3. Movie & Music Surround For The Whole House
The AVC-A1XVA's versatile Multi Source functions let you select
different audio and video sources for each room in your home.
Different audio and video multi-channel sources can be enjoyed in
the home theater (Main room), as well as a multi-channel audio
and video source directed to a second room. Additional zones (3
and 4) can also receive video and stereo audio as well. The AVC-
A1XVA features Freely Assignable Ten Power Amp Channels, so
that you can decide which power amp channels can be dedicated
to the MAIN ZONE, the secondary zone (ZONE2) as well as to two
additional zones (ZONE3 and ZONE4), as well as providing line
level outputs to external power amplifiers.
1) ZONE2 Theater Capability
With up to 9.1 system in the main home theater room, the
AVC-A1XVA provides for a second, fully 5.1 capable system in
ZONE2, with component video and five amplifier channels as
well, with video up-conversion if desired.
2) ZONE3 Independent Audio & Video
The AVC-A1XVA provides the ability for a third independent
zone, with selectable audio and video sources.
3) ZONE4 Independent Audio
ZONE4 is ideal for a room where you can enjoy a different
stereo source, for background music listening.
4. Ten High Power Assignable Power Amplifiers
1) Featuring high current, THX-certified high power amplifier
channels, the AVC-A1XVA is equipped to drive high
performance loudspeakers with unprecedented dynamic range
and low impedance drive capability, with each of the ten
amplifier channels rated at 170 W into 8 Ω/ohms. Each channel
can be freely assigned to the main home theater room, as well
as assigned to additional zones for multi-channel or stereo or
even monophonic distributed audio/video and audio-only
functions. For example, you might choose to have seven
amplifier channels dedicated to a full THX Surround EX & DTS
Surround EX 7.1 channel system in the main room, while still
allowing a powered stereo function in the second zone, and a
third monophonic background music function in another room.
Or, you could have a principal 5.1 channel setup in the main
home theater room, while having a secondary powered 5.1
system in the second zone. You could even have (with
compatible bi-amplified-capable speakers) a true 5.1 bi-amped
system in the main room, along with additional line-level-
powered systems in up to three additional rooms.
5. Audiophile Audio Quality Throughout
1) Separated Pure Audio & Video Chassis Construction
For optimum audio and video quality, the AVC-A1XVA features
dedicated and physically separated low and high level audio
and video circuits to prevent degrading mutual interference.
2) Optimum Chassis Stability
As the AVC-A1XVA is equipped with a massive toroidal main
power supply and additional secondary power supplies,
centrally located within the chassis, a fifth chassis foot helps
reduce the physical vibration that can cause mechanically-
induced vibration-related distortions.
3) Multiple Separate Power Supply Topologies
No less than six individual power transformers (one very large
toroidal unit, and five additional lower voltage power
transformer units) are provided, ensuring that each critical sub-
section draws power from its own dedicated supply,
eliminating minute fluctuations that occur with single
transformer-equipped competitive units.
4) Multiple Toroidal Sub-Windings
The massive main toroidal power transformer (which powers
the ten amplifier channels block) features dedicated sub-
windings and high current, ultra stable DC rectifiers and high
rated smoothing/storage capacitors, with a tremendous
132,000 µF total storage capacity.
5) Pure Direct Mode
According to the selected input source, the Pure Direct Mode
provides the optimum decoding by switching off any and all
unnecessary processing (video disable, tone bybass, and other
unnecessary circuits).
6) Dual Surround Speaker Mode
DENON was the first to introduce Dual Surround Mode
Speaker Switching, where two different types (and positions)
of surround speakers could be chosen according to the source
material – diffuse surround speakers located at the sides of the
listening position for movie surround sound, and directional
surround speakers located at the room's rear corners for music
surround sound. The AVC-A1XVA also adds the ability to have
both powered (AVC-A1XVA amplified) music and surround
sound speaker systems, according to each individual home
theater's setup circumstances.
7) Highest Quality Input & Output Terminals
The AVC-A1XVA audio and video input terminals are gold-
plated, as are the ten speaker terminal pairs.
6. High Resolution Video Section
1) Component Video Switching
In addition to composite and S-Video switching, the AVC-
A1XVA provides no less than five sets of component video
inputs via RCA-type coaxial connectors, as well as an additional
sixth set of component video inputs via BNC connectors, as
well as two sets of component video outputs (one for RCA-
type coaxial, one for BNC connectors), with additional
capability for component video output to ZONE2. These
component video circuits are fully HD-compatible, with a flat
response to 100 MHz, far above the 38 MHz requirement for
true HD reproduction, ensuring crisp and clear HDTV picture
quality.
2) Video Up And Down Conversion Function
To eliminate video signal incompatibility, the AVC-A1XVA is
equipped with video up-conversion and down-conversion.
Composite and S-Video signals are internally up-converted to
component video for the MAIN ZONE, and down-converted for
480i component video signals. ZONE2 features down-
conversion from S-Video to composite video.
3) Progressive Scanning & Scaling Function
Via high quality Faroudja DCDi™ (*1) processing, the AVC-
A1XVA converts standard definition interlaced video to higher
resolution progressive scanning format – 480i interlace to 480p
progressive. For non-copy-protected video signals, further up-
conversion to HD 1080i video is also provided, for highest
visual quality with compatible HD video displays.
4) High Resolution 12 bit/216 MHz Video D/A Conversion
Featuring Analog Devices ADV-7310 Noise Shaped Video (*2)
digital-to-analog converters, the AVC-A1XVA provides superior
high resolution video output free from video noise and
conversion artifacts.
5) Superior S-Video Processing
A 3-dimensional Y-C separation circuit provides artifact-free
composite video to S-Video up-conversion, and Time Base
Correction for optimum color sharpness with composite video
inputs (MAIN ZONE).
7. Latest Digital A/V Input/Output Capability With Future Upgrade
Ability
1) HDMI/DVI Switching
High-Definition Multimedia Interface provides digital audio and
video signal transfer between source components, the AVC-
A1XVA, and compatible video displays with HDMI digital
interface. Digital Visual Interface provides similar digital
input/output capability for digital video signals. The AVC-A1XVA
is equipped with three HDMI inputs and one DVI input, and
one each HDMI and DVI outputs to compatible video displays.
Each HDMI/DVI input feeds both HDMI and DVI outputs, for
optimum compatibility with today's HDMI- and DVI-equipped
video displays.
