7.2-Channel Network A/V Receiver

The Onkyo TX-NR828 gives you - the avid music and movie fan - power to make your home entertainment dreams a reality.

Need music right now? With a tap on your smartphone screen you can serve lossless audio to your home theater - whether it's stored on handset, NAS, PC, or online streaming service - using built-in Wi-Fi, or pair up and stream with onboard Bluetooth technology.

Owning an Onkyo A/V receiver is not just about having big sound on movie night - it's about maximizing the enjoyment of your daily life.


Make Your Home Theater Dreams A Daily Reality

The TX-NR828 has built-in WiFi for app controlled network audio streaming, and built-in Bluetooth serves hi-res, lossless, and compressed audio files (including 192 kHz/24-bit FLAC, DSD, and Dolby® TrueHD) to your home theater from mobile devices, and it's all about stunning sound. Behind the brushed aluminum faceplate all seven channels have Three-Stage Inverted Darlington Circuitry, which effortlessly handles big dynamic gains without distorting, as THX Select2 Plus certification proves, and renders all audio in extraordinary detail.

Eight 4K-ready HDMI® inputs, and a frontside MHL (for mobile devices), decode dazzling audio and video. 7.2 multichannel pre-outs, powered Zone 2 outputs, and bi-amping capability make this a very flexible AVR. Audio is masterfully processed, and 4K video source signals are cleanly passed-through, and standard video can be upscaled to 4K. Two HDMI outputs (one with Audio Return Channel) are included to connect your TV or even a projector for an authentic big-screen experience.
