About Shure SM87A

The Shure SM87 now features a new design and has been renamed the SM87A. In response to user requests, Shure has redesigned this microphone by just slightly thickening the handle for a more comfortable feel. In addition, the SM87A now includes the A25D break-resistant swivel adapter.

A favorite choice of the world's top entertainers, the SM87A condenser microphone features a smooth frequency response that's specifically tailored for warm, rich, vocal reproduction.

The Shure Model SM87A 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.

The SM87A features a controlled low-frequency roll-off tailored for optimum performance when close-miking sound sources. An integral three-stage wind and pop filter protects against wind and breath noise. Its built-in shock mount reduces stand and handling noise. The SM87A operates on phantom power.
