State-of-the-art Denon Solutions for
Maximizing Content Quality
• Fully discrete, identical quality and power
for all 7 channels (135 W x 7ch)
To faithfully reproduce the original surround sound, each of
the AVR-891’s 7 channels is equipped with the same power
amp of equal power. Since these power amps also use dis-
crete circuits configured with parts strictly selected for their
contribution to high sound quality, rather than with low-cost
integrated circuits (ICs), the surround sound playback is of
impeccably high quality.
• Featuring 3D pass-through technology
By connecting a 3D-compliant Blue-ray disc player and 3D-
compliant TV to the AVR-891, you will have a 3D home the-
ater where you can enjoy high-denition sound and video on a
level you’ve never experienced before.
• Supports HDMI 1.4a with 3D, Audio Return
Channel, Deep Color, “x.v.Color” , Auto Lipsync
and HDMI control function
When you connect the AVR-891 to a TV with a single HDMI
cable, it supports Audio Return Channel (ARC)(*1) that can
play back the TV audio in surround sound. Until now, if you
wanted to enjoy surround sound from a TV, you needed to
use an optical digital cable or coaxial digital cable to bring
sound from the TV to the A/V receiver. The AVR-891’s ARC
feature, however, helps you keep cable connections neat and
out of the way as you build your home theater.
*1: The TV must also support ARC.
• High-denition audio support
The AVR-891 has a decoder that supports Dolby TrueHD and
DTS-HD Master Audio, the high resolution audio formats found
on many Blu-ray titles.
• Dolby Pro Logic IIz
To let you enjoy an even richer spatial expression, the
AVR-891 is equipped with a Dolby Pro Logic IIz processor.
By connecting Front Height speakers and using Dolby Pro
Logic IIz playback, you will be able to enjoy surround sound in
the vertical as well as horizontal direction.
• High-bit I/P Converter and Scaler up to 1080p
The AVR-891 uses a high-performance video up-scaler
to convert SD (standard denition) video material to HD (high
denition) quality. This means that the 480i/480p (SD-quality)
video signals of DVD programs and other material are converted
to the high-quality 1080p signal of HD video, and output to the
HDMI port. The fuzziness in the details of SD video is removed
to produce a clear picture. Now you can enjoy not only your
DVDs but also your VCR tapes and games with much greater
clarity and detail.
• Minimum Signal Path for clear audio and video
signal
The “simple and straight” design concept has been thoroughly
implemented in the signal paths to contribute to immaculately
clean audio and video playback. Signal paths are as short as
possible to keep signal degradation in the audio and video
circuitry to an absolute minimum
• Direct Mechanical Ground Construction, em-
bodying concepts for thorough vibration resistance
Vibration-resistant construction has been reviewed to
thoroughly suppress the adverse influences of vibration on
sound quality. The power transformers, a source of vibration,
have been securely mounted on the highly rigid bottom chassis.
Direct mounting of cast-iron feet to the radiator in near proximity
to each other serves to suppress mutual vibration with the
power transformers and other sources of vibration.
Connectivity & Future-ready Expandability
• 6 x HDMI in / 1 x HDMI out (Repeater)
• Direct play for iPod and iPhone via USB
You can also listen to music files from your iPod by simply
connecting it to the AVR-891’s USB port with the USB cable
that came with the iPod. To start play, just press the iPod Play
button on the AVR-891 or its remote control unit. Digital sig-
nals from the iPod are transmitted as is to the AVR-891 where
they pass through the compressed audio restorer and are
processed by advanced audio circuitry to produce a clean,
high-quality sound.
•Dock connectivity for iPod and network streaming
Network music can be enjoyed via the Denon Networked Control
Dock. (Requires optional ASD-51W or ASD-51N dock.)
•Power Amp Assign function, for versatility in
using the AVR-891 for dierent purposes
The AVR-891 supports up to 7.2 channels (FL/ FR/ C/ SL/
SR/ SBL/ SBR/ SW1/ SW2) for surround playback defined
by the Blu-ray disc format. To enjoy surround playback with
the AVR-891’s Dolby Pro Logic IIz, you can reassign the power
amp from the two surround back channels (SBL/SBR) to the
two front high channels (FHL/FHR). Or by assigning the SBL/
SBR power amp to Zone 2, you can enjoy multi-room audio
playback, or to achieve higher-quality sound for 2-channel ste-
reo playback, you can configure the AVR-891 for front bi-amp
operation. These are just some of the ways you can arrange the
AVR-891’s amps to suit various listening styles.
Ease-of-use
• On-Board GUI via HDMI output (up to 1080p)
The AVR-891 is equipped with an easy-to-view Graphical
User Interface (GUI) featuring visual menu displays. These
menu displays can also be output to the monitor over HDMI.
• Newly developed pre-memory remote control hand-
set with Glo-Key buttons
• Remote Setup Guidance via On-Screen Display
• Three Quick Select buttons
• Auto surround mode
• Sleep timer function
• Audio Delay function (max. 6 frames or 200 mSec)
• Muting level settings (Full/-40dB/-20dB)
• Audio level memory, capable of correcting
dierent signal levels for each input device
• Variable subwoofer crossover switching
