With 9 channels of amplification (110W per channel) and support for 8K/60Hz and 4K/120Hz passthrough, it’s a future-proof choice for cinephiles and gamers alike. The sound quality is outstanding, thanks to Dolby Atmos, DTS:X Pro, and IMAX Enhanced, creating an immersive 3D soundstage. Even without height speakers, Dolby Height Virtualization and DTS Virtual:X simulate overhead effects remarkably well. The inclusion of four subwoofer outputs ensures deep, room-filling bass, while the legendary Marantz HDAM circuitry provides warm, detailed audio reproduction. Setup is hassle-free with Audyssey MultEQ XT32, which optimizes sound for any room. The receiver also excels in multi-room audio, featuring built-in HEOS, Wi-Fi, and Bluetooth for seamless streaming via Spotify, Pandora, and more.

On the connectivity front, the Cinema 50 impresses with nine HDMI ports (6 in, 3 out), including eARC support and 8K upscaling.
