The Beta 58A� is a high-output superrdioid dynamic vol microphone for professional sound reinforcement and project studio recording. It has become a leading choice among volists and touring professionals worldwide.
The Beta 58A maintains a true superrdioid pattern throughout its frequency range. This insures high gain before feback, imum isolation from other sound sources, and minimum off-axis tone coloration. The Beta 58A has a shap frequency response that is ideal for oseup vols. The superb performance of this microphone is not fect by rough handling beuse of its r construction, proven shock mount system, and harden steel mesh grille.
Features
Frequency response tailor for vols, with brighten midrange and bass rolloff to control proximity effect
Uniform superrdioid pattern for high gain before feback and superior rejection of offaxis sound
Neodymium magnet for high signaltonoise output
Harden steel mesh grille that resists wear and abuse
Advanc pneumatic shock mount system that minimizes transmission of mechanil noise and vibration
Minimally effect by varying load impance
Legendary Shure quality and reliability
Specifitions
Spec Sheet (PDF) 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 Superrdioid, rotationally symmetril 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
Impance Rat impance is 150 ohms (290 ohms actual) for contion to microphone inputs rat low Z Phasing. Positive pressure on diaphragm produces positive voltage on pin 2 with respect to pin 3.
