4K HDMI Audio Extractor Splitter

The AUBEAMTO 4K HDMI Audio Extractor Splitter takes a single HDMI input and delivers one HDMI output while simultaneously extracting audio to optical Toslink SPDIF, coaxial, 3.5 mm analogue jack and a dedicated HDMI audio port. It is built for installers and home-cinema owners who need to feed a modern 4K source into an older AV receiver or soundbar that lacks HDMI 2.0 inputs.

18 Gbps HDMI 2.0 bandwidth with HDCP 2.3

The decisive specification is the 18 Gbps HDMI 2.0 path that carries 4K at 60 Hz with HDCP 2.3 and 10-bit HDR pass-through. Without this bandwidth the extractor would force a lower resolution or fail on protected 4K streams, so it is the single figure that determines whether the unit matches a given source and display chain.

Continuous 4K 60 Hz operation

A 5 V 1000 mA power adapter is included, allowing the extractor to maintain stable 18 Gbps throughput and active audio decoding over long viewing sessions without the signal drops or handshake losses that can appear on bus-powered alternatives during extended playback.
