Inputs and Outputs Notes
Power Supply: The
AVR-3803 is designed and constructed for the highest quality sound. A huge power
transformer has been connected in the power section where it is combined with a
rectifier diode and a large block capacitor to ensure a large, stable supply of
electrical current. Accordingly, the receiver boasts high output power of 110
watts for each of the 7 channels.
Digital Surround Processing: The
AVR-3803 features the new Analog Devices Melody 100 (Hammerhead SHARC) 32-bit
floating point, high speed digital surround processor, operating entirely in the
digital domain, to deliver accurate performance from digital sources such as
DVD, LD, and DTV.
Digital-to-Analog Conversion: Two Burr
Brown linear PCM-1791 24-bit/192kHz high-resolution DACs are included for each channel, giving the
AVR-3803 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.
Analog-to-Digital Conversion: The
capable of 24-bit/192kHz A/D conversion, allowing it to provide especially accurate signal conversion. Analog to digital signal conversion is not applied to analog signals received by the 7.1 multi-channel inputs; analog signals received by the 7.1 multi-channel inputs are sent directly to the speaker and preamp outputs.
24-bit/192kHz Digital Interface
Receiver: The AVR-3803 includes a Digital Interface Receiver that
distinguishes various types of digital input signals, including 24/192 and 24/96
stereo PCM signals, performs the appropriate signal processing, and transmits
the information to the DSP block.
Surround Modes: This
receiver incorporates a wide variety of surround modes to bring you maximum
enjoyment from your audio and video software. The surround modes include:
- Dolby Digital Surround EX
- Dolby Digital (5.1)
- Dolby Pro Logic II (Music,
Cinema and Emulation)
- DTS-ES Discrete (6.1)
- DTS-ES Matrix (6.1)
- DTS (5.1)
- DTS Neo:6 (Cinema & Music)
- DTS-ES 96/24
- 5/7-Channel Stereo
- Wide Screen
- Super Stadium
- Rock Arena
- Jazz Club
- Classic Concert
- Mono Movie
- Video Game
Wide Screen Mode: Denon has
developed a Wide Screen mode which recreates the effects of the multiple
surround speakers found in movie theaters. The result is 7.1-channel sound
taking full advantage of the surround back speakers, even with Dolby Pro Logic
or Dolby Digital/DTS 5.1-channel signals.
DTS 96/24: The AVR-3803 can
decode DVD-Video software recorded in DTS 96/24, which allows high-quality
24-bit, 96kHz audio playback in all channels with full-quality, full-motion
video. High resolution 96/24 audio playback from ordinary DVD-Video recordings
is limited to only two channels with some limitations on the picture.
Processing: The AVR-3803 includes Denon's
renowned 24-bit ALPHA processing technology that
reproduces digital signals in a waveform with the smoothness
of analog signals. This technology thoroughly suppresses annoying
quantization distortion and faithfully reproduces the delicate musical
details of low-level signals. ALPHA 24 processing works in 2-channel Stereo,
Direct, Pure Direct modes.
Mode: In addition to surround sound playback,
the AVR-3803 lets you enjoy pure 2-channel stereo
sound as well through its Pure Direct mode. In Pure
Direct mode, power to the video circuitry and the front panel display
is turned off to thoroughly minimize adverse influences from these circuits on
the audio circuits. During analog audio input, power to the digital circuitry
is also automatically turned off. Furthermore, Denon's AL24 processing is added
to the 2 front channels during 2-channel linear
PCM input, enabling the playback of sound with remarkably high transparency.
Direct Mode: Similar to the
Pure Direct mode, the Direct mode allows you to achieve good quality 2-channel
sound while watching images. In this mode, audio signals bypass such circuits as
the tone circuit and are transmitted directly.
Dual Surround Speaker Mode: The
AVR-3803 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. With movie soundtracks, a set of dipole/bipole
surround speakers mounted on a side wall close to the ceiling may provide the
best results. With music, the use of direct radiating surround speakers mounted
in the rear corners of the room more closely resembles the configuration of
5/7 Channel Stereo: The front left channel signals are
output to the surround and surround back signal left channels, the front
right channel signals are output to the
surround and surround back signal right channels, and the in-phase component
of the left and right channels is output to the
center channel. This mode can be used to enjoy stereo sound from all
speakers in the room.
Volume Control: The
receiver's volume control allows you to make fine adjustments of 0.5dB in an
extended useable range of -80dB to +18dB. In addition, the signal-to-noise ratio
in the useable area has been improved.
The AVR-3803 provides a Multi-Zone Output function and a
Select function that let you output different
sources to multiple zones. Sources can be selected for
output to an additional zone, in addition to the main room. Multi-room
Zone 2 can have fixed or variable pre-amp output along with a
composite video feed. The
AVR-3803's Power Amplifier Assign function lets you assign the 2 Surround
Back (SB L/R) amplifier channels when the system is not configured for 7.1 to instead drive the Multi-room Zone
2 speakers with 110 Watts per channel output power,
while still providing 5 discrete amplifier channels to drive all speakers in a
5.1 configured home theater room.
