For over 20 years, Beta Microphones have been the choice of top touring and recording professionals for reproduction of fine details in demanding acoustic environments. Each specialized model is precision-engineered with high output neodymium-equipped capsules for focused, accurate reproduction of the intended sound source. With superior construction, low handling noise and high gain before feedback, Beta redefines sensitivity and control for essential, expert sound reinforcement.
The Beta 87C premium vocal microphone delivers studio-grade performance and a smooth, extended high-end frequency response in a cardioid condenser design. It is basically the cardioid version of the Beta 87A, which has been a top choice for performers and audio engineers worldwide. The microphone adds warmth to the frequency response and creates an ideal environment for in ear personal monitoring. And its highly consistent cardioid pattern effectively rejects ambient noise arriving at the rear of the mircophone as well as sound bleed which makes this mic a great choice for live applications where personal monitors are being used.
