Audio-Technica LINK (*1) is a proprietary communication protocol developed by Audio-Technica. It leverages IP (Internet Protocol) technology for transmission of uncompressed multi-channel digital audio and for information control with minimal latency. One of the key advantages of Audio-Technica LINK is the ability to power Audio-Technica LINK endpoint devices, eliminating the need for a power cable or standard PoE switch.

The protocol allows the transmission of multi-channel digital audio signals from endpoint devices to be individually assigned to the input channels of Audio-Technica’s ATDM line of mixers. This flexibility enables efficient system audio routing and control.

One notable benefit of Audio-Technica LINK is a reduced number of audio cables required. By utilizing general-purpose LAN (Local Area Network) cables (*2), the protocol eliminates the need for multiple analog audio cables for multi-channel transmission. This significantly simplifies cable management and installation processes.

Another advantage of Audio-Technica LINK is its daisy-chaining capability. Multiple Audio-Technica LINK devices can be interconnected in a chain, making installation and setup even more convenient. This feature sets it apart from other IP technology-based communication protocols that typically require a star topology connection to an Ethernet (PoE) switch.

Audio-Technica LINK offers a variety of benefits, including uncompressed digital audio transmission, low latency, power for endpoint devices, reduced cable routing, and simplified installation through daisy-chaining. These features make Audio-Technica LINK a compelling communication protocol for professional audio applications.

*1 Audio-Technica LINK works only between Audio-Technica devices and cannot be used with general Network switches.

*2 LAN cables must be CAT 5e or higher and shielded with a conductor size of 24 AWG diameter or larger.
