Performance

Audio Performance

From the moment you power it on, the Onkyo TX-RZ50 impresses with its clarity, depth, and dynamic range. Whether you’re listening to classical music or watching an action-packed blockbuster, the amplifier’s 120 watts per channel ensure clean, distortion-free output even at high volume levels. The unit’s Class AB amplification balances warmth with control, ideal for both movies and music.

Dirac Live room correction is the standout feature. Unlike traditional EQ systems, Dirac corrects impulse response and frequency response, resulting in vastly improved imaging, dialog clarity, and bass accuracy. The full version of Dirac Live included with the TX-RZ50 sets it apart from competitors that often include a limited version or none at all.

Surround Sound and Immersion

Thanks to Dolby Atmos, DTS:X, and THX Certification, this receiver truly excels in surround environments. Sound objects are moved seamlessly between speakers in a 7.2.4 setup, immersing the listener in a 3D audio landscape. Even in simpler 5.1 or 7.1 setups, the receiver uses the Dolby Atmos Height Virtualizer to simulate overhead effects, which is especially useful if you don’t have height channels.

Klipsch Optimize Mode is another highlight for users with Klipsch speakers. By choosing the speaker model in the setup menu, the receiver applies calibrated crossovers optimized for that specific model—ensuring a more accurate frequency blend between the drivers and subwoofer.

Video Performance

Gaming and 8K video lovers will be delighted by HDMI 2.1 support, including 8K/60Hz and 4K/120Hz pass-through. The TX-RZ50 supports eARC, ALLM, VRR, and QFT, which are essential features for next-gen consoles like the PS5 and Xbox Series X. The video processing chain handles HDR10, HDR10+, Dolby Vision, and HLG with zero lag or color shift.

Streaming and Wireless

With built-in Bluetooth, AirPlay 2, Chromecast, and Spotify Connect, the receiver doubles as a powerful streaming hub. Wireless connectivity is stable and sound quality via aptX HD Bluetooth is excellent—even critical listeners will appreciate the 24-bit resolution over aptX HD.

The “Works with Sonos” certification adds convenience. With a Sonos Port (sold separately), the TX-RZ50 can integrate seamlessly into a Sonos ecosystem, including features like Volume Pass-Through, input switching, and synchronized multi-room playback—all controlled via the Sonos app.
