The AD2/KSM9B is outfitted with the KSM9 condenser capsule, renowned for capturing intricate sonic details and delivering exceptional vocal precision for elite live shows. The versatile KSM9 capsule presents two switchable polar patterns: the cardioid, known for its warm, full sound with efficient gain before feedback and limited off-axis distortion, and the supercardioid, perfect for situations with significant ambient noise or proximity of multiple performers.

Running on a 146 MHz ultrawide UHF bandwidth, the transmitter boasts selectable RF output powers and can reach up to 330'. Its operation lasts up to 8 hours on two AA batteries and 9 hours using the separately available SB900A lithium-ion battery.

Encased in a durable, moisture-resistant, lightweight aluminum, the AD2/KSM9B ensures top-tier audio, robust RF performance, and secure AES 256-bit encryption, making it perfect for high-stakes audio scenarios.

The KSM9 capsule's distinct features include dual 3/4” gold-layered Mylar diaphragms for stable frequency response, a Class-A, transparent transformerless preamplifier, and an inbuilt three-stage grille that mitigates plosive and breath noises. Its adaptable design lets you swap out the KSM9 for other Shure capsules—be it KSM8, SM58, Beta 58A, and more—to fit your needs.
