The AT8492PL magnetic piano mounting system is designed to work with the ATM350a cardioid condenser instrument microphone. The system includes an AT8491P magnetic piano mount and an AT8490L 9" gooseneck. The magnetic mount attaches to a piano's cast iron frame or other metal part, providing vertical or horizontal positioning that stays in place. The mount's base is lined with felt to prevent damage to the instrument. The strong, flexible gooseneck, which is held securely in the mount's socket by a locking screw, lets you position the mic where you want it and holds it there.
