AVR-2800
Dolby Digital and DTS A/V Receiver
Outstanding surround sound an affordable price, with Dolby Digital and DTS decoding.
Featuring the latest in Dolby Digital and DTS decoding technology, the AVR-2800 provides outstanding home theater surround
sound performance. The heart of the AVR-2800 is Denon's Dynamic Discrete Surround Circuit-Digital technology, incorporating
high performance dual DSP chips and superior A/D and D/A conversion devices. This provides superb listening results, with virtually any
home theater or music source. Prepared for the future, the AVR-2800 features 6-Channel external input, for connection to future
multi-channel surround formats. A high quality, discrete power output section provides a total system power of 425 watts RMS into
8 ohms. Full 24 bit, 96 kHz digital-to-analog D/A converters on all 6 channels (3 stereo pairs) provide transparent reproduction of
multi-channel music and motion picture soundtracks with outstanding dynamic range and superb low level resolution. Outstanding
surround sound an affordable price, with Dolby Digital and DTS decoding. The AVR-2800's remote controller features an easy-to-
use layout where most frequently used buttons are provided in different colors and shapes for easy recognition, even while keeping
your eyes on the screen. The buttons also feature "Self-illuminated GLO-KEY" for easy operation in the dark.

is due in part to the high-grade signal processing of the 24-bit,
96-kHz Digital Interface Receiver (DIR). The AVR-2800 not only
allows digital signals input from DVD and other advanced media
to pass directly to the DIR, it also processes them while preserv-
ing their integrity so that even the most delicate nuances of the
music, reflecting the emotions of the artists, are passed unfet-
tered to the dual digital signal processors (DSP).
