Boya BY-M1DM Dual Lavalier Lapel MicrophoneTechnical Specifications & Overview The BOYA BY-M1DM is a dual-capsule universal omnidirectional lavalier microphone designed for two-person interviews, dialogues, podcasts, vlogs, live streaming, and broadcast recording. Featuring two discrete electret condenser mic capsules attached to a single 4-meter (13ft) cable with a 3.5mm TRRS gold-plated plug, it allows creators to record two subjects simultaneously into a single smartphone, DSLR/mirrorless camera, camcorder, audio recorder, or PC. Built with a dual-mode power pack switch ("Camera" vs. "OFF/Smartphone"), it draws power directly from smartphones and mobile devices when switched to "OFF/Smartphone" mode, or uses an included replaceable LR44 button cell battery when switched to "Camera" mode. The 4m integrated cable provides 2.8m (9.2ft) of separation between the two microphone heads for flexible subject placement.
