BETA Series Clamp-on Microphone for Woodwinds, Brass, and Percussion

The Beta 98H/C�is a premium cardioid condenser instrument microphones that clamps onto the bell of wind instruments or onto the rim of percussion instruments. The integrated gooseneck and ratcheting swivel joint allows the mic to be easily positioned and secured, and an isolation shock-mount reduces the transmission of instrument 'key noise' and other mechanical noise. A gooseneck angle brace is included to provide better retention of the microphone placement during more active performances.
