BOYA BY-M1DM Dual Lavalier Mic for Smartphones, DSLR, and Audio Recorders

Product Overview The BOYA BY-M1DM is a dual-mic lavalier system designed for recording two subjects simultaneously. It features two independent omnidirectional microphones connected to a single 3.5mm TRRS connector, making it an essential tool for interviews, podcasts, and vlogging. With its integrated power pack, it switches seamlessly between "Camera" mode (active power for DSLRs/PCs) and "Smartphone" mode (passive mode for mobile devices).

Key Features

• Dual-Mic Recording: Capture two distinct sound sources at once through a single input jack.

• Wide Compatibility: Works with smartphones, DSLRs, camcorders, and audio recorders using the switchable power module.

• Omnidirectional Pickup: Provides a consistent frequency response and 360-degree sound capture for natural-sounding dialogue.

• Long Reach: The 4-meter (13ft) cable provides ample slack for comfortable movement during sit-down interviews.

• Low Handling Noise: Engineered to minimize clothing friction and background interference.

Prototyping and Engineering Tips from Robogears

• Smart Device Usage: When using with modern smartphones that lack a 3.5mm jack, you will need a high-quality Lightning or USB-C to 3.5mm adapter.

• Battery Management: Always remember to switch the mic to "OFF/Smartphone" mode when not in use. Leaving it in "Camera" mode will drain the LR44 battery even if it isn't plugged in.

• Placement Strategy: Clip the mics roughly 6–8 inches below the subject's chin. This distance prevents "plosives" (popping sounds) while maintaining a high signal-to-noise ratio.

• Outdoor Audio: If recording in windy environments, we recommend upgrading to a "dead-cat" furry windscreen for even better noise rejection than the included foam windscreens.
