The C519 professional miniature condenser microphone clips gently onto the bell of a trumpet, saxophone, trombone, tuba, didgeridoo or any other wind instrument. Its tight cardioid polar pattern makes the C519 an ideal tool for use near monitor wedges, and its flat frequency response delivers a natural, powerful and clear sound. The MPAV from C519 M features an integrated, switchable bass cut for adjusting the microphone s frequency response.
