FEATURES
• Switching the input function when input jacks are not
connected
A clicking noise may be produced if the input function is switched
when nothing is connected to the input jacks. If this happens, either
turn down the MASTER VOLUME control or connect components
to the input jacks.
• Muting of PRE OUT jacks, HEADPHONE jack and SPEAKER
terminals
The PRE OUT jacks, HEADPHONE jacks and SPEAKER terminals
include a muting circuit. Because of this, the output signals are
greatly reduced for several seconds after the power switch is
turned on or input function, surround mode or any other-set-up is
changed. If the volume is turned up during this time, the output will
be very high after the muting circuit stops functioning. Always wait
until the muting circuit turns off before adjusting the volume.
• Whenever the power switch is in the STANDBY state, the
apparatus is still connected on AC line voltage.
Please be sure to unplug the cord when you leave home for,
say, a vacation.
1. Digital Surround Sound Decoding
Featuring 32 bit high speed DSP, operating entirely in digital
domain, surround sound from digital sources such as DVD, LD,
DTV and satellite are faithfully re-created.
2. Dolby Digital
Using advanced digital processing algorithms, Dolby Digital
provides up to 5.1 channels of wide-range, high fidelity surround
sound. Dolby Digital is the default digital audio delivery system for
North American DVD and DTV.
3. DTS (Digital Theater Systems)
DTS provides up to 5.1 channels of wide-range, high fidelity
surround sound, from sources such as laser disc, DVD and
specially-encoded music discs.
4. DTS-ES Extended Surround and DTS Neo:6
The AVR-3801 is compatible with DTS-ES Extended Surround, a new
multi-channel format developed by Digital Theater Systems Inc.
The AVR-3801 is also compatible with DTS Neo:6, a surround mode
allowing 6.1-channel playback of regular stereo sources.
5. Wide screen mode for a 7.1-channel sound even with
5.1-channel sources
DENON has developed a wide screen mode with a new design
which recreates the effects of the multi surround speakers in
movie theaters. The result is 7.1-channel sound taking full
advantage of surround back speakers, even with Dolby Pro Logic
or Dolby Digital/DTS 5.1-channel signals.
6. 24 bit D/A Conversion
All six channels, including the five main channels and the low
frequency effects (LFE) channel benefit from reference, for
optimum high fidelity reproduction of music and movie
soundtracks.
7. Dual Surround Speaker Mode
Provides for the first time the ability to optimize surround sound
reproduction using two different types of surround sound speakers
as well as two different surround speaker positions:
(1) Movie Surround
Motion picture soundtracks use the surround channel(s) to
provide the ambient elements of the acoustic environment they
want the audience to realize. This is best accomplished by the
use of specially-designed surround speakers that offer a wide
diffusion pattern (bipolar dispersion) or by using surround
speakers that provide broad dispersion with a minimum of on-
axis localization (dipolar dispersion). Side wall mounting (closer
to the ceiling) of the surround speakers provides the greatest
envelopment, minimizing localization of direct sound from the
speakers.
(2) Music Surround
With full range discrete surround channels, as well as three
discrete full range front channels, digital formats such as Dolby
and DTS offer thrilling surround sound music listening.
Producers of multi-channel discrete digital music recordings
almost always favor the use of direct radiating (monopolar)
surround speakers, placed in the rear corners of the room,
since that is how they configure their studios during the
mixing/creation process.
The DENON AVR-3801 provides the ability to connect two
different sets of surround speakers, and place them in the
appropriate locations in your AV theater room, so that you can
enjoy both movie soundtracks and music listening, with
optimum results and no compromise.
8. Component Video Switching
In addition to composite video and “S” video switching, the AVR-
3801 provides 2 sets of component video (Y, C
B, CR) inputs for the
DVD and TV/DBS inputs, and one set of component video outputs
to the television, for superior picture quality.
9. Video Select Function
Allow you to watch one source (visual) while listening to another
source (audio).
10.Future Sound Format Upgrade Capability via Eight Channel
Inputs & Outputs
For future multi-channel audio format(s), the AVR-3801 is provided
with 7.1 channel (seven main channels, plus one low frequency
effects channel) inputs, along with a full set of 7.1 channel pre-amp
outputs, controlled by the 8 channel master volume control. This
assures future upgrade possibilities for any future multi-channel
sound format.
