48Gbps HDMI 2.1 Audio Extractor: Extract high-quality audio from HDMI sources via HDMI, optical (S/PDIF), or analog outputs for soundbars, AV receivers, amplifiers, and speakers. Supports up to 48Gbps bandwidth and eARC/ARC audio formats including Dolby TrueHD, Atmos, DTS-HD MA, and LPCM 7.1. Optical output supports up to 5.1 only (no 7.1 downmix). Advanced eARC/ARC Compatibility: This HDMI audio extractor enables full eARC/ARC functionality, providing high-definition audio pass-through from TVs to sound systems, including Dolby Atmos and DTS formats. It's perfect for connecting high-end soundbars like Sonos ARC & Beam for an immersive sound experience. 8K/4K Video Support: Supports up to 8K@60Hz and 4K@240Hz video, along with features like VRR, ALLM, and QMS. The extractor is compatible with HDR formats like HDR10, HDR10+, and Dolby Vision for enhanced visuals. Versatile Audio Formats: Supports LPCM 5.1, Dolby TrueHD, Dolby Atmos, DTS-HD Master Audio, and DTS. It provides multiple audio output options, including optical, analog, and HDMI, for flexible audio setups. CEC/EDID Guidance: CEC behavior may varies by TV brand. The extractor features advanced EDID management and cable equalization to ensure reliable performance with your home theater setup. It does not include built-in volume control—please use your TV, soundbar, or AVR instead (earphones/headphones are not supported). If you experience power toggling or signal cutouts, try disabling CEC/auto power or setting a fixed input. Important Compatibility Notes: The OPTICAL port supports up to 5.1-channel audio only—it does not support 7.1 or downmix 7.1 audio. Older HDMI sources such as PS3 or Xbox 360 may not be compatible and could cause audio loss. The OUT TV (eARC) port must be connected to an eARC-compatible TV; some monitors that lack eARC may not work. Samsung Q-Symphony is not supported. For proper operation, connect stable 5 V power, and set your TV’s eARC = ON and Audio = Bitstream/Pass-Through. Cable Matters 48Gbps HDMI Audio Extractor with eARC
