The Beta 52A features a modified supercardioid pattern throughout its frequency range to insure high gain-before-feedback and excellent rejection of unwanted sound. A built in dynamic locking stand adapter with an integral XLR connector simplifies installation, particularly if the microphone is to be placed inside a kick drum. The stand adapter keeps the microphone position fixed and resists slipping, even when subjected to sharp blows and strong vibrations. A hardened steel mesh grille protects the Beta 52A from the abuse and wear associated with touring.Cartridge Type Dynamic (moving coil)Frequency Response 20 to 10,000 HzPolar Pattern SupercardioidOutput Impedance 150 ΩSensitivity (at 1kHz, open circuit voltage) −64 dBV/Pa (0.6 mV) 1 Pascal=94 dB SPL Maximum SPL (1 kHz at 1% THD, 1kΩ load) 174 dBPolarity Positive pressure on diaphragm produces positive voltage on pin 2 with respect to pin 3 Weight Net: 0.605 kg (1.35 lbs)Connector Three-pin professional audio (XLR), male Case 134 dB (159 dB, -25 Pad)
