Learn how to set up the Boya BY-MM1 shotgun microphone on your camera for clear video audio. Includes step-by-step instructions, common mistakes, and pro tips for vloggers.

Quick Answer

Mount the Boya BY-MM1 on your camera's hot shoe, connect the TRS cable to your camera's mic input, turn on the mic with the on/off switch, and set your camera's audio input to manual at a low level to avoid distortion.

Why the BY-MM1’s Cardioid Pattern Matters

The BY-MM1 uses a cardioid condenser pickup pattern, which captures sound primarily from the front and rejects noise from the sides and rear. This is ideal for vlogging and interviews where you want to isolate the subject's voice and minimize ambient room echo or wind noise.

Limitation: No Volume Control on the Mic

The BY-MM1 does not have its own gain knob, so you must adjust audio levels through your camera's menu. If your camera has only automatic audio gain, you may notice the mic pumping background noise. In that case, use a camera that supports manual audio level control or an external recorder.

Boya BY-MM1 Setup Steps

1. Mount the Microphone: Slide the BY-MM1's shoe mount into your camera's hot shoe. Tighten the thumbscrew until the mic is secure and level. Common mistake: Mounting the mic off-center, which can cause uneven stereo imaging if using two mics. Center it directly above the lens.
2. Connect the Audio Cable: Plug the supplied 3.5mm TRS cable into the mic's output jack and the other end into your camera's external mic input. For smartphones or computers, use the TRRS cable (included) instead. Checkpoint: Use the correct cable for your device. TRS for cameras, TRRS for phones/laptops. Wrong cable = no audio or buzzing.
3. Power On the Microphone: Slide the power switch on the side of the BY-MM1 to the ON position. A green LED indicates the mic is active. Common mistake: Forgetting to turn on the mic. The LED is small; check it before recording.
4. Set Camera Audio Levels: Enter your camera's audio menu and switch the input from auto to manual. Set the level to a low value (e.g., 1–3 out of 10) to avoid clipping. Speak at your normal volume and adjust upward if the meter stays below -12 dB. Checkpoint: If audio sounds distorted or has a hiss, the level is too high. Lower it and test again.
5. Monitor with Headphones: Plug headphones into your camera's headphone jack (if available) to monitor audio in real time. Listen for handling noise, wind, or clipping. Common mistake: Not monitoring leads to unusable audio discovered only in post. Always wear headphones during setup.
6. Use the Windscreen Outdoors: Attach the foam windscreen over the mic's capsule when recording outside. It reduces wind noise but does not eliminate heavy gusts. Checkpoint: For windy conditions, a furry deadcat windscreen (sold separately) is more effective than the included foam.
