Cheap wireless mic systems lock you to a fixed frequency, so when a local TV transmitter or another act's rig sits on your channel, you are simply out of luck. The SC-930UHF lets you re-tune. It runs on UHF (470-580 MHz) - the professional band - reaches 300 feet line of sight, and outputs on proper balanced XLR, all in an aluminium flight case with the batteries already included.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelectable Frequencies - the Whole Reason to Buy It:\u003c\/strong\u003e If you hit interference, you change channel.
