Operating up to 100ft away, the ULXD14 is a digital wireless bodypack system that allows you to eliminate cables from your microphone on stage. The body pack wireless transmits the signal in 24bit quality with excellent signal-to-noise ratio, and security measures such as encryption, as well as having advanced battery technology resulting in 12 hours of performance time. The receiver unit has up to 60dB of gain, and automatically scans for the cleanest frequency available. This system works with a wide selection of Shure microphones and is particularly popular for public speaking, where a clip-on lapel microphone may be worn.
