The BY-V4 is particularly valuable for productions requiring clean ISO tracks for each speaker while maintaining minimal setup complexity.For larger productions, the system can be expanded with additional BY-V4 units (up to 16 channels total) through BOYA’s multi-system synchronization protocol. The included lavalier mics feature upgraded moisture-resistant capsules specifically designed for extended wear in demanding environments.
