The Beta 87C premium vocal microphone delivers studio-grade performance and a smooth, extended high-end frequency response in a cardioid condenser design. The microphone adds warmth to the frequency response and creates an ideal environment for in ear personal monitoring. And its highly consistent cardioid pattern offers excellent rear rejection.

Features:
 • Smooth, wide frequency response with slight presence rise
 • Uniform cardioid polar pattern for maximum isolation
 • Minimum off-axis tone coloration
 • Low-frequency roll-off compensates for proximity effect
 • Three-stage pop filter minimizes breath pop and noise
 • Break-resistant stand adapter
