Description
The Shure AD2/KSM9HSB digital handheld wireless microphone transmitter is engineered for professional live sound environments where precision, clarity, and reliability are critical. Built for seamless integration with Axient Digital wireless systems, this transmitter delivers exceptional RF stability and pristine audio performance for high-profile productions, concerts, and broadcast applications.
Equipped with the premium KSM9HS dual-diaphragm condenser capsule, the AD2TA/K9HSB offers switchable hypercardioid and subcardioid polar patterns. This flexibility allows engineers to adapt quickly to different stage conditions, ensuring optimal vocal capture, enhanced gain before feedback, and consistent tonal clarity. The capsule’s advanced design captures fine vocal nuances while maintaining excellent off-axis rejection.
Operating across a wide 470 to 616 MHz frequency range, the transmitter provides reliable RF performance with selectable output power levels to balance range and channel density. With AES 256-bit encryption, it ensures secure audio transmission, making it ideal for corporate, government, and broadcast environments requiring data protection.
The rugged aluminum housing is designed for durability and resistance to demanding touring conditions, while intuitive controls, an LCD interface, and IR sync simplify setup and operation. Flexible power options, including AA batteries or optional rechargeable lithium-ion packs, provide dependable performance for extended events.
