Denon AVR-1083 User manual

Dolby Digital EX / DTS-ES and DTS 96/24 with 7ch Power Amps and Multi-room Flexibility
Dolby Digital EX and dts 96/24 have been added to offer full support for all encoded surround formats, and the D.D.S.C has been vastly
i mproved through the use of the new Analog Devices Melody 100 DSP processor. The AVR-1 083 is the first receiver in its class to offer compo-
nent video conversion for increased flexibility and ease of installation.
•

Fully Discrete, Equal Power Seven Amplifier Channels, 150 Watts Each
The AVR-1083 features an equal power 7-channel amplifier section, with identical
amplifier design on all 7 channels, with high current discrete output devices on all
channels. Each of the 7 amplifier channels is rated at 150 watts, into 6 ohms,
1 kHz with no more than 0.7% THD.
•

Finest DSP employed for faster processing in the D.D.S.C-Digital circuitry
and higher sound quality
•

32-bit Floating Point DSP
Hammerhead Shark (MELODY100), the latest DSP from Analog Devices, is
used for the decoder to further boost digital signal processing capability and also
providing the highest dynamic range. Faster processing speed results in more
complete surround decoding.
•

24-bit, 192-kHz All-channels D/A Conversion
For optimum fidelity and transparency, the AVR-1083 features a total of 16 Burr-
Brown PCM-1791 high resolution 24-bit, 192 kHz DACs, in an eight channel
differential mode configuration.
•

24-bit, 192-kHz Digital Interface Receiver
The AVR-1083 includes a Digital Interface Receiver (DIR) 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.
•

24-bit, 192-kHz A/D Conversion
The AVR-1083 is capable of 24-bit, 192-kHz A/D conversion, improving S/N and
dynamic range by approximately 10 dB.
•

DENON's Latest Surround Technology Faithfully Recreates the Surround
Sound Produced at the Dubbing Stage.
•

DTS 96/24 5.1 Decoding for DVD-Video
High-quality 96-kHz, 24-bit (96/24) sound playback from ordinary DVD-Video
recordings is limited to only two channels and there are also limitations on the
picture. DVD-Video recorded in DTS 96/24, however, allows high-quality
5.1-channel sound playback in full-quality, full-motion video.
•

DTS-ES Discrete 6.1 and Matrix 6.1
The AVR-1 083 is equipped with a DTS-ES decoder that supports Discrete 6.1
and Matrix 6.1. Discrete 6.1 faithfully reproduces program sources originally
recorded in 6.1-channel sound, and Matrix 6.1 performs matrix processing on the
Left Surround and Right Surround signals and brings out Back Surround channels.
•

DTS NEO:6
DTS NEO:6 lets you enjoy 2-channel analog, PCM, and Dolby Digital
2-channel sources in full 6.1-channel surround sound.
•

Dolby Digital EX
Dolby Digital EX, a 6-channel surround format proposed by Dolby
Laboratories, was jointly developed by Dolby Laboratories and LucasFilm
Ltd. to bring the dynamic wealth of Dolby Digital Surround EX into the
home. The warm playback of 6.1 channels which include surround back
channels enables easy positioning of sound images directly behind the
li
stener, dramatically improving the spatial expressiveness of the
surround field.
•

Dolby Pro Logic II
With the AVR-1 083, you can use Dolby Pro Logic II to do more than just
enjoy your 2-channel analog, PCM, and Dolby Digital 2-channel sources in
surround sound ambiance.
•

Auto Surround
The AVR-1 083 can automatically store the surround mode for any of four input
signals: (1) Analog and PCM 2 channel, (2) Bit stream 2-channel (Dolby Digital,
DTS) and (3) Bit stream multi-channel. If the type of input signal changes, the
most appropriate surround mode is automatically selected for the signal.
∎ Component Video Conversion, the first time in this class
•

High-grade Up Conversion
The AVR-1083 is the first model in the mid price range to include the Video Up
Conversion feature that converts video signals to component signals, letting you
enjoy high picture quality from all video gear connected to the AVR-1 083. Since
composite and S-video signals are also converted into component video signals
and output to the monitor, all you need to do is connect a monitor that can display
component video images.
•

Broad frequency range up to 100 MHz
The AVR-1083 is equipped with 2 sets of component inputs and 1 set of monitor
outputs (all RCA terminals). A high-performance relay is used to switch signals,
and a high frequency range up to 100 MHz is supported.
Front 150 W + 150 W (6 ohms, 1 kHz, 0.7
% THD)
Center 150 W (6 ohms, 1 kHz, 0.7 % THD)
Surround 150 W + 150 W (6 ohms, 1 kHz, 0.7 % THD)
Surround back 150 W + 150 W (6 ohms, 1 kHz, 0.7 % THD)

∎
Pure Direct mode which is equipped with
AL24 processing, to enjoy
purely stereo music
with high sound quality
The Pure Direct mode lets you use the AVR-1083 as a high sound quality stereo
amplifier. A simple key operation on the main unit to select Pure Direct automatically
turns off power to the video circuitry and the fluorescent lights also go off to thoroughly
minimize adverse influences from these circuits on the audio circuit. During analog
audio input, power to the digital circuitry is also turned off. Furthermore, Denon's
AL24 processor for high sound quality has been added to the front 2 channels
during digital audio input, enabling the playback of sound with remarkably high
transparency.


Hefty Power Transformer for Stable Supply of Power
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 AVR-1083 boasts high output
power of 110 W for each of the 7 channels.
•

Newly-developed block capacitor
A new, large-capacity block capacitor was developed for the AVR-1083 to ensure
a rock stable supply of power.
• Newly redesigned pre-programmed remote controller with learning feature
The AVR-1083 comes with a newly-developed remote controller with the most
frequently used keys layed out in the center and an easy-to-grip shape and size.
I t also has a small liquid crystal display that lets you quickly identify which devices
you are controlling at a glance.

Support for Multi Zone Configurations
• The AVR-1083 provides a Multi Zone Output function and a Select function that
l et 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
variable pre-amp output along with composite video feed. The AVR-1083'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 150 Watts per channel output power, while still providing 5
discrete amplifier channels to drive all speakers in a 5.1 configured home theater
room.

or outboard video processor.

S/N in the useable area has been improved. Finer adjustments are also possible
i n 0.5 dB steps across the extended range of -80 dB to +18 dB.
•

Adjustable Cross-Over Switching
The AVR-1083 supports subwoofer cross-over switching with a choice of 5 cross-over
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.
