Models Beta 98H/C and WB98H/C User Guide Condenser Instrument Microphone 2001, Shure Incorporated 27B3102 (AC) Printed in Mexico
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.
ENGLISH FEATURES • • • • • • • • Tailored frequency response for open, natural sound reproduction Adjustable gooseneck and ratcheting swivel joint allow for optimal microphone positioning Gooseneck angle brace retains microphone placement in more active performances Compact, lightweight construction provides a low degree of visibility Designed for use in high SPL environments Uniform cardioid pattern provides for high gain-before-feedback and excellent rejection of ambient sound Interchangeable microphone
ENGLISH APPLICATIONS AND PLACEMENT The most common BETA 98H/C applications and placement techniques are described below. Keep in mind that microphone 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.
