Benefits

BY-V4U enables natural, multi-speaker recordings without tethering everyone to a single mic or device. The four-channel design ensures consistent dialogue capture across all participants, while the diverse output options let you plug into smartphones, laptops, cameras, or mixers with minimal setup. The system’s long-range capability, together with built-in noise cancellation, makes it suitable for on-location interviews, panels, and field reporting where ambient noise and movement can challenge audio quality. A rechargeable battery in the transmitters, USB-C charging on the receiver, and a charging case mean you can shoot longer between breaks, focusing on content rather than cables and power.
