The DR 330 is a dual element ribbon and dynamic microphone featuring a Micro-Metal alloy diaphragm treated for protection against corrosion and unaffected by temperature changes. The two elements combined provide a cardioid polar pattern response while when only the ribbon element is used the polar response is bidirectional and with the dynamic only selected it is omnidirectional. The polar patterns can be selected by changing linkage bars. The microphone has a built-in shock-proof mounting with lock-latch and swivel. Includes 12.5 ft. single-conductor shielded rubber covered cable, black leatherette-covered storage box, velvet covered rubber cushioned interior.
