All six HDMI inputs on this premium 9.4-channel receiver are full HDMI 2.1, matching its sibling the Denon X3800H with 40Gbps bandwidth on every port for 8K@60Hz and 4K@120Hz passthrough. Four independent subwoofer pre-outs support sophisticated multi-sub bass management — a feature typically reserved for separates. The receiver pairs dual optical and dual coaxial digital inputs with five analog stereo inputs and a dedicated MM phono stage. An Ethernet port and front-panel USB round out the wired connectivity.
Premium 9.4-channel 8K AV receiver with six HDMI 2.1 inputs, three outputs, and HEOS streaming.
