Compatible with Axient® Digital Wireless Systems, the Shure AD2/KSM8 Handheld Transmitter is a wireless microphone transmitter that equips you with professional-caliber audio and enhanced RF performance—no matter what your application. Boasting a KSM8 Dualdyne™ microphone capsule, this transmitter is ideal for capturing vocals. Its design is characterized by a backlit LCD with an intuitive menu and controls as well as a low-profile, lockable power switch.

The AD2’s rugged metal construction allows it to take the punishment of the most demanding stages, while its black finish blends seamlessly into virtually any environment. It comes with a zippered bag, a brass adapter, a black swivel adapter, two AA alkaline batteries, and a battery contact cover.
