The NTG1's full frequency response, low noise and audio transparency make it an ideal film, video, and voice over microphone, while its low weight (105gm/3.7oz) makes it an ideal boom microphone. In addition to the native 20Hz-20kHz frequency response a selectable high-pass filter at 80Hz is available, which will prevent low end noise such as air conditioners and traffic from being recorded. The WSVM windshield is supplied to minimise light wind noise and plosives during recording.    Product Specifications Acoustic Principle Line Gradient Active Electronics JFET impedance convertor with bipolar output buffer Capsule 0.50 Polar Pattern Supercardioid Address Type End Frequency Range 20Hz - 20kHz Output Impedance 50O Maximum SPL 139dBSPL Maximum Output Level 6.9mV (@ 1kHz, 1% THD into 1KO load) Sensitivity -36.0dB re 1 Volt/Pascal (15.00mV @ 94 dB SPL) +/- 2 dB @ 1kHz Equivalent Noise Level (A-weighted) 18dBA Power Options +48V or +24V phantom power required from mixer or interface Weight 105.00g Dimensions 219.00mmH x 22.00mmW x 22.00mmD Output 3-pin XLR Output
