Digital wireless is crystal clear and focused. You won't have to worry about dodgy signals and the hassle of setting up units. With the touch of a button, the Shure ULXD1 will sync up with its intended receiver. Auto-gain ranging constantly watches and takes care of the gain signal of your unit. The Shure ULXD1 uses 24-bit/48kHz digital audio, which the live sound gurus here at Sweetwater consider to be among the best in the industry.
