 6 System Call buttons.
