Shure Beta 98S Miniature Supercardioid Microphone

The Shure BETA 98/S is a compact, high-output, supercardioid condenser microphone for professional sound reinforcement and studio recording. Its extremely uniform supercardioid pickup pattern provides high gain before feedback and excellent rejection of unwanted noise. Its high maximum sound pressure level (SPL) makes it useful for a variety of acoustic instruments, including drums, percussion, piano, reed, wind, and string instruments. The BETA 98/S can also be used for amplified guitars.

The BETA 98/S includes a shockmount swivel adapter (BETA 98/S). The BETA 98/S is supplied with a windscreen, storage bag, preamplifier, and an interconnect cable. The preamplifier can be powered by any 48 Vdc phantom power supply.
