The freedom of wireless without compromising on quality. The LD Systems U518 Double Headset Mic Wireless System is a complete wireless audio solution designed for professional vocal and speech applications. The True Diversity wireless system features an automatic scan function which finds the best free frequency whilst setup between transmitter and receiver is made simple with one-touch syncing. With 2 x headsets and 2 x bodypack transmitters the system is also ideal for situations where a hands-free performance is required. A cardioid polar pattern ensures high feedback resistance and the foam windscreen reduces interfering wind and breath noise. An OLED display allows for easy system monitoring with group channel signal and battery statuses and a squelch function ensures fail-safe operation.
