Audio Transmission Only

This kit extends eARC and ARC audio from a TV back to an AV receiver over a single Cat 5e or higher Ethernet cable up to 100m. It supports high-bitrate formats including Dolby Atmos and DTS:X plus lossless Dolby TrueHD and DTS-HD Master Audio. Both transmitter and receiver units require power via Micro USB and the package includes IR emitter, IR receiver and RS232 Phoenix connectors.

Home Theater Installers

Suited for installations where the AV receiver sits far from the display and only the audio return channel needs bridging. Buyers who need video extension alongside audio should look at a different product because this unit transmits audio only. The kit also provides bi-directional IR, RS232 and CEC pass-through for remote control of the connected equipment.

100m Cat Cable Reach

The single specification that decides fit is the maximum extension distance of 100m over Cat 5e/6/6a/7 cable. If your cable run exceeds this length the extender will not work and a fibre-based solution is required.

Questions about this item

How far can this kit reliably carry Dolby Atmos eARC audio from my TV to the AV receiver?

The extender kit transmits full eARC audio, including Dolby Atmos and DTS:X, up to 100 metres or 330 feet over a single Cat 5e/6/6a/7 cable.

What cable standard is required and does it limit the audio formats I can send?

A single Cat 5e or higher Ethernet cable handles the full eARC bandwidth, so object-based formats like Dolby Atmos and lossless codecs such as Dolby TrueHD pass through without compression.

What physical connections and mounting options come in the box for installation?

The kit includes transmitter and receiver units, two 5 V 1 A power adapters with Micro USB cables, IR emitter and receiver, two 3.5 mm 3-pin Phoenix connectors for RS232, and four mounting brackets with screws.
