Abstract: A method for pairing and controlling multiple loudspeaker systems within a network. The network includes multiple control units, each having Bluetooth and RF chipsets, an MCU, and at least one transceiver. One control unit, the master unit, is operatively connected to a first loudspeaker system. A second control unit, the slave unit, is operatively connected to a second loudspeaker system. The master unit generates and records an IV key. The IV key and master unit identifying information are transmitted to, and recorded by, the slave unit. The IV key is then used to initiate communication between the master and slave units. Slave unit identifying information is transmitted to, and recorded by, the master unit. The master unit then transmits digital data to the slave unit, which relays the data to the second loudspeaker system. The first and second loudspeaker systems then simultaneously perform a task associated with the digital data.
