Denon AVR-1910 7.1-Channel A/V Home Theater Multi-Source/Multi-Zone Receiver(DENAVR1910) and other affordable Audio Receivers at 6ave.com.

The Denon AVR-1910 receiver is a powerful receiver delivers 90 high-current watts to as many as seven home theater speakers, enveloping you in realistic, lifelike sound. You get decoding for the latest high-resolution surround sound formats, including Dolby® TrueHD and DTS-HD™ Master Audio, plus the very latest Dolby technology -- Dolby® Pro Logic® IIz. This cool new processing lets you add optional pair of front "height" speakers as an alternative to using two surround back speakers. You can place these above your main front speakers to enjoy a larger soundstage with an expanded vertical dimension -- an excellent sonic enhancement to video games and movies.

1080p HDMI switching
The '1910 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. When you use the receiver's HDMI output, it can up-convert your non-HD video sources to resolutions as high as 1080p, for a better match with your HDTV's high-res screen.

MultEQ® auto-calibration
Denon includes sophisticated MultEQ® auto-calibration to take the guesswork out of setting up your surround sound system. Using the supplied microphone, MultEQ analyzes sound from up to six different listening positions in your room, then automatically adjusts level, equalization, and delay settings for each speaker.

Dual-room/dual-source audio capability
Dual-room/dual-source audio capability lets you enjoy home theater in your main room while a housemate enjoys stereo music in a second room. You can integrate your iPod® by adding one of Denon's control docks, and tune in to SIRIUS Satellite radio with the addition of an optional Sirius Connect™ home tuner kit.
