From the manufacturer's website:
- Equipped with a newly developed, high-sensitivity microphone unit with independent cardioid and bidirectional polar patterns. Three selectable modes—MS Direct, LR Wide, and LR Narrow—enable it to capture target sounds in noisy environments, or capture stereo bass and ambience in indoor and outdoor sports recordings.

- A special acoustic tube with a high-precision slit design and a transformerless circuit provide stable phase and a wide dynamic range.

- Overall length 380mm, weight 142g. Made of lightweight, durable aluminum for use in harsh environments such as on-camera or boom-mounted for outdoor recording.

- Comes standard with an 80Hz, 12dB/octave low-cut switch that effectively reduces wind noise.

- Enhanced RF protection against radio waves from mobile phones and wireless intercoms. Reduces noise and eliminates problems in poor working environments.
