ONKYO TX-RZ50

The Onkyo TX-RZ50 is a 9.2-channel surround AV receiver that belongs to the brand’s high-end lineup, offering cutting-edge technology for both audio and video. It supports advanced audio decoding formats such as Dolby Atmos and DTS:X, ensuring an immersive, three-dimensional sound experience. On the video side, it is IMAX Enhanced certified and compatible with 4K at 120 Hz signals, thanks to its HDMI 2.1 connectors, making it an ideal choice even for the latest and most demanding video games.

One of the model’s key strengths is its Dirac Live room correction system, considered one of the most effective on the market. This feature allows for precise speaker calibration based on the room’s configuration, using the included wired microphone or, for more advanced calibration, via a dedicated app on PC or Mac with an external USB microphone. Room correction is crucial in surround systems with multiple speakers, as it balances sound intensity, synchronizes timing and acoustic wave phase, and corrects frequency response—ensuring balanced, coherent sound reproduction that enhances every detail.

In terms of connectivity, the TX-RZ50 stands out for its integrated multi-zone streaming capabilities, allowing simultaneous audio and video transmission to two different areas of the home. With support for Apple AirPlay, Amazon Alexa, Google Assistant, and other smart home systems, the receiver can be seamlessly integrated into a smart home environment, with Zone 1 supporting up to 8K at 60 Hz and Zone 2 up to 4K at 120 Hz. Additionally, music can be streamed directly through the receiver, offering great flexibility for modern users.

The IMAX Enhanced mode further elevates the movie-watching experience, delivering remastered 4K HDR visuals and powerful, accurate sound faithful to the intentions of filmmakers and sound designers—for a top-tier audiovisual experience. The Zone 2 HDMI switching feature enables simultaneous distribution of two high-quality video signals to different rooms, such as watching 8K 60 Hz content in one room and 4K 120 Hz in another, significantly increasing system versatility.

The Onkyo TX-RZ50 also offers bidirectional Bluetooth connectivity: it can receive audio signals from mobile devices compatible with AAC or SBC codecs and simultaneously transmit audio to Bluetooth headphones, providing a fully wireless and uncompromising listening experience.
