AT - Condenser Boundary Microphone Ashken

UniGuardTM RFI-shielding technology offers outstanding rejection of radio frequencyinterference(RFI). Superior off-axis rejection for maximum gain before feedback. Small-diameter UniPoint capsule near boundary eliminates phase distortion and delivers clear, high-output performance. Heavy die-cast case and non-silp silicon foam bottom pads minimize coupling of surface vibration to the microphone. Low-profile design with low-reflectance finish for minimum visibility. AT871UG has contained electronics eliminate need for external power module. The AT871UG requires 9V to 52V phantom power for operation only. AT871UG Specifications Element Fixed-charge back plate, permanently polarized condenser Polar Pattern Half-cardioid (cardioid in hemisphere above mounting surface) Frequency Response 30 ~ 20,000 Hz Open Circuit Sensitivity -34 dB(19.9mV) re 1V at 1Pa Impedance 200 Ω Maximum Input Sound Level 133 dB SPL (1KHz,THD 1%) Dynamic Range (Typical) 103 dB, 1 kHz at Max SPL Signal-To-N...
