Onkyo TX-NR646 7.2-Channel Network A/V Receiver

Connect this A/V receiver to your television and speaker system to enjoy high-quality video and audio from cable boxes, media players, and video-game consoles.

Hear the Action Unfolding Around You

Feel like you’re in the theater when watching your favorite movie, or in the broadcast booth when watching your favorite team. 7.2-channel surround sound stages immersive, cinematic audio by placing seven total speakers in front of, beside, and behind you, creating a near-360° soundscape that lets you pinpoint details as precise as a twig snapping in the forest, or a referee whistling from the sideline. Two subwoofers heightens this realism with rich low frequencies, doing everything from intensifying explosions to making hushed dialogue easier to understand.

Authentic Sound Reproduction

Hear the shushed whispers in a quiet drama or relish the crystal-clear licks of an impeccably recorded rock anthem. Thanks to the receiver’s high-current amp, audio remains dynamic and accurate to its source.

Watch Videos in Unparalleled Detail

The receiver’s eight HDMI ports eagerly await connections from media players and video-game consoles with 4K Ultra HD and 3D capabilities. After plugging in devices, the receiver transmits the signal to your HDTV and presents video in stunning clarity and detail.

Bluetooth and WiFi: Stream Wireless Music, Internet Radio, and Podcasts

Bluetooth and WiFi let you stream wireless music from an enabled mobile device, leaving you free to mingle with guests, clean the house, or do yoga—all without interrupting the music. Moreover, the wireless connections play your favorite songs over the system’s speakers, filling the room with richer sound than most smartphones, tablets, or laptops can.

It's not a bad unit but Wi-Fi disconnects and won't connect back unless the receiver is power cycled.

Enjoying my new purchase Onkyo TX NR646. Just started upgrading my very dated sound system (purchased in the early 90's). It has become clear I will need to add a subwoofer to round out my sound (Klipsch Icon speakers) , as I am sure I will be using the receiver for rocking out more than surround sound for movies. \n\nNewly converted Female Audiophile.

For several months I'd been searching for a receiver that meet a very specific requirements list... It had to have at least 5 channels plus a subwoofer, network connectivity, and then the thing that was killing me, a phono input. I was also limiting the search to quality brands - Denon, Yamaha or Onkyo. And, I wanted all this to come in under $400. When this receiver showed up in my email I was shocked - could such a holy grail exist? After checking reviews on other sites, I couldn't place my order fast enough. It finally arrived, and absolutely did not disappoint. Spectacular sound, everything works as I needed it to, I am beyond satisfied with this purchase!

This Receiver is better then I was expecting. All the features that is says it has work flawlessly. This is replacing my Sony Receiver that only lasted 4 years and it blows it out of the water.\nWould recommend to anyone go ahead and buy this one.
