4-Port eARC 8K Audio Extractor Switch

This 2-in-1 accessory combines a four-input HDMI 2.1 switch with an eARC audio extractor. It connects up to four source devices to one 8K or 4K@120Hz display while sending full eARC audio to a soundbar or AV receiver. Gamers and home-theatre users who need both switching and high-bitrate audio extraction in a single unit will find it suitable. It does not serve setups that require more than four inputs or extraction from non-eARC sources.

Thermals noise and power

The unit runs from an external dual-voltage power supply with a US plug and an included international adapter. No active cooling is fitted, so operation is silent and heat output is minimal in normal use. Power draw is limited to the supply rating and the 48Gbps HDMI 2.1 throughput. There are no fan curves, temperature thresholds or acoustic figures to consider.

Upgrade path

It replaces a basic HDMI switch that cannot pass eARC or an extractor that only handles ARC. The jump is worth it when moving to a soundbar or receiver that supports Dolby Atmos, DTS:X or LPCM 7.1CH over eARC and the display needs 8K or 4K@120Hz passthrough with HDR10+ and Dolby Vision. It does not help installations that lack eARC on the audio side or that require HDCP 2.2-only compatibility.

Questions about this item

How do I install the Orei 4-port eARC 8K extractor and what step do people often miss?

Connect up to four HDMI 2.1 sources to the inputs, run one HDMI 2.1 cable to the 8K or 4K@120Hz display, and link the eARC output to your soundbar. The step many miss is enabling CEC on every source and the display so the switch changes ports automatically.

What maintenance or replacement will the extractor need later?

No internal parts require scheduled maintenance. If the dual-voltage power supply or the supplied US plug with international adapter fails, replace only that external adapter — the main unit has no user-serviceable components.

What limit appears first during sustained 4K@120Hz gaming with eARC audio?

The 48Gbps HDMI 2.1 bandwidth ceiling is the first hard limit; it caps video to 4K@120Hz with HDR10+ or Dolby Vision while passing LPCM 7.1CH, Dolby Atmos, or DTS:X to the soundbar.
