State-of-the-art Denon Solutions for
Maximizing Content Quality
• Fully discrete, identical quality and power 
for all 5 channels (120 W x 5 ch)
To faithfully reproduce the original surround sound, each of 
the AVR-591’s 5 channels is equipped with the same power 
amp of equal power. Since these power amps also use 
discrete 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-591, you will have a 3D home 
theatre where you can enjoy high-definition sound and video 
on a level you’ve never experienced before.
• Suppor ts HDMI 1.4a with 3D, Audio Return 
Channel, Deep Color, “x.v.Color” , Auto Lipsync 
and HDMI control function
When you connect the AVR-591 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-591’s ARC feature, how-
ever, helps you keep cable connections neat and out of the 
way as you build your home theatre.
*1: The TV must also support ARC.
• High-definition audio support
The AVR-591 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 richersurround sound experi-
ence, the AVR-591 is equipped with a Dolby Pro Logic IIz 
processor. By adding a separate 2-channel power amp to the 
AVR-591’s pre-out port and connecting a pair of Front Height 
speakers, you will be able to enjoy surround sound in the 
vertical as well as horizontal direction.
• 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 thor-
oughly 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.
• Compressed Audio Restorer to enhance digital music 
files with portable music players
Connectivity & Future-ready Expandability
• 4 x HDMI in / 1 x HDMI out (Repeater)
The AVR-591 provides 4 HDMI inputs that let you simultaneously 
connect a variety of HDMI-equipped devices such as a game 
console and HD video camera as well as Blu-ray disc player.
•Dock connectivity for iPod and network streaming
Network music can be enjoyed via the Denon Networked Con-
trol Dock. (Requires optional ASD-51W or ASD-51N)
Ease-of-use
• On-Screen Display
With the AVR-591’s on-screen display, you can easily make 
settings for your home theatre system while viewing menus on 
the TV screen. You can check the status of each setting, such 
as the volume level when you’re adjusting the volume, or the 
name of the input source when switching input sources.
• 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 differ-
ent signal levels for each input device
• Variable subwoofer crossover switching
