Overview
- The Simplecom CM423v4 is a professional-grade HDMI audio extractor that solves a common AV connectivity challenge: extracting high-quality audio from HDMI sources to connect with external speakers, soundbars, or legacy audio equipment. Built to HDMI 2.0b standards, it supports up to 4K@60Hz resolution whilst simultaneously extracting audio, ensuring no compromise on video quality.
The device operates in two modes. In HDMI input mode, it extracts audio directly from source devices like media players or gaming consoles whilst passing the video signal unchanged to your display. In ARC/eARC mode, it captures audio from your TV's ARC-enabled HDMI port, making it ideal for connecting external audio systems to modern televisions.
With both optical SPDIF and analog stereo outputs, the CM423v4 works with virtually any audio equipment. It supports a comprehensive range of audio formats including Dolby Digital, Dolby TrueHD, DTS, and PCM, ensuring compatibility with contemporary and legacy systems alike. HDCP 2.2 compliance protects encrypted content, and USB-C power input keeps installation straightforward with minimal cable clutter.

FAQs
What is the difference between HDMI input extraction and ARC extraction modes?
HDMI input mode extracts audio directly from source devices (media players, consoles, set-top boxes) whilst passing video to your display. ARC mode extracts audio from your TV's ARC/eARC HDMI port, allowing you to send audio back to external speakers or soundbars connected to the extractor.
Can I use this with my older non-4K display?
Yes. The CM423v4 is backwards compatible with earlier HDMI versions and supports resolutions from 480i up to 4K@60Hz. It will work seamlessly with any display or ARC-enabled television.
Does it support Dolby Atmos or other advanced audio formats?
The CM423v4 supports Dolby Digital, Dolby TrueHD, DTS, DTS-HD, PCM, and LPCM. For Dolby Atmos via optical output, compatibility depends on your audio equipment and source content, as optical SPDIF has bandwidth limitations for object-based audio.
What power source does it require?
The extractor is powered via USB-C with a 5V/1A power supply. A USB power cable is included in the package, and it can be powered from any standard USB charger or power adapter.
Is HDCP-protected content supported?
Yes. The CM423v4 is HDCP 2.2 compliant, ensuring reliable playback of protected content from services like Netflix, Blu-ray players, and other encrypted sources.
Can I connect both HDMI and ARC modes simultaneously?
The device operates in one mode at a time. You select either HDMI input extraction or ARC extraction based on your audio source. Switching between modes may require manual configuration.
What cable distances are supported?
The maximum HDMI input cable distance is 10 metres using standard AWG26 HDMI cables. Longer runs may degrade signal quality and are not recommended.
