Shure WB98H/C Beta 98 Clip-On Condenser Instrument Microphone 

The Shure WB98H/C (the wireless version of the 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 placement during more active performances.

The Shure WB98H/C features transformerless preamplifier circuitry, which improves linearity across the full frequency range.

The pickup pattern of the Beta 98H/C provides high gain-before-feedback and excellent rejection of unwanted noise.

Its high maximum sound pressure level (SPL) enables it to handle the extreme demands of brass, woodwind and percussion instruments.
