Wireless freedom which wont compromise on sound quality. The LD Systems U308 BPH Single Headset Mic Wireless System is a complete wireless audio solution designed for professional vocal and speech applications. The 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 a headset and bodypack transmitter 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.
