Boya BY-BM3031 Shotgun Microphone

Precise, Professional Audio

The BY-BM3031 is a directional microphone with a super-cardioid pickup pattern.  It is an ideal choice when you need to filter out distracting or ambient noise with your subject at a distance, or for pinpoint precise capture up close.  This type mic is a favourite for on-camera work, and the suite of pro level features offered by the BY-BM3031 easily makes it the best all-around mic in our lineup.

3-Level Gain Control

The PAD switch allows you to set your baseline audio levels to 0, +20dB, or -10dB, so it can adjust to the requirements of your scene.

High Pass Filter

The high pass filter (80 Hz) can be toggled on to remove low frequency hum and rumble from your audio.

Audio Monitoring

If your camera does not support audio monitoring, there is headphone jack built right into the mic that will allow you to monitor the baseline audio at any of the three base gain settings.

Integrated Anti-Shock Mount

Prevents sounds that are transferred through your camera body from reaching your audio.

Durable, Lightweight Construction

The BY-BM3031 is made from high quality ABS.

Wind Screens Included

Comes with the standard foam wind screen, as well as the "dead cat" wind screen for improved wind mitigation.
