The AMBEO Soundbar Max is Sennheiser's flagship single-piece Atmos bar, with thirteen drivers powering a 5.1.4-channel virtual surround field calibrated to your room. Its rear jack pack is the most generous in the AMBEO line: a single HDMI 2.1 eARC output to the TV plus three HDMI 2.0 inputs that pass 4K HDR through, an optical TOSLINK input, a stereo RCA aux input, a mono RCA subwoofer pre-out, a Gigabit Ethernet jack and a USB-A service port. The bar still uses a detachable 2-prong IEC C7-to-C8 figure-8 mains cord, despite the 250 W amplifier section.
Flagship 5.1.4 virtual Atmos bar with HDMI 2.1 eARC, 3x HDMI 2.0 inputs, optical, RCA aux, sub pre-out, Gigabit LAN, IEC C8.
