Shure AD2/KSM8N Digital Handheld Wireless Microphone Transmitter

The Shure AD2/K8N=-G57 is a digital handheld wireless microphone transmitter that pairs the celebrated KSM8 dual-diaphragm dynamic capsule with the Axient Digital platform. It delivers clear, detailed sound that cuts through stage mixes and spoken-word venues alike. Performers and presenters who demand consistent vocal quality will appreciate its cardioid pickup pattern, which focuses on the source while holding off feedback and handling proximity effects with ease.

A wide 146 MHz tuning range lets engineers find open frequencies even in crowded RF environments, and selectable output levels at 2, 10, or 35 mW provide the headroom needed for everything from club stages to stadium setups. AES 256-bit encryption keeps the signal private for high-profile events, while real-time waveform monitoring through an Axient Digital receiver makes system management straightforward.

The transmitter runs up to eight hours on standard AA batteries, or up to nine hours when you switch to the optional SB900A rechargeable pack for greener, cost-effective operation. Its nickel-plated aluminum housing feels light in the hand yet stands up to moisture, road wear, and constant changeovers.

Whether you are mixing front-of-house for a touring act, coordinating microphones for a worship service, or outfitting a corporate stage, this transmitter fits naturally into demanding workflows and keeps vocalists, hosts, and speakers sounding their best.
