Capture Professional Two-Person Audio Simultaneously
The BOYA BY-M1DM is the essential, professional-grade solution for capturing clear, broadcast-quality audio from two subjects at once, using only a single input device. This microphone system is purpose-built for content creators, journalists, podcasters, and filmmakers who frequently conduct interviews or record dialogue with two people.
Featuring two high-quality omnidirectional condenser capsules, the BY-M1DM ensures natural and intelligible sound capture from all directions. This design prevents volume drop-offs, even if speakers move or turn their heads during recording, making it ideal for dynamic dialogue.
Extended Range and Universal Compatibility
The dual lavalier microphones are separated by approximately 2.8 meters (9.2 feet) and connected to a central power pack, which offers a generous total cable length of 4 meters (13 feet) to the recording device. This extended length provides the necessary distance for comfortable, professional interview setups.
The compact power pack simplifies connectivity with a mode switch to toggle between Camera mode (for DSLRs, camcorders, etc., requiring battery power) and OFF/Smartphone mode (utilizing plug-in power from phones and PCs). This ensures the BY-M1DM is compatible with virtually every recording device in your kit.
Clean Audio Output for Post-Production
With a high Signal-to-Noise Ratio (74dB), the BY-M1DM delivers crisp, clean audio that minimizes unwanted background noise. Since each microphone routes its audio to a discrete stereo channel on your recorder, you retain maximum control, allowing you to easily balance and adjust individual levels during the editing process for a perfectly mixed final product.
