LEA Professional Offers Open API Protocols for Enhanced Audio Systems Integration

LEA Professional, the startup turned industry player in the pro audio market, today announced new firmware for the company’s LEA Professional Connect Series amplifiers, including two new open API protocols.

According to Bradley Drummond, Director of Application Engineering & Consultant Relations at LEA Professional, the two new open API protocols have been launched in the new firmware version 2.0. The first utilizes WebSockets and the second is TCP based. All control and sensor elements in the amplifier WebUI can now be connected to in both API’s. This includes all DSP parameters, level meters, clip and fault indicators, power supply information and many 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,” said Drummond. “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 explained 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 easily 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 customers to integrate the Connect Series amplifiers with 3rd party equipment to create an almost limitless, custom AV solution.

“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” says Blake Augsburger, Founder and CEO of LEA Professional.
