With the Positive Grid Spark LINK XLR, annoying cable clutter and loose contacts are a thing of the past. The compact system is not only particularly space-saving but also easy to use. Simply plug the transmitter and receiver units into the corresponding connections on the microphone and the mixing console or PA system, switch them on and get started. The system can be used for up to six hours at a time and offers a transmission range of up to 21 meters, making it ideal for use in rehearsal rooms or on smaller stages. If several band members use the Spark LINK or interference occurs, four different channels are available to ensure clear signal separation.
