audio technica / ATM57a

This compact shotgun microphone measures just 279mm long and features a two-way power supply, making it suitable for any environment. Its 14mm diaphragm and refined slit design provide stable driving force, achieving a wide dynamic range and sharp directivity down to the low frequencies despite its compact size. It captures the target sound with high clarity when recording at short to medium distances, improving the quality of audio recordings for ENG applications and other applications.

- This compact shotgun microphone, measuring just 279mm in length and powered by a two-way power system, is the successor to the globally popular ATM57, a compact microphone suitable for any environment.

- The larger φ14mm diaphragm and refined slit design provide stable driving force, achieving a wide dynamic range and sharp directivity down to the low frequencies despite its compact size. It captures the target sound with high clarity when recording at short and medium distances, improving the quality of audio recordings for ENG applications and other uses.

- Two-way power supply system that automatically supports one AA battery or 11-52V DC phantom power.

- Includes an 80Hz, 12dB/octave high-pass filter as standard to effectively reduce wind noise.

- Includes a newly designed windscreen as standard to resist wind noise.

- Enhanced RF protection against mobile phones, wireless intercoms, and radio waves. Significantly reduces noise, eliminating problems in adverse environments.
