Our take on the Denon AVR-4802R by Crutchfield's Barry Montgomery
The AVR-4802R's THX® Ultra2 certification is your guarantee of phenomenal home theater performance. This receiver meets Lucasfilm Ltd.'s most rigorous standards for 7.1 processing savvy, power reserves, and sonic purity. It's also got exclusive Ultra2 processing enhancements that make the best possible use of your entire 7.1 speaker system with the full spectrum of home theater and music sources.
With on-board decoding for THX Surround EX, Dolby® Digital EX, DTS-ES®, and DTS 96/24, the AVR-4802R can handle virtually any home theater source you throw its way. And Denon's Widescreen 7.1 mode lets you turn any surround source into thrilling 7.1 audio. Another high-end home theater feature is the Audio Delay control, which lets you correct the lip-synching problems that crop up occasionally on digital video sources like DVDs and HDTV broadcasts. Dual 32-bit SHARC processors provide pristine execution of all this high-end digital processing.
125 full-bandwidth-rated watts x 7 channels of ultra-clean Denon power maximizes the dynamics and impact of every source. Back-panel highlights include 3 component video inputs, 8 digital inputs, 8 A/V inputs, and an RS-232C port for future upgradability. And the AVR-4802R's dual-room/dual-source capability lets you and a housemate each enjoy a different source in two different areas of your home simultaneously!
For the cleanest possible stereo sound, Pure Direct mode shuts off power to the video circuitry and front-panel display. With analog sources, Pure Direct also shuts off the digital circuitry. In addition, the AVR-4802R offers Denon's renowned AL 24 (ALPHA 24) processing, which uses sophisticated interpolation to produce analog smoothness from stereo digital audio.
An on-screen menu lets you view command menus on your TV for especially easy navigation. The learning/multibrand remote can control all your A/V components, and its programmable macros let you execute a series of system commands with the touch of a single button. A one-line LCD window on the remote shows you which component you're currently controlling, and all keys are illuminated for easy use in the dark.Details:

Features and Specs
Home THX Cinema Surround: THX is an exclusive set of standards and technologies established by the world-renowned film production company, Lucasfilm, Ltd. The intent is to make the experience of the film's soundtrack, in both movie theaters and in home theaters, as faithful as possible to what the director intended. Home THX Cinema Surround incorporates patented technologies to accurately translate the sound from the movie theater environment into the home, correcting the tonal and spatial errors that occur. These technologies include:
- Re-Equalization: The tonal balance of a film soundtrack will be excessively bright and harsh when played back over audio equipment in the home because film soundtracks are designed to be played back in large movie theaters using very different professional equipment. Re-Equalization restores the correct tonal balance for watching a movie soundtrack in a small home environment.
- Timbre Matching: The human ear changes our perception of a sound depending on the direction from which the sound is coming. In a movie theater, there is an array of surround speakers so that the surround information is all around you. In a home theater, only two speakers located to the side of your head are used. The Timbre Matching feature filters the information going to the surround speakers so that they more closely match the tonal characteristics of the sound coming from the front speakers. This ensures seamless panning between the front and surround speakers.
- Adaptive Decorrelation: In a movie theater, a large number of surround speakers help create an enveloping surround sound experience, while in a home theater there are usually only two speakers. This can make the surround speakers sound like headphones that lack spaciousness. The surround sounds will also collapse into the closest speaker as you move away from the middle seating position. Adaptive Decorrelation slightly changes one surround channel's time and phase relationship with respect to the other surround channel. This expands the listening position and creates, with only two speakers, the same spacious surround experience as in a movie theater.
THX Ultra 2 Certification: The AVR-4802R satisfies the strict standards of Lucasfilm, Ltd. governing performance, features, sound quality, power, stability into low-impedance speaker loads (3.2 ohms and higher), and ease of operation.

Pure Direct Mode: In addition to surround sound playback, the AVR-4802R lets you enjoy pure 2-channel stereo sound as well through its Pure Direct mode. In Pure Direct Mode, while listening to digital sources, power to the video circuitry and the front panel display is turned off, and with analog source inputs, power to the digital circuitry is also automatically turned off.
