⚡ At a Glance
- • Video Pass-through: 4K@30Hz HDMI pass-through keeps the original video and audio stream intact
- • Best for: Home cinema enthusiasts and gamers who want separate audio routed to an amp
- • Not ideal for: Setups that require ARC/eARC or using a TV as the HDMI signal source
Separates HDMI audio to optical digital and 3.5mm stereo while passing the HDMI video signal at up to 4K@30Hz. Supports selectable PASS, 2CH and 5.1CH audio modes for different speaker systems.
Clear Hi‑Fi Playback – Thanks to optical and 3.5mm stereo outputs
The unit extracts the audio layer from the incoming HDMI signal and sends it out via an optical digital (SPDIF) port and a 3.5mm analogue output. The source device should be set to PCM/LPCM when using 2CH mode, and SPDIF carries multichannel passthrough when available from the source.
Connect an amplifier or powered speakers directly for superior sound compared with TV speakers. Ideal for users who want the display to remain the main video output while routing audio into a dedicated sound system.
Preserve Native Video Quality – With 4K@30Hz HDMI pass-through
The HDMI output relays the original HDMI signal to a display or projector at up to 4K@30Hz, with a recommendation to use HDMI cables shorter than 3m for reliable results. Video and audio can be routed to different destinations without rescaling the picture.
Keep full-resolution video on a TV or projector while sending audio to external speakers. Useful for film nights, presentations or gaming where picture quality must not be compromised.
Flexible Multichannel Support – With selectable PASS, 2CH and 5.1CH modes
Three audio modes let the source either pass through its native audio (PASS), downmix to two-channel PCM (2CH) or pass multichannel 5.1 when supported by source and speakers. 7.1CH and Atmos content will stream via HDMI OUT only, with SPDIF not supporting Atmos 7.1.
Match the extractor to the capabilities of an amplifier or soundbar without guesswork. Provides practical flexibility for mixed setups, from stereo hi‑fi to multichannel home cinema.
