The A56D universal drum mounting system can be used to position microphones virtually anywhere on drum rims, microphone stands, even cymbal stands. Designed with captive parts to prevent the loss of individual pieces, the A56D is small, secure and can be used with any standard microphone, making it a great tool for both stage and studio environments. It fits stand adapters with a 5/8-inch 27-thread. An L-adapter extension curves at a 90 degrees angle for optimum microphone placement. The clamp fits drum rims measuring from 0.5-inch (12.7mm) to 2.25-inch (57.2mm) in height or on cymbal stands measuring from 0.375-inch (9.5mm) to 1.125-inch (28.6mm) in diameter.
