OREI eARC Audio HDMI Extender 165 ft over CAT6

OREI eARC Audio Extender lets you send HDMI ARC/eARC audio up to 165 ft over a single CAT5e/6/7 cable for clean, long-distance sound from a TV back to an AV receiver or amplifier.

Move audio from a wall-mounted TV to an out-of-sight receiver, amplifier, or sound system without running bulky HDMI cables. The OREI eARC-EX165-K bundle includes a sender and receiver pair, dual power adapters, and is designed for professional AV installs where the television and audio equipment are in different rooms or a media closet. Its metal housing and plug-and-play setup make it suitable for both residential and commercial installs.

How does this device transmit eARC/ARC audio across rooms?

The OREI unit captures HDMI ARC or eARC audio from your TV’s HDMI port and converts it to travel over a single CAT5e/6/7 cable to the receiver unit. At the receiving end, audio is converted back to HDMI for your amplifier or AV receiver, preserving multichannel formats supported by the TV and source.

• Supports PCM 2.0/5.1/7.1, Dolby Digital, Dolby Digital Plus, Dolby TrueHD, DTS, DTS-HD MA, Dolby Atmos where supported.
• Single CAT cable run up to 165 ft (50 m) between sender and receiver.
• Maintains HDMI ARC/eARC audio return channel functionality over long distances.

What do I need for installation and compatibility?

Use any standard CAT5e, CAT6, or CAT7 cable to link the sender and receiver. The TV must support ARC or eARC on its HDMI ARC port to return audio. Power adapters are included for both units and a universal adapter is supplied for international use.

• One HDMI ARC/eARC-enabled TV and one AV receiver or amplifier with HDMI input.
• One continuous CAT5e/6/7 cable run, up to 165 ft (50 m).
• Included power adapters and simple HDMI connections for plug-and-play setup.

Will audio quality and formats be preserved?

This extender supports common multichannel audio formats used in home theater setups. It passes compatible PCM and lossless surround formats as allowed by the TV and source device over ARC/eARC, enabling dedicated receivers or processors to handle decoding and playback.

• Passes multichannel PCM, Dolby and DTS family formats where the TV and source allow.
• Relies on TV’s ARC/eARC implementation for negotiating format support with sources.
• Metal housing helps stable operation and reduced thermal impact in AV racks.

How does this fit into professional or wall-mounted TV installations?

The compact sender mounts near the TV and the receiver sits by the AV equipment, creating a neat, concealed installation without running HDMI through walls. A sturdy metal enclosure and included power supplies make it suitable for pro AV installations and clean residential setups.

• Compact footprint for behind-TV placement or within a media box.
• Durable metal case for heat dissipation in enclosed spaces.
• Plug-and-play wiring reduces installation time and complexity.

Who this is for: installers, home-theater enthusiasts, and homeowners who want their TV audio routed to a separate receiver, amplifier, or sound system without long HDMI runs. It’s ideal when the TV is wall-mounted or located in one room while the AV gear sits in a closet, AV rack, or another room—in short, any situation needing clean, reliable audio return over a single CAT cable.