Audio Delay: The Audio Delay function corrects for slight lags between the sound and picture (Lip Synch) that can occur when a video signal is processed, such as in a Progressive Scan DVD Player or outboard video processor.
High-Quality Pure Audio Chassis Construction: Unwanted vibration is minimized by placing the power transformer near the center of the unit, the digital circuitry beneath the center, and the power amp circuits on the left and right sides. By also separating the analog circuit and video circuit sections, mutual interference among all the circuits is eliminated. This chassis design is well suited to the faithful reproduction of all types of sources, from the delicate purity of 2-channel stereo music recordings to the high-quality multi-channel soundtracks of DVD-Audio and the dynamic realism of sound and picture signals from DVD-Video programs.
Wide Range Circuit Topology: Front end and power amplifier circuitry is designed with flat frequency response that extends to 100 kHz, perfectly suited for wide-range audio media such as SACD and DVD-Audio.
24-bit, 96 kHz A/D Converters: The AVR-4802R uses highly accurate 24-bit, 96 kHz A/D converters to handle analog to digital conversion. Since the converted digital signals are at extremely high resolution, the resulting sound quality is far more faithful to the original source than with conventional designs.
ALPHA 24 Processing: The AVR-4802R includes Denon's renowned 24-bit ALPHA processing technology that reproduces digital signals in a waveform with the smoothness of analog signals. This technology thoroughly suppresses annoying quantization distortion and faithfully reproduces the delicate musical details of low-level signals. ALPHA 24 processing works in 2-channel Stereo, Direct, Pure Direct modes.
DDSC-Digital (Dynamic Discrete Surround Circuit): DDSC-Digital is a circuit configuration specially designed by Denon in which all the elements of the surround processor are optimized by the use of selected high performance discrete elements, including separate A/D and D/A conversion, with sophisticated dual DSP surround decoding.
Dual 32-bit SHARC Processors: Featuring the latest Analog Devices 32-bit floating point SHARC DSP devices, the AVR-4802R provides superb resolution and widest dynamic range of Dolby Digital, DTS and PCM audio signals.
On-Screen Display (OSD): An OSD can be displayed on your television for easy system setup. The OSD is sent through the Monitor 1 S-video and composite video monitor outputs; the OSD is not sent through the component video output, the Monitor 2 S-video output or the Monitor 2 composite video monitor output.
Multi-Zone Output: With the AVR-4802R's Multi Zone Output and Select functions, you can output different program sources to multiple zones. Sources can be selected for output to one additional zone besides the main room (or home theater). This zone, Multiroom Zone 1, can utilize a pair of variable preamp output jacks for connecting an optional amplifier to drive the speakers in that zone. Since the outputs are variable, you can control the volume with the receiver's remote control (separate remote control repeater system required). The AVR-4802R's Power Amplifier Assign function also lets you assign the 2 Surround Back amplifier channels to drive two speakers in Multiroom Zone 1 with 125 watts per channel, while still providing full 5.1-channel output to the main room.
Dual Surround Speaker Mode: The AVR-4802R provides the ability to connect two different sets of surround speakers, and place them in the appropriate locations in your home theater room, so that you can enjoy both movie soundtracks and music listening, with optimum results and no compromise.
Personal Memory Plus: The Personal Memory Plus function automatically memorizes the surround modes and input modes selected for the different input sources. When an input source is selected, the modes stored in memory for that source are automatically recalled. The surround parameters, tone control settings and playback level balance for the different output channels are memorized for each surround mode.
Bass Management and Speaker Setup: Various speaker size settings are available to ensure that small speakers do not receive full-range signals and to tell the receiver where to send signals. A test tone can by played through each speaker, allowing you to independently adjust the level of each channel. In addition, you can set a delay time for each channel, adjustable from 0-60 feet in 1-foot increments.
CINEMA EQ. (Cinema Equalizer): The Cinema EQ function gently decreases the level of the extreme high frequencies, compensating for overly-bright sounding motion picture soundtracks. Select this function if the sound from the front speakers is too bright. This function only works in the Dolby Pro Logic, Dolby Digital, DTS Surround and Wide Screen modes.
