Tech Specs

The next-generation Hearing HotSpot™ system features everything you need to stream multiple channels of audio in real time over an enterprise Wi-Fi network. Once a system is installed in a venue, the software license is activated by Williams Sound based on the number of channels (up to 32 per server box, either Analog or Dante™) at that venue. Venue controlled advertising/messages, made available through simple web portal and system updates, are delivered to the venue without on-site visits.
