  • Product Description

    The TX-RZ50 delivers enormous power on-demand to highlight every nuance of the music, movies, and games you love.

    Potent home theater performance from Onkyo

    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.

    Product Features

    Ultimate 4k Gaming Experience

    4K/120 enables ultra-fast motion UHD images to be crisp and razor-sharp; and sports, action movies, and high-performance gaming benefit significantly. The TX-RZ50 supports higher performance from streaming devices like the latest Apple TV.

    Discrete Zone 2 HDMI Swithcing

    Set up different Ultra High-Definition entertainment options with up to 8K60 resolution* in two different rooms from your Onkyo receiver. Watch a movie in the home theater, while the kids watch cartoons in their playroom.*

    *8K60 only valid for Zone 1/Zone 2 will only produce 4K120 resolution when two separate HDMI sources are used.


    In 1993, Onkyo became the first consumer home theater electronics brand to be THX-certified. With literally thousands of tests, before earning the THX-certification logo: no matter what input is used, no matter what combination of the many built-in features for the AVR, preamplifier, or amplifier, there can be absolutely nothing added, nothing taken away from the source material. The TX-RZ50 offers four distinct THX listening modes: cinema, gaming, music, and surround EX.

    IMAX Enhanced Mode

    A vital component of today’s premium home theater experience, this IMAX Enhanced certified AVR replicates the immersive audio and visual quality of IMAX theaters from the comfort of your living room. By allowing object-based audio to be precisely placed and moved in 3D space, in combination with proprietary algorithms optimizing video quality, you’ll experience a vibrant, lifelike experience just as the filmmaker intended.