D.COMP. (Dynamic Range Compression): Motion picture soundtracks have tremendous dynamic range (the contrast between very soft and very loud sounds). For listening late at night, or whenever the maximum sound level is lower than usual, the Dynamic Range Compression allows you to hear all of the sounds in the soundtrack (but with reduced dynamic range). This only works when playing program sources recorded in Dolby Digital or DTS. You can select one of the four settings: "OFF", "LOW", "MID" (middle), or "HI" (high).
Dialogue Normalization: The dialogue normalization function is activated automatically when playing Dolby Digital program sources. Dialogue normalization is a basic function of Dolby Digital, which automatically normalizes the dialog level (standard level) of the signals that are recorded at different levels for different program sources, such as DVD, DTV and other future formats that will use Dolby Digital.
On-Screen Display: This unit has an on-screen display to assist you in the setup and use of the receiver. The OSD is output from the Composite Monitor 1 and/or the S-Video Monitor 1 outputs, depending upon the video signals being input to the receiver. They are not output from the component video outputs, or the Composite Monitor 2 or S-Video Monitor 2 outputs.
Last Function Memory: This unit is equipped with a last function memory, which stores the input and output setting conditions as they were immediately before the power was switched off.
Back-Up Memory: The unit is also equipped with a back-up memory. This function provides approximately one week of memory storage when the main unit's power switch is off and with the power cord disconnected.
Multibrand/Learning Remote: The AVR-4802R comes with the RC-932 Multibrand A/V Wireless remote control. In addition to being pre-programmed to control many brands of audio/video source components and TVs, this remote also has learning capability, allowing it to be customized for any installation. Dimensions: L=9.042", W=2.25", H=1.448".
System Call: Up to 10 sequential commands can be stored in each of two System Call (Macro) functions.
Variable Backlight Time: The RC-932 remote's backlighting time can be set between 3 and 30 seconds.
Assignable Digital Inputs: You can assign a component to each of the five optical and three coaxial digital inputs. The components you can select from include: CD, DVD, VDP, TV, DBS/SAT, VCR-1, VCR-2, VCR-3, TAPE, or V-AUX.
Optical Digital Outputs: Optical Digital Inputs 4 and 5 have corresponding optical digital outputs. These outputs allow you to send 2-channel digital signals to other components, such as CD or MiniDisc recorders or DAT decks.
Video Switching: This unit has 8 video inputs, 3 video outputs (VCR 1, 2 and 3), and two monitor outputs, all with composite and S-Video jacks. There is no video conversion, so each video source has to be output the same way as it was input. The unit's on-screen display is output through the Monitor 1 jacks only.
Component Video Switching: In addition to composite and S-Video switching, this unit can switch between three high-resolution, component video sources. There are 3 component video inputs and 1 component video output, each with gold-plated jacks labeled "Y", "PB/CB" and "PR/CR". The bandwidth of the component video inputs/outputs is 50 MHz, capable of passing through wideband (480p, 720p, 1080i) video signals for DTV and Progressive Scan DVD players.
Speaker Terminals: All of the receiver's speaker terminals are binding posts. They are not 5-way binding posts because a plastic collar prevents their use with spade lugs and they are positioned too far apart to be used with dual banana plugs.
Preamp Outputs: This receiver offers 7.1-channel preamp outputs, allowing you to connect separate amplifiers if desired. There is also a stereo preamp output for Multiroom Zone 1.
7.1 Multi-Channel Input: The AVR-4802R is equipped with a 7.1-channel input to accommodate present and future multi-channel formats, such as DVD-Audio and SACD.
RS-232C Port: The receiver has an RS-232C port on the rear panel to accommodate an external remote controller.
Room-to-Room Remote Jacks: The receiver has a mini-jack input for an external remote controller. The adjacent room-to-room output is for future use.
Power Amp Output: The receiver provides a 12-volt DC trigger to turn on/off a compatible external amplifier used to power speakers in Multiroom Zone 1.
