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.

Une merveille, Onkyo est clairement de retour et frappe fort avec la gamme RZ

Vincent

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.

L’amplificateur Onkyo TX-RZ50 est une excellente base pour mon installation home cinéma. Je l’utilise en parallèle avec un ampli Rotel RMB-1555 pour alimenter la partie 5.1, et l’ensemble offre une dynamique impressionnante, une scène sonore large et un traitement audio précis, notamment avec Dirac Live. La connectivité est complète, les fonctions HDMI 2.1 sont à jour, et la gestion des sources est fluide. Un ampli polyvalent, puissant et parfaitement adapté aux installations évoluées.
