Beta58A汇动态线麦克风

The Beta 58A is high-output supercardioid dynamic vocal microphone designed for professional sound reinforcement and project studio recording. It has become leading choice among vocalists and touring professionals worldwide. The Beta 58A maintains true supercardioid pattern throughout its frequency range. This insures high gain before feedback, maximum isolation from other sound sources, and minimum off-axis tone coloration. The Beta 58A has shaped frequency response that is ideal for close?Cup 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. Features Frequency response tailored for vocals, with brightened midrange and rolloff to control proximity effect Uniform supercardioid pattern for high gain before feedback and superior rejection of off?Caxis sound Neodymium magnet for high signal?Cto?Cnoise 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 BETA58A and reliability Specifications Spec Sheet (PDF) Type Dynamic (moving coil) Frequency Response 50 to 16,000 Hz NOTE: The curve above shows on-axis response at distance of 2 feet from 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. Dimensions See User Guide. Net Weight 278 grams (9.92 oz)
