The EK Assistive Listening System is a closed loop broadcasting system designed to work with a localized wifi network and personal devices. It enables anything within about a 5 ft radius of the microphone to be broadcast via the network, enabling people who are not “up front” to hear what is going on.
An overview of the system, how to use it, and how to set it up is available at the link below: https://sites.google.com/members.eastkingdom.org/sca-als
The system currently travels with the royal thrones. If you would like to have it set up at your local royal progress event, please coordinate with Their Majesties.
