The QR-1 is the perfect tool for expeditious swapping of microphones in the studio or onstage. The bottom half threads onto a 5/8 microphone stand while the top half threads into a 5/8 threaded microphone clip. To disconnect the two, simply pull down on the lower half while lifting up on the top half. Buy a couple, toss them into your connector catch-all box and you will be glad you did.
