Features & specs
High Power Custom Transistor: When temperatures rise or fall inside the unit, bias current values supplied to the power transistor tend to fluctuate, causing sound quality to deteriorate. The high power custom transistor used in the AVR-2803 ensures that the bias current is constantly uniform so that the sound you hear is of consistently stable, high quality.
Digital Surround Processing: The AVR-2803 features the new Analog Devices Melody 100 (Hammerhead SHARC) 32-bit floating point, high speed digital surround processor, operating entirely in the digital domain, to deliver accurate performance from digital sources such as DVD, LD, and DTV.
24-bit/96kHz All-channels Differential-mode D/A Conversion: For the optimum fidelity and transparency, the AVR-2803 features new high resolution Analog Devices 24-bit, 96 kHz DACs, in 16-DAC differential configuration (2 D/A channels per each audio channel).
Surround Modes: This receiver incorporates a wide variety of surround modes to bring you maximum enjoyment from your audio and video software. The surround modes include:
- Dolby Digital Surround EX (6.1)
- Dolby Digital (5.1)
- Dolby Pro Logic II (Music & Cinema)
- DTS-ES Discrete (6.1)
- DTS-ES Matrix (6.1)
- DTS (5.1)
- DTS Neo:6 (Cinema & Music)
- DTS-ES 96/24
- 5/7-Channel Stereo
- Rock Arena
- Jazz Club
- Mono Movie
- Video Game
DTS 96/24: The AVR-2803 can decode DVD-Video software recorded in DTS 96/24, which allows high-quality 24-bit, 96kHz audio playback in all channels with full-quality, full-motion video. High resolution 96/24 audio playback from ordinary DVD-Video recordings is limited to only two channels with some limitations on the picture.
Direct Mode: The Direct mode allows you to achieve good quality 2-channel sound while watching images. In this mode, audio signals bypass such circuits as the tone circuit and are transmitted directly.
5/7 Channel Stereo: Denon's popular 5/7 Channel Stereo mode transforms your favorite 2-channel sources such as CD, tape, stereo radio and stereo video sources into exciting surround sound, free of delay effects and unnatural artifacts, from all speakers.
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 II, Dolby Digital, DTS, and DTS Neo:6 surround modes.
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).
Variable Gain Volume Control: The receiver's volume control allows you to make fine adjustments of 0.5dB in an extended useable range of -80dB to +18dB. In addition, the signal-to-noise ratio in the useable area has been improved.
Dual Source/Dual Zone Capability: The AVR-2803 allows you to enjoy one program source in a second room while another source is playing in the main room. The Zone 2 output is a stereo pre-amp output that can send a signal to an amplifier or a set of powered speakers located in another room. The Zone 2 pre-amp output is variable, allowing you to separately adjust the volume with the receiver's remote. In addition, this receiver has a Power Amp Assign function, which allows you to assign the amplifier for the Surround Back channel to either the main room or Zone 2. There are two speaker outputs on this channel allowing you to power a pair of speakers in the main room (as Surround Back speakers) or in Zone 2.
Component Video Switching: In addition to composite and S-video switching, this receiver has two sets of component video inputs and one set of component video (monitor) outputs. Each of the component video inputs is assignable to different input sources. A high-performance relay is used to switch signals, and a high-frequency range of up to 100MHz is supported, giving it the ability to pass HDTV signals.
On-Screen Display (OSD): An OSD can be displayed on your television for easy system setup. The OSD can be displayed from the composite and S-video monitor outputs only.
7.1 Multi-Channel Inputs: The AVR-2803 is equipped with a 7.1-channel wideband (up to 100kHz) input to accommodate present and future multi-channel formats, such as DVD-Audio or SACD.
Selectable Crossover Setting: This receiver supports subwoofer crossover switching with a choice of 5 frequencies: 40, 60, 80, 100, and 120Hz. This lets you more accurately match the performance characteristics of the subwoofer to the main speaker system.
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.
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 A/V Learning Remote (RC-924): The AVR-2803 comes with a newly-developed infrared remote control with the most frequently used keys in the center. It is pre-programmed to control the receiver and other Denon A/V components. In addition, the remote is pre-coded for multiple brands of CD players and recorders, MiniDisc player/recorders, DBS Satellite receivers, VCRs, TVs, DVD players, Laserdisc players, cable boxes and cassette players. The remote can also "learn" the codes of other remotes if that component is not included in the Denon remote's library of preset memory codes.
Serial Control/Room-to-Room Ports: The AVR-2803 has a mini-jack input for a connection to an external remote control system, such as AMX or Crestron. The receiver also has a mini-jack input and output for Room-to-Room Remote Control. These jacks allow you to control other remote-controllable components with an optional Denon IR remote control extender system (RC-616, RC-617 or RC-618).
Surround Back/Zone 2 Speaker Outputs: This receiver is equipped with 7 discrete amplifiers, including two for the Surround Back/Zone 2 output. There are two speaker terminals (marked "L" and "R") sharing the Surround Back/Zone 2 amplifier. This allows you to connect two speakers in the main zone for the Surround Back channels, or power two speakers in Zone 2.
Note: The Power Amp Assign switch on the back of the receiver has to be switched to either "Surround Back" or "Zone 2", depending upon the zone being used.
Speaker Outputs: All speaker outputs have binding post connectors, allowing you to connect the speakers with bare wire, banana plugs or pin connectors. The binding posts are spaced too far apart to support dual banana plugs, and the collar surrounding each post prevents the use of spade lugs.
Digital Inputs/Outputs: This receiver has 6 assignable digital inputs and 1 digital output. There are 4 optical digital and 2 coaxial digital inputs. One of the optical digital inputs (Opt 4) is coupled with an optical digital output. Each digital input can be "assigned" to a different input source, or turned off if not in use.
Pre-out Jacks: This receiver has a total of 10 pre-out level RCA jacks for the following channels: Front left and right, Center, Subwoofer, Surround left and right, Surround Back/Zone 2 left and right, and Zone 2 left and right. These jacks allow you to connect the outputs to integrated amplifiers or powered speakers.
Headphone Jack: This unit has a gold-plated standard 1/4" headphone jack on the front panel. When headphones are plugged into the headphones jack, the speaker-level and pre-amp level outputs are automatically turned off.
12V Trigger Output: The AVR-2803 has a mini-jack output to send a 12-Volt DC "turn-on" signal to another component that accepts a 12V trigger, such as a power amplifier. The 12V trigger output can be assigned to as many source inputs as desired.
