The BOYA BY-M1DM Dual Omnidirectional Lavalier Microphone features two lav mics attached to a single 3.5mm TRRS connector, making it easy to record two people at the same time to your smartphone, DSLR/mirrorless camera, camcorder, recorder, computer, or similar device. Great for interviews, the mics feature forgiving, omnidirectional pickup patterns that help maintain consistent audio levels, even when the speaker turns away from the microphone. Each mic is routed to a discrete channel, allowing you to adjust the individual levels later in your editing software for just the right balance. The 74 dB signal-to-noise ratio helps cut down on noise and hiss for more professional-sounding recordings. Powered is supplied by your smartphone or by the included LR44 battery if you’re recording to a camera. Two foam windscreens and two lapel clips to attach the mics to clothing are also included, along with a carrying pouch.
