BETA58A Datasheet | Shure

DESCRIPTION The Shure BETA 58A is a high output supercardioid dynamic vocal microphone designed for professional sound reinforcement and project studio recording. It .. maintains a true supercardioid pattern throughout its frequency range. This ensures high gain before feedback, maximum isolation from other sound sources, and minimum off-axis tone coloration. 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. Typical applications for the BETA 58A include lead vocals, backup vocals and speech. Features S Frequency response tailored for vocals, with brightened midrange and bass rolloff to control proximity effect S Uniform supercardioid pattern for high gain before feedback and superior rejection of off-axis sound S Neodymium magnet for high signal-to-noise output S Hardened steel mesh grille that resists wear and abuse S Advanced pneumatic shock mount system that minimizes transmission of mechanical noise and vibration S Minimally affected by varying load impedance S Legendary Shure quality and reliability SPECIFICATIONS Type Dynamic (moving coil) Frequency Response 50 to 16,000 Hz (see Frequency Response, page 2) Polar Pattern Supercardioid, rotationally symmetrical about microphone axis, uniform with frequency (see Polar Patterns, page 2) Impedance Rated at 150 W (290 W actual) for connection to microphone inputs rated low Z Output Level (at 1,000 Hz) Open Circuit Voltage: - 71.5 d B- (0.27 m V) - 0 d B = 1 v/mbar Hum Pickup (at 60 Hz) Maximum 15.0 m V in 10 oe field Maximum 26.5 d B equivalent SPL per 1 moe Polarity 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 Connector Three-pin professional audio connector (male XLR) Swivel...
