Compact, Sturdy, and Lightweight

Built with an aluminum-alloy housing, the BY-BM6040 offers ruggedness while remaining compact and lightweight.

Cardioid Polar Pattern

The BY-BM6040’s cardioid polar pattern delivers responsiveness in front of the mic, maximum rejection at the rear, and moderate attenuation at the sides, making it well suited for recording indoors in rooms with low ceilings or capturing multiple subjects when shooting outdoors.

Voice-Tailored Tone

With a built-in 150 Hz high-pass filter and a 90 Hz to 20 kHz frequency response, the microphone offers tonality that’s tailored for natural-sounding voice reproduction while reducing difficult bass issues such as rumble.

Phantom Powered

The balanced XLR 3-pin output and support for 12 to 48 VDC phantom powering make the BY-BM6040 a great match for professional camcorders, field recorders, and many handheld audio recorders. A short XLR cable is included for easy connectivity.

Strong Output Signal

The mic boasts a high sensitivity of -30 dB, which allows it to produce strong output levels with less gain (and less noise) at your recording device.

Wind Protection

Use the included foam windscreen to control noise from light breezes or indoor turbulence from fans. Switch to the supplied furry windshield for enhanced wind noise reduction when recording outdoors.
