Beta 98A
Miniature Cardioid Condenser Microphone |
|
Product Code: BETA 98A
Miniature Cardioid Condenser Microphone
|
The Shure Beta 98A is a
precision-engineered compact, high-output miniature condenser
microphone for professional sound reinforcement and studio
recording. An extremely uniform cardioid polar pattern provides
excellent gain-before-feedback and off-axis rejection of unwanted
noise.
Both Beta 98A configurations feature high sound pressure level
capability (SPL). Beta 98AD/C includes A98D drum mount with
flexible gooseneck that makes it an essential, accurate choice for
toms, snares, and percussion. Beta 98A/C is recommended for a
variety of acoustic or amplified instruments including drums,
piano, reed, wind, and strings.
