The Shure Beta 58A is a high-output supercardioid dynamic wired vocal microphone designed for professional sound reinforcement and project studio recording. It has become a leading choice among vocalists and touring professionals worldwide. The Beta 58A maintains a true supercardioid pattern throughout its frequency range. The Beta 58A has a shaped frequency response that is ideal for close-up vocals. The superb performance of this microphone is not affected by rough handling because of its rugged construction, proven shock mount system, and hardened steel mesh grille.
Frequency response tailored for vocals, with brightened midrange and bass rolloff to control proximity effect
Uniform supercardioid pattern for high gain before feedback and superior rejection of offaxis sound
Neodymium magnet for high signaltonoise output
Hardened steel mesh grille that resists wear and abuse
Advanced pneumatic shock mount system that minimizes transmission of mechanical noise and vibration
Minimally effected by varying load impedance
Legendary Shure quality and reliability
Type: Dynamic (moving coil)
Frequency Response: 50 to 16,000 Hz
Polar Pattern: Supercardioid, rotationally symmetrical about microphone axis, uniform with frequency.
Output Level (at 1,000 Hz) Open Circuit Voltage: -51.5 dBV/Pa* (2.6 mV) *1 Pa = 94 dB SPL
Impedance: Rated impedance is 150 ohms (290 ohms actual) for connection to microphone inputs rated low Z Phasing. Positive pressure on diaphragm produces positive voltage on pin 2 with respect to pin 3.
Case: Silver blue enamel-painted die cast metal with hardened, matte-finished, spherical steel mesh grille.
