Shure SM87A Condenser Microphone
  • Sale
  • Regular price $232.50

The Shure SM87A microphone is a professional-quality, handheld condenser microphone for use in sound reinforcement, broadcasting, and studio recording installations. Its supercardioid polar pattern provides greater rejection of unwanted sound sources, making it ideal for miking individual instruments in a multi-microphone setting or for miking single sources in a reverberant or noisy environment. An integral three-stage wind and pop filter protects against wind and breath noise. Its built-in shock mount reduces stand and handling noise.

Cartridge Type
