The Shure Beta 98AMP/C is a precision-engineered miniature cardioid condenser drum microphone featuring 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 SPL. Uniform cardioid polar pattern provides maximum gain-before-feedback and rejection of off-axis sound for smooth high-end response and control Precision-engineered design features integrated preamplifier and XLR connector to maximize setup efficiency while minimizing stage clutter Frequency response tailored for drums and percussion applications with a wide dynamic range for use in high SPL environments Flexible gooseneck for precise placement and easy adjustment Ships with A75M Universal Microphone mount with quick release, for versatile and secure instrument and/or stand mounting Furnished with snap-fit windscreen and zipper pouch Type: Electret Condenser Polar Pattern: Cardioid Frequency Response: 20 Hz to 20 kHz Output Impedance: 150 Ohms Sensitivity (at 1 kHz, open circuit voltage): -50.0 dBV/Pa (2.5 mV) Maximum SPL (1 kHz at 1% THD): 2500 Ohm load: 157.5 dB 1000 Ohm load: 153 dB Signal-to-Noise Ratio: 63 dB Dynamic Range (at 1 kHz): 2500 Ohm load: 126.5 dB 1000 Ohm load: 122.0 dB Clipping Level (1 kHz at 0.25% THD): 2500 Ohm load: 12.5 dBV 1000 Ohm load: 7.5 dBV Self-Noise (typical, equivalent SPL, A-weighted): 31 dB SPL Common Mode Rejection (10 Hz to 100 kHz): > 60 dB Polarity: Positive pressure on diaphragm produces positive voltage on pin 2 with respect to pin 3 Power requirements: 11-52 V DC phantom power (IEC-61938), 5.5 mA Weight: Net: 130 g (4.6 oz.)
