ENGLISH GENERAL The Shure BETA 98H/C is a premium cardioid condenser instrumental microphone that clamps onto the bell of wind instruments or onto the rim of percussion instruments. The integrated gooseneck and ratcheting swivel joint allows the microphone to be easily positioned and secured in place, 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 place

ENGLISH APPLICATIONS AND PLACEMENT The most common BETA 98H/C applications and placement techniques are described below. Keep in mind that micro- phone technique is largely a matter of personal taste; there is no one “correct” microphone position. SAXOPHONE (see Figure 4): Clamp the microphone onto the bell of the saxophone, so the microphone is a few inches from and facing into the bell. This will produce a bright tonal balance while minimizing feedback and leakage. SOPRANO SAXOPHONE (see Fig
