■Features:
- Successor model to the AT4073a. Enhanced RF protection against mobile phones, wireless intercoms, and radio waves. Significantly reduces noise and eliminates problems in harsh environments.
- Lightweight and compact, yet possesses narrow directivity from high to low frequencies, capturing target sounds with high clarity at short and medium distances.
- Ideal for mounting on video cameras and field recording.
- A special acoustic tube with a high-precision slit design and a transformerless circuit provide stable phase and a wide dynamic range.
- Featured is the newly developed ""Double Wave Diaphragm (PAT.P.),"" achieving class-leading front sensitivity and ultra-low noise levels.
- Lightweight, compact, and made of rugged aluminum for use in harsh environments.
- 80Hz, 12dB/octave offset effectively reduces wind noise. A high-pass filter and a -10dB pad switch are standard features, making them useful in any situation.

A newly designed windscreen that is resistant to wind noise is standard equipment.
