The Ampetronic ILD9 Induction Loop Driver is designed to cover loop areas up to 500m². Several units can be connected together in Master Slave configuration for driving single turn loops covering much larger areas such as Cathedrals, sports halls and theatres. It can also be used for large conference rooms and other areas where specialised requirements apply. In these environments, the equipment can be used to drive phased arrays for low-spill operation. These specialised loop layouts can be designed by Ampetronic Ltd. who also supply the precision phase shifter needed for this work.
