Audio-Technica ATV-SG1 Camera-Mount Shotgun Microphone

The Audio-Technica ATV-SG1 shotgun microphone is designed for content creators, videographers, and audio professionals who demand precise, directional sound capture with enhanced control. Featuring a line + gradient polar pattern, this microphone focuses on audio directly in front of the capsule while minimizing unwanted ambient noise, making it ideal for interviews, video production, and on-location recording. Its compact yet robust design allows for seamless integration with cameras and portable recording setups.

Equipped with a high-performance fixed-charge back plate, permanently polarized condenser element, the ATV-SG1 delivers clear and detailed audio across a wide frequency range. The microphone includes a built-in adjustable gain control with a wide 37 dB range, allowing users to fine-tune input levels for different recording environments. A low-frequency roll-off filter at 160 Hz helps reduce handling noise and environmental rumble, ensuring cleaner recordings in both indoor and outdoor settings.

The ATV-SG1 also features a rechargeable lithium-ion battery for extended operation, providing up to 24 hours of use on a single charge. With headphone monitoring capability, users can monitor audio in real time, while the external input terminal allows for additional audio sources to be mixed directly into the signal. Designed for flexibility and reliability, this microphone is an all-in-one solution for capturing professional-quality sound with convenience and precision.
