Treat yourself to powerful, pristine, and totally engrossing home theater with the Denon AVR-2809CI. This sophisticated receiver delivers 115 high-current watts to as many as seven speakers, enveloping you in detailed, lifelike sound. Denon also packed it with advanced features, like flexible digital video switching and upconversion, decoding for the latest surround sound formats, and versatile multi-room entertainment options.

Precision auto setup tailors sound to your room
For the most accurate home theater sound possible, Denon equipped this receiver with Audyssey MultEQ® XT, a sophisticated automatic speaker calibration system. The '2809CI uses the included microphone to analyze sound from up to eight different listening positions, then automatically adjusts level, equalization, and delay settings for each of your speakers. You get precise response across a wide listening area so everyone in the room can enjoy optimized home theater sound. Audyssey's Dynamic Volume mode keeps the sound clear and steady, eliminating those annoying spikes in volume that accompany commercials between TV shows.

Four HDMI inputs plus 1080p video upconversion
The '2809CI features 1080p-capable HDMI switching for four high-def video sources. Analog-to-HDMI conversion lets you send all your video sources to an HDMI-capable TV using a single digital cable, simplifying hookup and maximizing picture quality for each source. Plus, when you use the receiver's HDMI output, it can upconvert your non-HD video sources to resolutions as high as 1080p, for a better match with your HDTV's high-res display.

Multi-room flexibility and more
This receiver's three-room/three-source output lets you enjoy a surround sound movie in your main room while a housemate watches a different video source in a second room, and another housemate listens to stereo music in a third. A handy learning/multibrand touchscreen remote lets you easily control all of the components in your system. Denon's user-friendly, on-screen interface makes it a snap to operate the '2809CI using your TV screen.

Superior sound quality from every source
The '2809CI's heavy-duty construction includes an anti-resonant chassis, a massive power supply, and large capacitors for abundant reserve power to handle movie explosions and other sudden dynamic peaks. Denon's Dynamic Discrete Surround Circuit-HD provides dedicated circuit blocks for tasks like digital-to-analog conversion, analog-to-digital conversion, and surround decoding for optimal sound. Careful isolation of each block also ensures ultra-high signal purity. You'll enjoy powerfully precise home theater and music every time.
