The Official Denon AVR-2309CI Receiver Thread

<U>


The Denon AVR-2309CI will fill your room with detailed, enveloping surround sound. This future-ready receiver teams seven channels of high-current amplification with sophisticated digital processing to deliver a riveting home theater experience. You get decoding for the latest surround sound formats, including Dolby® TrueHD and DTS-HD™ Master Audio — two high-resolution surround sound formats available with many newer Blu-ray players and discs.
Four HDMI inputs plus 1080p video upconversion
The '2309CI features 1080p 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 upgrade your non-HD video sources to resolutions as high as 1080p, for a better match with your HDTV's high-res display.
Precision auto setup tailors sound to your room
For the most accurate home theater sound possible, Denon equipped this receiver with Audyssey MultEQ®, a sophisticated automatic speaker calibration system. The '2309CI uses the included microphone to analyze sound from up to six 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 instead of just a single "sweet spot," so everyone in the room can enjoy optimized home theater sound.
Superior sound quality from every source
Beefy Denon construction includes twin independent power transformers plus six independent power supply circuits to ensure your music and movie sound always comes through strong and clear, even during heavy dynamic peaks. Pure Direct mode shuts down all unneeded circuitry and the front-panel display to eliminate any potential interference, giving you the cleanest possible audio.
