The ATV-SG1 boasts a highly directional 100 mm acoustic tube to keep pickup focused on the sound source while blocking unwanted background noise. Like the 20 Series mics, the ATV-SG1 provides professional-quality sound for lifelike reproduction of the human voice and other sources. Key to this natural, high-resolution sound capture is the mic’s newly designed 14 mm large-diameter diaphragm, which exhibits high-sensitivity and low-noise characteristics for rich, detailed audio. In addition, the mic’s integrated shock mount dissipates unwanted handling noise from camera movement and vibrations, while Audio-Technica’s patented noise-immunity technology prevents the mic from picking up any annoying hum from nearby smartphones or other electronic devices.
