Designed for vocalists and presenters who require a microphone with a classic, high-energy sound and exceptional reliability, this model features a dynamic element known for its durability and ability to handle high sound pressure levels. The capsule delivers a pronounced presence peak in the upper midrange, which enhances vocal clarity and projection, helping performers cut through loud stage mixes with minimal feedback.

Built to withstand the rigors of touring, the transmitter features a durable metal body, a hardened steel grille, and an easy-to-read OLED display for monitoring battery life and RF status. It is powered by a high-capacity rechargeable lithium-ion battery designed for all-day use. The AD2/B58A represents a fusion of a proven, high-output dynamic microphone with state-of-the-art digital wireless intelligence, making it a powerful and dependable tool for the most demanding professional audio applications where consistent, clear, and controlled vocal reproduction is essential.