Component Video Switching: In
addition to composite and S-video switching, this receiver has two sets of
component video inputs and one set of component video (monitor) outputs. Each of
the component video inputs is assignable to different input sources. A
high-performance relay is used to switch signals, and a high-frequency range of
up to 100MHz is supported, giving it the ability to pass HDTV signals.
Video Conversion Function: The
AVR-3803 is capable of up-converting video signals, allowing the highest picture
quality available from all connected video gear. Video signals input along
composite video cables are output from the composite, S-video, and component
video monitor outputs. Signals input by S-video cables are output from the
composite, S-video and component video monitor outputs. Down-converting from
component video signal to S-video or composite is not possible.
Display (OSD): An OSD can be displayed on
your television for easy system setup. Depending upon the OSD Setup mode, the
OSD can be displayed from the composite, S-video and component video monitor
Multi-Channel Inputs: The AVR-3803 is equipped with a 7.1-channel
wideband (up to 100kHz) input to accommodate present and future multi-channel formats, such
as DVD-Audio or SACD.
Selectable Crossover Setting: This
receiver supports subwoofer crossover switching with a choice of 5 frequencies:
40, 60, 80, 100, and 120 Hz. This lets you more accurately match the performance
characteristics of the subwoofer to the main speaker system.
Audio Delay: While watching a
DVD or other video source, the picture on the monitor may seem delayed with
respect to the sound. When this happens, you can adjust the audio delay to delay
the sound and synchronize it with the picture.
Personal Memory Plus: The
Personal Memory Plus function automatically memorizes the surround modes and
input modes selected for the different input sources. When an input source is
selected, the modes stored in memory for that source are automatically recalled.
The surround parameters, tone control settings and playback level balance for
the different output channels are memorized for each surround mode.
Multibrand A/V Learning Remote
(RC-921): The AVR-3803 comes with a newly-developed, fully-backlit,
infrared remote control with a small LCD screen and the most frequently used
keys in the center. It is pre-programmed to control the receiver and other Denon
A/V components. In addition, the remote is pre-coded for multiple brands of CD
players and recorders, MiniDisc player/recorders, DBS Satellite receivers, VCRs,
Cable boxes, TVs, DVDs, Laserdiscs, and Cassette recorders. The remote can also
"learn" the codes of other remotes if that component is not included
in the Denon remote's library of preset memory codes.
System Call (Macros): This
remote can be programmed to transmit a series of commands with a push of a
single button. For example, you can program the remote to turn on the receiver's
power, select the input source, turn on the monitor TV's power, turn on the
source component's power, and command the source component to begin playback,
all with one push of a button. You can program up to 10 commands each into the
remote's "Call 1" and "Call 2" buttons.
Serial Control/Room-to-Room Ports: The
AVR-3803 has a mini-jack input for a connection to an external remote control
system, such as AMX or Crestron. If you are using a Denon RC-616 Infrared
Re-transmitter, you can connect the inputs and outputs directly to the receiver
using the room-to-room mini-jack inputs.
Speaker Outputs: The
AVR-3803 has nine speaker outputs for Front left and right, Center, Surround A
left and right, Surround B left and right, and Surround Back/Zone 2 left and
right. All speaker outputs have binding post connectors, allowing you to connect
the speakers with bare wire, banana plugs or pin connectors. The binding posts
are spaced too far apart to support dual banana plugs, and the collar
surrounding each post prevents the use of spade lugs.
Dual Surround Speakers: As
mentioned above, this unit offers A and B surround speaker outputs. This allows
you to connect two sets of surround speakers, placing them in different
locations in the room, to optimize the music and movie experiences separately.
In the menu, you can choose to use Surround A or B, or Surround A + B. Note: The
minimum impedance for Surround A or B is 6 ohms, and for Surround A + B is 8
Digital Inputs/Outputs: This
receiver has 7 assignable digital inputs and 2 digital outputs. There are 5
optical digital inputs, with two of them (Opt 4 and Opt 5) coupled with an
optical digital output. There are also 2 coaxial digital inputs. Each digital
input can be "assigned" to a different input source, or turned off if
not in use.
Pre-out Jacks: This receiver
has a total of 10 pre-out level RCA jacks for the following channels: Front left
and right, Center, Subwoofer, Surround left and right, Surround Back/Zone 2 left
and right, and Zone 2 left and right. These jacks allow you to connect the
outputs to integrated amplifiers or powered speakers. Note: When the
Power Amp Assignment for the Surround Back channels is set to "Zone
2", the pre-out signal for the selected Zone 2 source is output through the
Surround Back/Zone left and right outputs. When the Power Amp Assignment is set
to "Surround Back", the pre-out signal for the selected Zone 2 source
is output through the Zone 2 left and right outputs.
Headphone Jack: This unit has a
gold-plated standard 1/4" headphone jack on the front panel. When
headphones are plugged into the headphones jack, the speaker-level and pre-amp
level outputs are automatically turned off.
12V Trigger Output: The
AVR-3803 has a mini-jack output to send a 12-Volt DC "turn-on" signal
to another component that accepts a 12V trigger, such as a power amplifier. The
12V trigger output can be assigned to as many source inputs as desired.
