The black Shure AD2/KSM9HSB is a digital handheld wireless microphone transmitter compatible with Axient Digital series receivers.
The AD2/KSM9HSB comes equipped with a dual-diaphragm KSM9HS condenser capsule that captures sonic nuances with superior detail, delivering precise vocal reproduction for high-end live performances. The KSM9HS capsule offers two switchable polar patterns to provide FOH engineers with more choices in dealing with varying environments or the microphone techniques of different performers. The hypercardioid pattern offers excellent off-axis rejection and extended gain before feedback, making it an ideal choice in loud environments. The subcardioid pattern provides a wide coverage angle with subtle off axis-rejection, resulting in a natural sound and minimized proximity effect.
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/KSM9HSB 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.
