LEA Professional has announced new firmware — version 2.0 — for the company’s LEA Professional Connect Series amplifiers that includes two new open API protocols.

One protocol utilizes WebSockets while the second is TCP based. All control and sensor elements in the amplifier WebUI can now be connected to both API’s, including all DSP parameters, level meters, clip and fault indicators,
power supply information other items.

“The WebSocket API is geared more toward software and web programmers who are looking to integrate the Connect Series amplifiers with custom developed software,” says Bradley Drummond, director of application engineering and consultant relations at LEA. “The TCP protocol is aimed at more common integrations with third-party professional AV equipment. With these two new open protocols, we can help developers and integrators create powerful and unique experiences for their AV systems.”

Specifically, Drummond adds that the WebSocket communicates with a JSON-RPC command and response structure and supports GET, SET, SUBSCRIBE, UNSUBSCRIBE, and INFO commands. The TCP protocol supports GET, SET, SUBSCRIBE, and UNSUBSCRIBE commands. Many control and DSP products in the pro AV industry can send and receive TCP commands with basic programming.

In both protocols, elements of the amplifier can be controlled, and current values can be sent back from the amplifier. These two protocols allow users to integrate the Connect Series amplifiers with third-party equipment.

“The Pro AV market wants to choose the best in class products for each system and also want that system to be able to be controlled and monitored autonomously. With our newly released Open API platforms, the LEA Connect Series can now integrate into almost any AV system via TCP or Websocket commands and it’s exciting to be able to give integrators this powerful option for their projects,” concludes Blake Augsburger, founder and CEO of LEA Professional.
