The HDC-SWC11A is a premium 8K60 eARC Audio Adapter designed to extract high-quality audio from an HDMI source or a TV with ARC/eARC functionality. With support for HDMI 2.1 and a blazing 48Gbps bandwidth, this adapter de-embeds audio and outputs it via HDMI, S/PDIF (optical), or analog stereo (L/R) to AV receivers, amplifiers, soundbars, or 2.0/5.1CH sound systems.
Engineered for full compatibility with modern HDMI 2.1 features—including VRR, ALLM, QMS, QFT, and SBTM—it also supports the latest HDR formats and advanced audio passthrough such as Dolby Atmos, DTS:X, and LPCM 7.1. It is the ideal solution to make legacy audio equipment compatible with modern 8K TVs or eARC soundbars such as the SONOS ARC and Beam.
Built-in EDID management, signal equalization, and CEC pass-through further enhance installation flexibility and performance.
