Condenser Cardioid Gooseneck Microphone
The RE90P-12 and RE90P-18 podium microphones are phantom-powered "back-electret" miniature condenser gooseneck microphones. The back-electret feature provides greater sensitivity, wider frequency response, and superior immunity from handling noise than a diaphragm-electret microphone.
Features:
• RF Shield provides superior RFI/GSM shielding
• Small size - unobtrusive for podium applications
• Frequency and cardioid polar response uniform across the range, for natural sound and high resistance to feedback
• Low, 200-Ohms output allows long cable runs
• Optional CPSM podium shock mount provides more than 15 dB of mechanical shock isolation at 200 Hz
Technical Specifications:
• Generation Element: Condenser, back electret
• Frequency Response: 100 Hz - 15.000 Hz
• Polar Pattern: Cardioid
• Sensitivity, Open Circuit Voltage, 1 kHz: 4.5mV/Pascal
• Dynamic Range: 102 dB SPL
