Lark A1 Mini Duo system from Hollyland ensures mobile filming scenarios with your smartphone remain attractive and professional, all while maintaining a low profile for convenient on-the-go use. The included microphone transmitters supply 24-bit/48kHz sound, further bolstered by 3-level intelligent noise cancellation that keeps environmental disturbances, like wind and movement, entirely out of your mix. Likewise, onboard EQ, gain, and reverb controls allow you to dial in the perfect output for recording in any setting. Additionally, you get up to 54 hours of battery life to tackle even the most prolonged filming sessions with ease, not to mention extra charging capabilities via the included charging dock.
