Supercardioid Vocal Microphone
Roll over or click to zoom in
The Shure SM87A is a condenser microphone that offers you smooth frequency response specifically tailored for warm, rich, vocal reproduction.
Redesigned from the original SM87, the SM87A sports a slightly thicker handle for a more comfortable feel. In addition, the SM87A now includes the A25D break-resistant swivel adapter.
Tight polar pattern for high gain-before-feedback and rejection of unwanted sounds plus a 3-point shockmount that minimizes stand and handling noise. Runs on phantom power.
Features
Smooth frequency response with gradual presence rise Highly consistent supercardioid polar pattern provides superior gain-before-feedback Electronic low-frequency roll-off compensates for proximity effect Wide dynamic range (117 dB) and low distortion characteristics | | Very low susceptibility to RFI and electromagnetic hum Advanced cartridge shock-mount system absorbs mechanical shocks and reduces handling noise Built-in pop filter reduces undesirable wind and breath sounds Legendary Shure quality and reliability |
