A strong audio and video performer
If you're a music lover, sound quality may well be your top priority in a receiver. But that doesn't mean you're willing to sacrifice picture quality when it comes to movies and TV. Fortunately, the Denon AVR-X2100W IN-Command receiver requires no such sacrifice. This is a video-lover's receiver, with features to help you get the most out of all your video sources. Advanced video processing can upconvert standard-definition analog signals to HDMI in 1080p or 4K for use with HD and Ultra HD TVs. There are component video connections to bring older gear into the fold. There's also a second HDMI output for large home theaters with multiple displays such as a projector and TV. Of course, the 'X2100W also sounds wonderful, feeding your speakers plenty of power and decoding all the latest high-resolution audio formats to please critical listeners and impress anyone with a set of ears.
Wireless versatility for all your digital tunes
With all the various devices we use to play music, the hardest part can be playing them all through our home theater speakers. The AVR-X2100W takes all the mystery out of this process. Have a networked computer or music server? Built-in Wi-Fi along with DLNA compatibility will place your entire collection at your fingertips. Have a tablet and smartphone? If it's an Apple® device, AirPlay has you covered. If it's Android™ or another platform, built-in Bluetooth will do the trick. Are you a subscriber to Spotify's premium service? Access their entire library through the Spotify app and play it all back with this receiver. Plus, there's Pandora, SiriusXM, and free Internet radio streams all accessible using this receiver on its own.
The free Denon Remote App turns your Apple or Android smartphone into a powerful Wi-Fi remote.
Wish you could have music playing in two rooms? The 'X2100W can help you do it. Its multi-zone feature means it can power speakers in two rooms simultaneously — playing different songs in each or the same song in both rooms. Use the surround back speaker outputs to power stereo speakers in another room. Connect them in a kitchen, bedroom, or out on a porch to listen to tunes while the rest of the family enjoys a movie in 5.2-channel surround sound in the home theater.
Sound that's tailored to your room
To get sound that's perfectly optimized for your room and speaker setup, you'll need to calibrate your speakers. Luckily, that's as easy as plugging the included microphone into the AVR-X2100W's front panel and pressing "Start." The mic will take speaker measurements as test tones are played. Then, the receiver's Audyssey processing will adjust settings to guarantee well-balanced surround sound in your room. Audyssey's Dynamic EQ and Volume features help your system perform better at lower volume levels and minimize large volume fluctuations while watching TV or movies.
Control it with your smartphone or tablet
Denon's free Remote App can turn your smartphone or tablet into a powerful Wi-Fi remote control. Download it on your Apple or Android device and use it to change sources, adjust the volume, control music in multiple zones, and listen to Internet and network music sources.
Home automation capabilities
Like all of Denon's IN-Command receivers, the AVR-X2100W offers useful home automation features. It can be set up and operated by a computer over a wired or wireless home network via IP control. There's an infrared input on the rear-panel, for use with external remotes and control systems. And the AVR-X2100W is certified for use with Control4 home automation equipment.
