Product Description

Product Description

The new AVR-791 is packed with technology and features making it the clear choice for value oriented consumers looking for exceptional performance. Each of its 7-amplifier channels produce 90-watts of power, delivering detail and dynamics to music and movie soundtracks. They can be configured for 7.1 channel surround sound, or drive a 5.1 channel system in the main room and power a pair of speakers in a second “zone”. It’s equipped with 1080p and 3D (all formats) compatible HDMI 1.4a Repeating technology, delivering both audio and video to your HDTV with single HDMI cable. This HDMI connectivity supports the latest generation surround sound formats available on Blu-ray disc, including Dolby TrueHD and DD+, dts-HD and dts-HR. Also included is Dolby Laboratories new Pro Logic IIz Matrix decoding featuring front height effects channels that expands front soundstage. The AVR-791 boasts a number of Audyssey technologies. Advanced Audyssey MultEQ analyzes a speaker systems interaction with room acoustics, and then delivers custom tailored correction processing to optimize clarity and tonal balance throughout the listening space. Audyssey Dynamic Volume is an automatic volume-leveling system that tracks audio dynamics to eliminate the irritating volume swings between TV shows and commercials. Audyssey Dynamic EQ is also on board to ensure rich bass and smooth tonal balance at low volume listening levels. In addition to enhanced HDMI 1.4a repeating (4 in, 1 out), the AVR-791 is the least expensive receiver in the Denon lineup to feature 1080p i/p conversion, analog to HDMI upscaling and HDMI to HDMI scaling. Video conversion is accomplished using a premium Anchor Bay Technologies chip set featuring 10-bit processing. The AVR-791 also features 2 component video inputs, seven analog inputs, and multi-zone / multi-source capability. A front-panel USB input allows quick and easy connection for iPod/iPhone, Flash Drives and HDD with command and control functionality.

Equipped with 4 HDMI inputs, the AVR-791 includes the latest HDMI 1.4a specification, which provides 3D pass-through (Broadcast and Blu-ray) capability, as well as providing Audio Return Channel.

Audio Return Channel

With Audio Return Channel (ARC), you can play back the TV audio in surround sound with a single HDMI cable. Until now, if you wanted to enjoy surround sound from a TV, you needed to use an optical digital or coaxial digital cable to bring sound from the TV to the AV receiver. The AVR-1611's ARC feature helps you keep cable connections neat and out of the way as you build your home theater.

High Resolution Surround Sound

For the ultimate surround sound experience, the AVR-791 features the latest high resolution audio decoders, including Dolby TrueHD and DTS-HD Master Audio, formats found on Blu-ray discs. The AVR-791 is also equipped with Dolby Pro Logic IIz, which provides the option of front height effects channels, for a dramatic front soundstage, with Movie, Music and Game modes, breathes new life into your favorite stereo sources.

Quality Discrete Power Amplifier Section

The equal power amp design features 7 discrete power amp circuits, and each channel is rated at 90 watts (8 ohms, 20 Hz to 20 kHz, .08% THD). 2 of the amp channels can be configured for surround back, or front height effects, or they can be assigned for stereo multi-room use.

Easy Setup With Automatic Room Acoustic Correction

Audyssey MultEQ dynamic room acoustic correction system features a microphone (included) to automatically measure the speaker configuration and provide acoustic tailoring for the best surround sound experience. Dynamic Volume helps eliminate jarring volume jumps during commercials, and Dynamic EQ provides a rich tonal balance at any volume level.

Ergonomic Design Promotes Easy Control

With its programmable functions and intuitive button layout, the AVR-791 is designed to maximize ease of use. The front panel is smartly organized, featuring clearly-labeled buttons and onboard controls for volume and source. The AVR-791's remote can sync with other entertainment devices in your home theater, eliminating the need for additional remote controls. It can also be easily programmed with macro functions, giving you more flexibility in controlling your home theater.

Dock Connectivity for iPod and Network Streaming

Network music can be enjoyed via the optional Denon Networked Control Dock.

7-Channel Equal Power

7-Channel Equal Power is a feature used in various Denon amplifiers to connect 7 speakers independently so that separate power amps connected via pre-outs are not required. It allows you to connect the second 'surround back' speaker to complement the surround back speaker for 6.1, straight off the main amplifier without adding a power amplifier to support 7.1 surround formats. Amplifiers with 7-Channel Equal Power have built-in separate internal amplifiers to power each channel independently, thus allowing you to enjoy the same high power output capability per channel, giving a balanced and truly high-impact surround-sound environment.

