The black Shure AD2/KSM8B Wireless Microphone Transmitter 470-616 MHzis a digital handheld wireless microphone transmitter compatible with Axient Digital series receivers.

The AD2/KSM8B comes equipped with a KSM8 dual-diaphragm dynamic capsule that minimizes proximity effect, delivering a consistent sound even when the distance between the mic and the sound source varies. The cardioid polar pattern provides a clean, richly detailed signal with reduced feedback, great for speech and vocals in live venues.

The transmitter operates in a single 146 MHz ultrawide UHF bandwidth with selectable 2/10/35mW RF output power and a transmission range up to 330'. It provides up to 8 hours of operation on two AA batteries and up to 9 hours with an SB900A lithium-ion rechargeable battery (available separately).

With a durable, moisture-resistant, lightweight aluminum case, the AD2/KSM8B transmitter delivers pristine audio quality and RF performance, AES 256-bit encryption for secure transmission, and advanced rechargeability options, making it ideal for high-profile, sound-reinforcement applications.
