Start your new entertainment life in the media room, where the Onkyo TX-RZ50 passes 8K HDR video to your display via HDMI®—optimized for lag-free gameplay— and feeds Dolby Atmos® or DTS:X® sound to your 5.2.4-ch speaker system with high-current power behind it. Move to another space and music follows with three-zone powered audio and the SMART AV Receiver suite controlled by voice with easy access to streaming services. The AVR fits into your Sonos system and plays to headphones over bidirectional Bluetooth® wireless technology. With 75 years of hi-fi knowhow elevating Onkyo's THX® Certified Select and IMAX® Enhanced certified RZ Series custom amp design, music, film scores, and game soundtracks thrill with emotion, sound perfected by Dirac Live® Room Correction. This AVR has features others don’t, such as front-to-height stereo switching for background listening, DSP vocal/dialog enhancement, My Volume presets, and an OSD function that compares source data to output settings so playback can be optimized before entertainment kicks off.

The Onkyo RZ50 is by far one of the best values in the home theater receivers category. It has 9 powered channels included with preamp outputs for 11 plus 2 subs allowing you to add a power amp later to go with a full-blown 7.2.4 Dolby Atmos speaker configuration.

All 6 HDMI inputs are 8K HDCP 2.3 with two independent outputs that are both 8K (unless you use one for zone 2, then the second one will be limited to 4K) with eARC on the main one.

Onkyo has always been known for leading the pack with useful features and the RZ50 is packed full of them. You have app control, voice control, several ways to get streaming music into it, and bidirectional Bluetooth so you can also send the sound to a pair of headphones for late-night listening. A pretty unique feature that Sonos ecosystem fans will enjoy is the ability to connect a Sonos Port and it will show up in the Sonos app — you’ll have full control within the Sonos app, and you can add up to 3 to the RZ50!

But, the big reason for the success of the RZ50 is the fact that it has Dirac Live. Dirac has been a favorite room correction system of audio connoisseurs for almost a decade, but it has previously only been found in only the much more expensive units. You’ll see it in things like the Datasat RS20i, which sells for over $20k! To be able to get this great system for the price of the RZ50 is pretty incredible. The unit comes with a microphone for setup, but if you are serious about implementing Dirac properly, we suggest you purchase an aftermarket mic like the MiniDSP for around $100.

We really like the fact you can just add a 2 channel power amp and go to a full 11 channel immersive Dolby Atmos system and with all of the preamp outs, easily add more power down the road if necessary. There are some home theater receivers that sound better, but nothing we know of has all of these great features for the price of the Onkyo RZ50.

Details & Specs

IMAX Enhanced uses DTS:X® technology optimized for the IMAX signature experience and reproduces the full dynamic range of IMAX theatrical mixes. IMAX Mode delivers IMAX Enhanced content as the filmmakers intended.

THX® Certified Select theater-reference sound

Experience the same reference volume of a commercial theater in rooms where the screen-to-seat distance is about 12 ft. (3.5 m). Certified receivers must pass 2,000 bench tests in 75 categories.

Welcome to 8K Ultra HD with the latest HDMI®

Onkyo TX-RZ50 Features defined in HDMI 2.1 enable 8K/60p passthrough to a compatible display. As well as HDR10 and HLG, HDR10+ and Dolby Vision formats optimize brightness, contrast, and color frame-by-frame. All HDMI terminals support HDCP 2.3, while eARC on Main Out passes multichannel audio (including Dolby Atmos® or DTS:X) from TV to AVR for decoding and amplification. QMS (Quick Media Switching) reduces screen blanking when switching HDMI sources. Note: features defined in HDMI 2.1 supported on HDMI inputs 1–6, Main Out, and Sub/Zone 2 Out in Sub Mode output.

Experience lag-free gameplay

Transform virtual worlds with 3D sound and get a competitive edge with all-new HDMI features for gamers. VRR (Variable Refresh Rate), ALLM (Auto Low Latency Mode), and QFT (Quick Frame Transport) eliminate lag, stutter, and frame-tearing for more fluid and responsive gameplay. Note: features supported on HDMI inputs 1–6, Main Out, and Sub/Zone 2 Out in Sub Mode output.

Together with MAIN, Zone 2 and Zone 3 DACs support D/A audio playback (including HDMI, SPDIF, and NET) in three rooms. You can sync the same track or play different songs in each room using Onkyo Controller to manage your entertainment. Note: Zone 3 supports analog/NET only. Zone 2 HDMI audio available via inputs 1–3. HDMI and SPDIF support PCM only.

5 GHz/2.4 GHz Wi-Fi® supports 802.11ac standard

Isolated 1.8 GHz quad-core SoC performs multiple processing tasks at once. It evolves network functions and supports the 802.11ac (2×2 MIMO) standard for stable multi-room audio streaming. Note: some countries or regions have regulations that affect wireless signal strength and the use of Wi-Fi channels.

Bidirectional Bluetooth® wireless technology

Send or receive audio via Bluetooth wireless technology. Stream from your laptop, digital audio player, or mobile to the receiver over SBC or AAC, or share what’s playing in the main zone* to a pair of wireless headphones using SBC, aptX, or aptX HD codecs.* Audio via Chromecast built-in and Works with Alexa excluded.

Convenient Zone 2 and Zone B pre-/line-out

RCA pre-/line-out has two modes: Zone 2 supports connection of active speakers or a hi-fi system and can sync D/A audio in MAIN and Zone 2 or play a different source in each. Zone B plays MAIN audio through compatible wireless headphones via a connected headphone dock. Note: Zone 2 mode supports HDMI audio via inputs 1–3. SPDIF and HDMI support PCM only. Zone B mode is line-level only and supports encoded or PCM signals (all inputs) in MAIN and Zone B.

Dirac Live® Room Correction

Onkyo TX-RZ50 Dirac Live analyzes your audio system and listening environment by examining acoustic data measured with a setup mic. It corrects both the timing and amplitude aspects of sound coloration using a mixed-phase correction filter throughout the listening area, not just a particular zone. Correction is performed automatically using a proprietary app for smartphone or tablet*. Dirac Live improves staging, localization, clarity, voice intelligibility, and bass response. * Mobile device and AVR must be connected to the same local network.

Flexibility for customized setups

Connect an external power amp or motorized projector screen via the AVR’s 12 V trigger output and power them up automatically with your AVR, with CEC performing the same task for media players over HDMI. An IR repeater input lets you conceal the AVR away from the screen, ideal for bespoke theaters. Ethernet and RS-232 terminals integrate the AVR into your automation system, with the former supporting setup and web browser control via PC.
