Use the mics you already have... but now you can use them wirelessly. Just plug the transmitter in your mic and the receiver into your mixer and stand wherever you want, move around, and still have a great signal. I tested this out with my SM58 and would have no problem using this in a live setting. You could also use it with a guitar rig if you have DI box output. I like the small size and ease of use to set up. Six channels to choose from and super simple to dial them in. In fact, I look forward to using this at an event this weekend where I am setting up a portable sound system.
