Overview
- The Simplecom CM423v3 HDMI audio extractor solves a common problem: connecting modern HDMI video sources to audio equipment that lacks HDMI inputs. It extracts embedded audio from HDMI signals or directly from an ARC-enabled TV, then routes that audio to either optical or analogue outputs whilst passing the video through unchanged.
This adapter is HDMI 2.0b compliant and handles 4K@60Hz video resolutions without degradation, making it suitable for 4K gaming, streaming, and home theatre applications. It supports both compressed audio formats (DTS-HD, Dolby TrueHD, Dolby Digital) and uncompressed formats (PCM, LPCM), ensuring broad compatibility with modern content and audio systems.
Powered by a standard USB connection (5V/1A), the CM423v3 can draw power from a wall charger or directly from a TV's USB port, eliminating the need for additional power adapters. Its compact design allows it to sit discreetly behind entertainment systems without occupying much space.