7-Channel Stereo

Denon's 7-Channel Stereo mode enables top quality normal two channel stereo output from the surround speakers to provide a unique 7 channel stereo option. This mode can be fully utilized from any high quality stereo source via CD, tape, FM-radio or video recorder for dynamic 7-channel output. The 7-channel stereo is available if you have a surround back right speaker connected as well as the surround back left speaker used in 6.1, otherwise you can still experience multi-channel stereo output using a 5-channel-stereo or 6-channel-stereo configuration.

There are three $500 receivers to consider, if you're buying one in 2010 - Onkyo TX-SR608, Pioneer VSX-1020-K and this one. All three feature the latest HDMI 1.4, which is necessary for 3D signals. Here's how they compare:

-The Onkyo is the most powerful in terms of real world performance, followed by the Denon and finally the Pioneer. All three perform at par for normal listening volumes, but the Onkyo can handle very high volumes the best, while the Pioneer runs out of breath

-The Denon has Audyssey Multi-Eq, which automatically calibrates the receiver for use in your room (a mic is provided). The Onkyo has a similar but less versatile Audyssey 2EQ. Pioneer has its own system called MCACC which also works well, but Audyssey may be slightly better.

-All three can upconvert analog sources via HDMI - hence you'll only need one HDMI cable to connect to the TV. The 1.4 spec supports an audio return channel, so the TV's sound can be output to the receiver without extra cables. The Pioneer and Denon use the excellent Anchor Bay chipset, while the Onkyo uses the slightly inferior Faroudja DCDi chipset for video processing.

-The Pioneer and the Denon have a front USB input where you can connect your iPod directly. You can browse playlists etc using the receiver's remote via the onscreen display. Since this is a digital connection, the sound quality is excellent - while the iPod can be connected to the Onkyo via an analog cable, it does not sound as good and cannot be navigated using the remote.

This works much better than my old Yamaha RX-V661 receiver. The key features I liked were:

* Audyssey Dynamic Volume for automatically turning the volume down for commercials and up for quiet scenes so that you don't have to keep your finger on the remote when trying to keep the TV commercial volume below a certain level. This is a key selling point in my opinion! You can configure it to 4 settings depending on how dynamic you want it. Just like the Starbucks style of sizing, instead of small, medium and large, you have Off, Day, Evening and Night in the menu. Day compensates the volume the least, and the Night compensates the volume the most. The Evening setting seems fine to me.
* When you first configure it, it configures the sound levels specific to your room configuration for up to 6 listening points with an included microphone. It detects the frequency cross over for your speakers and speaker specific volume levels for optimal listening. It can also detect miswired speakers.
* 4 HDMI input ports and 1 HDMI output port.
* iPod USB connection. You can use the remote to control the song selection.
* Delete unused inputs for easily skipping over unused inputs.
* Analog video conversion to HDMI. This is good for playing the Wii or other older cable inputs without switching TV inputs.
* It doesn't have an excess abundance of inputs. So it's a little easier to wire up.
* You can rename the inputs to make it easier for everyone in the family to remember.
* You can configure which inputs are used for each video/sound combination. This is probably why there are fewer inputs. For simple configurations, the defaults will be good enough.
* If you don't like the default brightness on the display, you can turn it down in the menu.

The audio and video performance of the Denon AVR-791 is exceptionally good. The amp has plenty of power, good audio processing features, a very clean sound, and a good balance of audio and video input/output formats (I really need one more component analog input, and I'd like one more S-Video input, but didn't want to spend the $$ for the upgrade to the AVR-891). There were two specific features that were a "must have" for me: upsampling of analog inputs to HDMI 1080P, and compatibility with the newest 3D signal formats (to go with my new Samsung 3D Blu-Ray player and TV). The video upsampling is top notch - running a standard def DVD from my old Pioneer player (using the upsampling in the Denon) looks better than playing the same DVD back in my new Samsung Blu-Ray player (using the Blu-Ray's upsampling to 1080P). I did the tests using standard off the shelf movies, as well as the "Microsoft Hardware Compatibility Labs" DVD Test Disk.

The Audyssey auto setup works remarkably well and gets all the audio settings "close enough". I was able to get it to sound a little better with a little fine tuning, but most people should be happy with the auto setup (I am using the Definitive Technologies ProCinema 600 speakers, which are a great match for this amp).

My biggest complaint is with the on-screen menus and the remote control. The on-screen menus are horrible, with standard definition black/white text that looks incredibly ugly in 1080P. The menu navigation in general seems like it was bodged together without much thought. The remote control has the opposite problem - it is so over-engineered and it has so many buttons and shift functions that it is impossible to figure out.
