Shure SM87A Vocal Microphone

The Shure SM87A is a professional-quality, condenser microphone that features a smooth, tailored frequency response for use in sound reinforcement, broadcasting, and studio recording installations. It's supercardioid polar pattern provides increased rejection of unwanted sound sources, making it ideal for miking individual instruments in a multi-microphone setting or for miking single sources in reverberant or noisy environments. The SM87A has a built-in three-stage wind and pop filter that protects against wind and breath noise while its built-in shock mount reduces stand and handling noise.

Shure SM microphones have come to define the sound of live performance. Sound engineers have relied on SM products on stage and in concert halls for years. Remarkably reliable and consistent they are the standard house sound equipment for venues worldwide.

Applications: Lead Vocals, Backup Vocals.
