Denon AVR-1905 - Manual

DTS-ES Discrete 6.1 and Dolby Digital EX with Power Amps for 7 Channels
■ High-Quality Sound Reproduction
• NEW High Resolution 32bit Floating Point DSP
• 96 kHz Processing Circuit
• 24 bit,
192 kHz High Resolution D/A Conversion
■ Component Video Conversion
• High-grade Up Conversion
This video transcoding technology lets you enjoy highest picture quality from all video
gear connected to the AVR-1905. Since composite and S-video signals are converted
up to component video signals and output to the monitor, all you need to do is con-
nect a monitor that can display component video images.
• 3 Sets of Component Video Inputs
The AVR- 1905 is equipped with 3 sets of assignable, component video inputs and
1set of monitor outputs (all RCA terminals)
• High Definition Quality Video Switching
The high-performance relay that is used to switch component video signals, features
an extended bandwidth range up to 100 MHz.
■ DENON's Basic Design for High-Quality Sound Reproduction
• Power Transformer for High Power Driven
The chassis that supports the large transformer has been
designed to absorb vibration, and the transformer is housed
inside a highly rigid frame to secure it more solidly to the chassis.
In addition, a cushioning material has been placed around the
core of the transformer to minimize interference on the signal
and enable more faithful reproduction of the original sound.
The AVR-1905 inherits th
is low-noise design from the higher-end
models , like the acclaimed AVR-3805.
• Twin Drive Rectifier
DENON's Twin Drive Rectifier design uses two rectifying diodes in
parallel to bring out the maximum potential of the large transformer.
Since the rectifiers recharge the large block capacitors at low
impedance, they are able to supply ample current to
accurately
reproduce deep bass as well as sudden bursts of sound
from percussion or other musical instruments.
• Large Aluminum Extruded Heatsink
DENON uses a large heatsink made of extruded aluminum. It is
placed in a design that ensures mostly uniform temperatures
throughout the heatsink. This will ensures that all channels
respond with equal performance to the demands of the audio
signals.
■ Fully Discrete, Equal Power Six Amplifier Channels, 90 Watts Each
Front 80 W + 80 W (8 ohms, 20 Hz - 20 kHz, 0.08 % THD)
Center 80 W (8 ohms, 20 Hz - 20 kHz, 0.08 % THD)
Surround 80 W + 80 W (8 ohms, 20 Hz - 20 kHz, 0.08 % THD)
Surround Back 80 W + 80 W (8 ohms, 20 Hz - 20 kHz, 0.08 % THD)
For optimum Dolby Digital and dts reproduction, the AVR-1905 features high quality,
wideband audio amplification, providing 90 watts power output for each of the six main
channels. A large capacity power supply includes a high current power transformer
along with discrete power output devices on all six amplifier channels for highest dynamic
range and superb reproduction clarity.
■ Wide-Range Play Capability for DVD-Audio and Super Audio CD
The power amp circuits of the AVR-1905 have been meticulously designed to reproduce
the exceptionally high sound quality with wide frequency response from 10 Hz to 100 kHz.
■ Dual-Channel Surround Back Power Amps for 7.1 Surround
The AVR-1905 is equipped with a total of 7 power amps including two for the Surround
Back channel speaker s to give you more clearly defined sound localization at the rear for
6.1-channel surround sources such as DTS-ES Discrete 6.1, DTS-ES Matrix 6.1, Dolby
Digital EX
, Dolby Por Logic IIx, and DTS-ES NEO:6.
■ Cinema Equalizer
The sound from movie sources recorded in Dolby Digital, DTS or other
formats emphasizes high-frequency range due to a theater’s front speakers being
placed behind the movie screen. If this sound is reproduced in the home theater
without correction, the high-frequency range is too strong. The AVR-1905 features a
Cinema Equalizer to correct these high-frequency components so that the sound is
clearer and easier to listen to. (For Dolby Digital, Dolby Pro Logic II,
Dolby Digital EX and DTS surround modes)
■ Personal Memory Plus, for Easy Operation
The AVR-1905 includes the Personal Memory Plus function that automatically
remembers the surround mode you last used for each program source, so that you do not
need to select the mode again for that program.
■ On Screen Display
The AVR-1905 lets you make system settings via diaplays on your TV screen from the
comfort of your chair.
■ Acclaimed Customization Feature
As with all of DENON’s high-grade A/V receiver
s, the AVR-1905 lets you adjust delay
times and other parameters so that you can customize the performance of the AVR-1905
to suit your own home theater and enhance operating ease. These customized features
are then stored, for each source input and surround mode, in Personal Memory Plus so
constant readjustments are not required.
