Every one of the nine HDMI ports on this 9.4-channel receiver runs at full HDMI 2.1 bandwidth — all six inputs and all three outputs support 8K@60Hz and 4K@120Hz passthrough. That's a standout feature in the mid-range segment where many competitors limit 8K to just two or three ports. Four independent subwoofer pre-outs allow precise bass management across multiple subs. Dual optical and dual coaxial digital inputs cover legacy source components, while a front-panel USB port handles hi-res audio up to 24-bit/192kHz.
9.4-channel 8K AV receiver with six HDMI 2.1 inputs, three outputs, and HEOS streaming.
