Beschrijving

Uniform half-cardioid polar pattern for maximum gain-before-feedback and rejection of off-axis sound | Precision-engineered low-profile design features integrated preamplifier and XLR connector to maximize setup efficiency while minimizing stage clutter | Frequency response tailored for kick drum/low frequency applications with a wide dynamic range for use in high SPL environments | Two-position contour switch to maximize attack and clarity depending on application:select the flat response setting for natural sound in most applications or the “low-mid scoop” setting for a strong low frequency “punch” with plenty of higher frequency at | Requires no external mounting or accessories for ease of use and storage | Furnished with zipper pouch | Connector : Three-pin professional audio (XLR) male balanced | Impedance : 146 Ohms | Impedance : 146 ohm | Power Requirements : 11-52 Vdc phantom power 5.6 mA | Sensitivity : -48.50 dBV | Regulatory Compliance : CE EMC | Polarity : Positive pressure on diaphragm produces positive voltage on pin 2 with respect to pin 3 | DC Voltage : 52 Volts | Maximum SPL (Sound Pressure Level) : 155 dB | Product Weight : 0.47 kg | Common Mode Rejection (20 Hz to 20 kHz) : > 55 dB | Clipping Level (20Hz-20 kHz at 1% THD) : 1000 Ohm load | THD of microphone preamplifier when applied input signal is equivalent to cartridge output at specified SPL | Self Noise (typical equivalent SPL A-weighted) : 29.5 dB (SPL-A ) | Frequency Contour Switch : 7 dB of attenuation centered at 400 kHz | Minimum Frequency Response (Bandwidth) : 20 Hz | Minimum Frequency Response (Bandwidth) : 0.02 kHz | Maximum Frequency Response (Bandwidth) : 20000 Hz | Maximum Frequency Response (Bandwidth) : 20 kHz | Dynamic Range : 125.50 dB | Signal to Noise Ratio : 64.50 dB
