Features

7-Channel Equal Power Amplifier: The Denon AVR-2808CI features a 7-channel equal power, discrete amplifier. The amplifier is rated at 110 watts x 7-channels RMS.

AL24 Processing Plus: Denon has further developed its propriety AL24 Processing to support the 192 kHz sampling frequency of DVD-Audio. AL24 Processing Plus thoroughly suppresses quantization noise associated with D/A conversion of LPCM signals to reproduce the low-level signals with optimum clarity that will bring out all the nuances of the music. AL24 Processing Plus is applied to not only the front left and right channels, but also the surround left and right, center and subwoofer channels.

24-Bit, 192 kHz D/A Converters: The AVR-2808CI uses 24-bit/192-kHz Digital-to-Analog converters for all channels. The 192kHz sampling and 24-bit word length capabilities of the DACs allows you to play high-resolution recordings and hear the increased clarity, detail and dynamic range of those recordings.

DDSC HD-Digital (Dynamic Discrete Surround Circuit): The Denon AVR-2808CI is equipped with the latest technology in surround audio performance, DDSC HD-Digital, featuring dual Analog Devices Hammerhead SHARC 32-bit floating point DSP processors. All elements of the Surround Processor are optimized to the highest standards by the use of selected high performance and discrete components, particularly the A/D and D/A converters and the sophisticated DSP surround decoder.

Custom Integration: The AVR-2808CI carries the "CI" stamp, which is Denon's certification to custom installers that the receiver has advanced connectivity and control features often required for custom home integration and theater applications using premium control systems. These features include a RS232C jack for use with whole house control systems, remote in/out IR command control, and assignable +12-volt triggers.

Video Up-Conversion Powered With DCDi By Faroudja: The AVR-2808CI is equipped with a flexible video switching system that converts video signals in an effort to only require one video connection from the receiver to your TV. The video switching system features a Directional Correlation De-interlacing (DCDi) special video processor developed by Faroudja that involves advanced algorithms to remove the jagged edges that appear when standard interlaced video is viewed on progressive scan displays. DCDi converts standard interlaced signals into progressive scan signals in order to eliminate the stair-casing effect that conventional up-converters can introduce to diagonal edges. Unlike most other conversion circuits, this receiver will convert analog signals from composite video, S-Video, and component video to HDMI up to 1080p.

Noise Shaped Video (NSV): The NSV precision video feature works in the digital domain to reduce noise in the video signal frequency band in order to enhance video signal linearity, provide accurate signal representations, and enhance the picture quality. Noise shaping techniques can be combined with dynamic element matching techniques in order to reduce the matching requirements of DAC elements by converting the analog mismatch into  and out of band noise. This approach of dynamic element matching and noise shaping has been shown to allow the use of sigma delta modulation at video data rates. NSV can achieve ultimate precision with 12-bit fidelity in both digital-to-analog and analog-to-digital domains.

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:

Surround Parameters: You can adjust the following surround mode parameters:

Tone Settings: You can independently adjust the system's overall Bass and Treble settings from -6 to +6 dB. These settings can be set for the main zones, as well as zones 2 and 3.

Night Mode: This mode is optimized for late night listening. You can select from the following Night Modes - Low, Middle, High or Off.

Restorer: This function restores compressed audio signal to how they were before compression and corrects the sense of volume of the bass to obtain richer playback sound. You can select from one of the following modes - Mode 1, Mode 2, Mode 3 or Off.

Two-channel Music Modes: There are three 2-channel playback modes exclusively for music:

Personal Memory Plus: The receiver has a personal memorize function that automatically memorizes the surround modes and input modes selected for the different input sources. When the input source is switched, the modes set for that source last time it was used are automatically recalled. The surround parameters, tone control settings, and playback level balance for the different output channels are memorized for each surround mode.

Auto Setup: The receiver is equipped with an Auto Setup and Room Equalization function, to achieve the most ideal sound field for your room. The AVR-2808CI's Audyssey MultiEQ XT function is designed to optimize the sound quality at each listening position in the room. The included DM-A405 microphone is used to measure test tones at each listening position. This measured data is then analyzed using a program to improve acoustic characteristics in the listening area. For best results at least 8 positions should be measured, including a main position. The main position is given more weight in the calculations. The Audyssey function adjusts the following measurements automatically: Speaker Configuration, Distance, Channel Level, Crossover Frequency, and Room EQ.

Room EQ: The Room EQ function offers the following adjustments:

Subwoofer Control: You can adjust the cutoff frequency of the subwoofer output from 40Hz, 60Hz, 80Hz, 90Hz, 100Hz, 110Hz, 120Hz, 150Hz, 200Hz or 250Hz. You can also select the subwoofer output level between 0, 5, 10 or 15 dB.

Amplifier Assign: There are seven amplifier channels built into the receiver. These channels are typically used for 7.1 channel surround in the main room, but the amplifier assign function gives you the option of configuring the system differently if you prefer. The amplifier features four different amplifier assignment configurations.

Bi-Amp: Four of the seven amplifier channels can be used to bi-amp the front speakers, leaving three to power other channels.

Multi Zone/Multi Source Operation: Denon's Multi-Zone/Multi-Source function lets you select different audio/video sources for listening and viewing in different locations of your home. The AVR-2808CI features a Main Zone (Zone 1), Audio/Video Zone (Zone 2) and Audio Only Zone (Zone 3). The Main Zone 1 contains 7.1-channel playback of your audio/video gear in your main entertainment room. The Audio/Video Zone 2 allows stereo audio and video playback of another AV source connected to the receiver in another room of your home via left/right RCA audio or speaker terminal output connections and a composite video connector. Audio Only Zone 3 allows you to play a stereo audio source connected to the receiver in a 3rd room of your house via left/right RCA audio or speaker terminal output connections.

iPod Compatibility: Using the optional Denon ASD-1R iPod dock (033ASD1RBK or 033ASD1RWT), you can connect your iPod to the AVR-2808CI. Folder and file names appear on the receiver's display panel.
