Beta 98AMP Miniature Cardioid Drum Microphone |
|
|
Product Code:
527B Microphone |
The Shure Beta
98AMP is a precision-engineered miniature cardioid condenser
microphone for professional sound reinforcement and studio
recording. Features an integrated XLR preamplifier with a
flexible gooseneck and the A75M Universal Microphone Mount for
accurate placement in any configuration of toms, snares, or
percussion. An extremely uniform cardioid polar pattern provides
excellent gain-before-feedback, off-axis rejection of unwanted
noise, and high maximum sound pressure level (SPL). |

[1] 1 Pa=94 dB SPL
[2] THD of microphone preamplifier when applied input signal level is equivalent
to cartridge output at specified SPL
[3] S/N ratio is the difference between 94 dB SPL and equivalent SPL of self
noise, A-weighted
[4] All specifications measured with a 48 Vdc phantom power supply. The
microphone operates at lower voltages, but with slightly decreased headroom and
sensitivity.
