Shure BETA 58A Dynamic Vocal MicrophoneThe Beta 58A is a high-Output supercardioid Dynamic Vocal Microphone

Key Features

• 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 off-axis sound
• Neodymium magnet for high signal-to-noise 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

• 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.
• Adjustable, Stand Adapter: Slip-in microphone mounting, unbreakable, adjustable through 180 degrees with standard 5/8"-27 thread, black finish.
