Professional MEASUREMENT Microphone featuring a back electret-condenser element with omnidirectional polar pattern. Offers a frequency response of 20Hz~20kHz and sensitivity of -63dB ± 3dB (0dB=1V/Pa@1kHz). With 250Ω ±30% impedance and signal-to-noise ratio exceeding 65dB, this precision instrument handles maximum SPL of 105dB at 1kHz with ≤1% THD. Powered by standard phantom power (9V~52V DC) through a 3-pin mini XLR connector, the microphone features durable aluminum and copper construction. Compact cylindrical design measures ø7×183.7mm (L), making it suitable for precision acoustic measurements requiring accurate omnidirectional response.
