HDMI 2.1 Splitter with Audio Extraction

This BYTECC 102ER device splits a single HDMI source to two displays while extracting audio to optical and analogue outputs. It supports video up to 8K at 60 Hz and 4K at 120 Hz with 40 Gbps bandwidth. The unit handles LPCM 7.1, Dolby Atmos and DTS:X formats for immersive sound. Ideal for home cinema or presentation setups needing simultaneous video and separate audio routing.

Replaces Basic Splitters Lacking Audio Breakout

Standard HDMI splitters pass audio only through the video outputs, forcing reliance on display speakers or HDMI audio return. This model adds dedicated SPDIF TOSLINK and stereo RCA outputs with internal DAC conversion. The jump is worth it when connecting a source to a projector or monitor without speakers, or when feeding a legacy AV receiver that lacks HDMI inputs. It also provides EDID management and RS-232 control for installation flexibility.

Limited by HDMI 2.1 Bandwidth

The 40 Gbps ceiling caps 8K signals at 60 Hz and 4K at 120 Hz without compression. Connected displays and cables must match these specifications to achieve the advertised resolutions. Audio extraction via SPDIF is restricted to LPCM 5.1 at 96 kHz or compressed Dolby and DTS formats; full 7.1 LPCM or lossless formats remain HDMI-only. ARC return function depends on compatible sink devices. Long cable runs may reduce achievable resolution or stability.

Questions about this item

What physical connections does the 102ER splitter need for power and signal?

The unit requires an HDMI 2.1 input from the source, two HDMI outputs for displays, plus SPDIF TOSLINK and stereo RCA connectors for extracted audio.

Which step do installers most often miss when setting up the 102ER?

Selecting the correct EDID mode so the source recognises both displays and enables 8K 60 Hz or 4K 120 Hz output.

What ongoing maintenance does the 102ER audio extractor require?

No scheduled maintenance; only reseat cables or power-cycle the unit if audio drops or video handshake fails.
