Onkyo TX-RZ50

Potent home theater performance from Onyko

Modern-day home theater gear has opened the door to all sorts of wonderful A/V experiences. A powerful receiver like Onkyo's TX-RZ50 is an excellent example of why. It's equally skilled at delivering memorable movie nights, laid-back listening sessions, and high-octane gaming — all while offering intuitive, app-based control.

Ideal for a Dolby Atmos system

The nine-channel TX-RZ50 is ideal for powering a 5.1.4 Dolby Atmos or DTS:X™ system — that's the traditional five speakers and subwoofer configuration, plus two pairs of upward-firing or in-ceiling speakers for overhead sound effects.

Advanced video processing for movies and more

Onkyo equipped the TX-RZ50 with the latest video technology. All six of its rear-panel HDMI inputs support crisp 4K/120 video content — perfect for high-quality sources like a 4K Ultra HD Blu-ray player, an Apple TV, or your next-gen gaming system. (The front-panel HDMI input supports 4K/60 video content.)

Play music from a slew of sources

The TX-RZ50 lets you stream tunes from your phone or tablet via Bluetooth, Apple AirPlay 2, or Chromecast built-in. You can also play your collection of digital music files over your Wi-Fi network, or use the built-in phono input for your turntable. You can even play high-resolution tracks from a USB drive. 

Precise room calibration with Dirac Live® 

This receiver uses Dirac Live audio calibration — one of the industry's best room correction platforms. It measures the acoustics of your room with the included microphone, and then fine-tunes the output of your system to best match the unique sonic characteristics of your space.
