How Does Bluetooth Work?
Bluetooth transfers data between devices via short-range wireless technology operating on frequencies 2.4 to 2.485 gigahertz (GHz). In Bluetooth version 5 that distance can be up to 120 metres, but walls and other obstacles may reduce that distance.
Bluetooth devices automatically detect and connect to one another in pairs. There are 79 channels available for Bluetooth to use. Each pair of devices pick a random channel and if that's taken they will try another. Therefore you could have up to 8 rooms adjacent to one another each with their own Bluetooth pairing, and they will not interfere with one another.
Your device needs to be Bluetooth-enabled, and the PA system needs to have a Bluetooth receiver somewhere in the setup. It could be a feature of a CD player or wallplate linked to a mixer; within the mixer itself, or if you're not using a mixer it could be a feature of your speakers or portable PA system.
You can only link one Bluetooth device to a paired Bluetooth receiver at a time - if you think about it, you only want one person to be able to send their songs to the PA system, or a battle would ensue!
