Welcome to Ultra HD 8K with the Latest HDMI
The HDMI 2.1 standard offers a multitude of features, such as transmitting 8K/60p signals to a compatible screen. HDR10 and HLG, HDR10+, and Dolby Vision formats optimize the image by adjusting brightness, contrast, and colors frame by frame. HDCP 2.3 is supported by all HDMI terminals, while the main eARC output allows multichannel audio (including Dolby Atmos or DTS:X) to be transmitted from the TV to the amplifier for decoding and amplification. Additionally, the QMS (Quick Media Switching) function reduces the white screens that can occur when switching HDMI sources.
Dolby Atmos and DTS:X
Treat yourself to an immersive entertainment experience using Dolby Atmos and DTS:X audio formats that faithfully reproduce sound origins as you perceive them in real life and place them around your audience. With a 5.2.4 or 7.2.2 configuration, you can enjoy 3D sound or expand the system to 7.2.4 channels by connecting a stereo amplifier. You can also rediscover your favorite classic titles thanks to your height-adapted system with Dolby Surround and DTS Neural:X. These technologies analyze existing soundtracks to extract spatial cues and mix them for immersive 3D playback.
Enjoy a Lag-Free Gaming Experience
Optimize your gaming experience by utilizing the cutting-edge features of HDMI technology for gamers, including 3D sound, VRR (Variable Refresh Rate), ALLM (Auto Low Latency Mode), and QFT (Quick Frame Transport). By eliminating delays, stuttering, and image tearing, these features allow you to stay one step ahead of your competitors by playing more smoothly and responsively in immersive virtual worlds.

The Onkyo TX-RZ50 amplifier is an excellent foundation for my home theater setup. I use it alongside a Rotel RMB-1555 amp to power the 5.1 section, and together they deliver impressive dynamics, a wide soundstage, and precise audio processing, especially with Dirac Live. Connectivity is comprehensive, HDMI 2.1 features are up to date, and source management is seamless. A versatile, powerful amp that’s perfectly suited for advanced setups.
