Shure Beta 58A Dynamic Microphone

The Beta 58A maintains a true supercardioid pattern throughout its frequency range. As a result the mic can achieve 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.

Shure Beta 58A Specifications

Type

Dynamic (moving coil)

Frequency Response

50 to 16,000 Hz

NOTE: The curve above shows on-axis response at a distance of 2 feet from a uniform sound source. Your response may vary, depending on microphone position.

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.
