The Lithe Audio Link Pack will allow you to connect multiple master Lithe Audio speakers together. You can combine the standard and IP44 speaker for bedroom + en-suite setups. Compatible with: Bluetooth Standard Bluetooth IP44 Please note that all Lithe Audio speakers sold from June 2023 include the optical audio link. If you are linking to a speaker purchased prior to this date it may have the older analog connections. In this case please contact us for advice. LITHE LINK The Lithe Link system allows you to interlink up to three Lithe Audio master speakers. It can be wired in two ways for different applications: Half Loop: Speaker 1 wires into speaker 2. If you connect your Bluetooth to speaker 2 then only speaker 2 will play, if you connect to speaker 1 then all four will play. This is ideal if you want to do a kitchen + dining room and have some control over which speakers play. Full Loop: Speaker 1 wires into speaker 2, then speaker 2 wires back into speaker 1. When you connect your Bluetooth to either speaker, all speakers will play the same music at the same time. The kit comes with enough cables to do a full loop and we always recommend wiring all cables regardless of whether you plug them all in or not.
