Simplecom CM423v3 HDMI Audio Extractor with Optical SPDIF, 3.5mm Stereo and ARC 4K@60Hz

The Simplecom CM423v3 is a compact HDMI 2.0b audio extractor designed for professional and home‑theatre environments. It passes through 4K Ultra HD video at 60Hz while extracting high‑resolution audio to both an optical SPDIF port and a 3.5 mm stereo jack, allowing simultaneous dual‑output for 2.0‑channel sound. ARC (Audio Return Channel) support enables direct audio extraction from ARC‑compatible TVs, and HDCP 2.2 compliance ensures compatibility with protected content. Powered via a micro USB connection, the device is plug‑and‑play and requires no additional drivers. It supports a wide range of audio formats including Dolby Digital, Dolby TrueHD, DTS‑HD, PCM and LPCM, making it ideal for connecting legacy speaker systems or soundbars that lack HDMI inputs. The lightweight 75 × 55 × 25 mm unit fits neatly behind AV equipment for a clean setup.
