Product OverviewThe Lightware HDMI-4K De-embedder extracts embedded audio from an HDMI 4K signal and outputs it as discrete analog and digital audio — while simultaneously passing the HDMI video signal through unmodified. Designed for professional AV installations where audio must be routed independently of the video path — such as feeding an audio system, DSP processor, or amplifier from an HDMI source that would otherwise bypass the audio infrastructure. Available from Creation Networks. Product DescriptionModern AV sources — PCs, media players, Blu-ray players, cable boxes — embed audio in the HDMI stream. When these sources feed a display directly, audio is handled by the display. But in professional AV installations, audio must be routed separately to a DSP processor, audio matrix, amplifier, or assistive listening system. The HDMI-4K De-embedder solves this by tapping the HDMI signal, extracting the embedded audio, and outputting it on analog (balanced or unbalanced) and digital (S/PDIF or AES/EBU) connectors — while the HDMI output continues the video (and audio) to the display. This allows the same HDMI source to simultaneously feed the display and the building audio system without requiring a separate audio connection from the source device or AV control system intervention. Key Features HDMI loop-through output — video and embedded audio continue to the display unaffected Extracts embedded audio from HDMI 4K sources Analog audio output — balanced and/or unbalanced Digital audio output — S/PDIF (optical and/or coaxial) and AES/EBU Supports LPCM 2.0 audio extraction Compact form factor for rack shelf or surface mounting No signal processing on the HDMI video path — transparent pass-through No configuration software required for basic operation Typical Applications Conference rooms — extracting HDMI audio from a presentation laptop to feed the room's installed audio system Lecture halls — routing HDMI source audio to the assistive listening system and DSP processor independently Boardrooms with separate video display and audio systems requiring a common HDMI source Hospitality AV — routing in-room HDMI content audio to the installed ceiling speaker system Broadcast and production — splitting HDMI program audio for monitoring, recording, or IFB systems Digital signage with audio — sending media player audio to a separate amplifier or zone Technical Specifications Specification Detail Model HDMI-4K De-embedder (91330008) Function HDMI audio de-embedder with loop-through HDMI Input 1x HDMI (4K compatible) HDMI Output 1x HDMI loop-through Analog Audio Output Balanced / unbalanced stereo Digital Audio Output S/PDIF (optical/coaxial), AES/EBU Audio Formats Supported LPCM 2.0 Max Video Resolution 4K (pass-through) Power DC (external supply) Manufacturer Lightware Visual Engineering Part Number 91330008 Competitor Comparison Criteria Lightware HDMI-4K De-embedder Crestron HD-DA8-4KZ-E Extron DA6 HDMI 4K Plus Primary Function Audio de-embedding with HDMI loop-through HDMI distribution amplifier (8 outputs) with de-embedding HDMI distribution amplifier (6 outputs) with de-embedding HDMI Outputs 1 (loop-through) 8 6 4K Support Yes — 4K pass-through Yes — 4K@60Hz 4:4:4 Yes — 4K@60Hz Analog Audio Output Yes Yes Yes Digital Audio Output S/PDIF, AES/EBU S/PDIF S/PDIF, AES/EBU HDCP 2.2 Yes (4K pass-through) Yes Yes Form Factor Compact standalone 1RU rack 1RU rack Use Case Single-point audio extraction Multi-display distribution with audio Multi-display distribution with audio Frequently Asked Questions Does the HDMI output continue carrying audio after de-embedding? Yes. The HDMI loop-through output carries the original HDMI signal including the embedded audio, so the connected display receives both video and audio normally. The de-embedder extracts a copy of the audio — it does not remove it from the HDMI stream. What audio formats does the de-embedder support? The unit extracts LPCM 2-channel (stereo) audio. Bitstream formats (Dolby Digital, DTS, Dolby TrueHD, DTS-HD MA) are not extracted as discrete audio — the source must be set to output LPCM if discrete analog or digital audio extraction is required. Can it de-embed audio from a 4K HDR source? Yes. The HDMI input and output support 4K. The de-embedder does not process or modify the video signal — it passes through transparently regardless of HDR, resolution, or color space. Is any configuration required? No configuration is required for basic audio de-embedding and HDMI pass-through. Power on the unit and connect the HDMI source, HDMI display, and audio system. What is the difference between using a de-embedder versus taking audio from the source device? Many source devices (PCs, media players) have separate audio outputs, but in AV installations the source is often wall-plate or rack-mounted without convenient access to its audio outputs, or the source may not have analog audio outputs at all. A de-embedder provides a standardized extraction point on the HDMI signal path, independent of the source device type. Contact Creation Networks for system design guidance.
