  • Norsonic NOR1225 Microphones/preamplifiers

    Experience the Norsonic NOR1225 Microphones/preamplifiers — engineered for precise, standards-compliant acoustic measurements. Overview All Norsonic microphones are Free-field types. A free field microphone is designed to measure the sound pressure in the sound field, compensating for the influence of the presence of the microphone in the sound field. In effect, the microphone measures the sound pressure as it existed before the microphone was introduced in the sound field, i.e. Free-field conditions. Applicable standard is IEC 61672 and the former IEC 60651. The free field microphone should be pointed towards the sound source at a 0° angle of incidence. Specifications Cartridge size: ½” inch Main standard: IEC 61672 Class 1 Polarisation voltage: 200 volt IEC 61094-4 Designation: WS2F Nominal sensitivity:50 mV/Pa Frequency response: ±1dB 5 Hz – 10kHz, ±3dB 3.15 Hz – 20kHz Maximum SPL (3% dist):146 dB 20µPa Self noise: 15 dB(A) Capacitance:18 pF Temperature coeff.
