Best Low Noise Interference

SYNCO Shotgun Microphone, Mic D30 Super Cardioid Condenser Microphone with Low Cut Filter, Real-time Monitoring System for DSLR/SLR, Smartphones, Camcorders, 3.5mm-Shotgun-Mic-for-Camera

【Natural Sound Rendering】 To achieve better off-axis noise suppression and frequency response, SYNCO Mic-D30 microphone employs a unique interference tube, combined with the acoustic design of slanting air vents. It optimizes the voice in intermediate frequency and enriches the audio details in low frequency, delivering clean, crisp and nature sound..
【Super High Sensitivity】 SYNCO D30 condenser mic provides a stepless analog gain dial, adjustable from -10dB to 15dB in the linear. You can subtly regulate the exact amount of gain increase or decrease as requested. Together with -24dB±2dB high sensitivity, Mic-D30 could capture very small acoustic wave to output clear, accurate sound..
【75Hz/150Hz Low Cut Filter】 With ultra low-noise electronics, Mic-D30 on-camera mic generates little inherent noise. 75Hz/150Hz optional low cut filter further purifies the sound, removing most of low frequency noise caused by airflow, shake, electrical current, or traffic. You can choose 75Hz or 150Hz low cut on the basis of environment and using demand..
