Make Any Microphone Wireless


Do you have a wired mic that absolutely has to be onstage but doesn’t work with your wireless system? Worry no more — the Shure AD3 plug-on transmitter is here to save the day! This transmitter plugs right into your mic’s output, making it wireless in an instant. The AD3 uses Shure’s Axient wireless technology and AES 256-bit encryption for maximum performance and reliability. For mission-critical applications like televised live performances and secure government installations, there aren’t many products that can compete with Axient regarding sound quality and sheer reliability. Shure’s patent-pending locking XLR connector ensures the transmitter stays in place with wobble-free performance. With a pair of AA batteries, the AD3 can achieve up to eight hours of continuous use. Like all Shure products, the AD3 plug-on transmitter is built to withstand a lifetime of use and abuse onstage.

World-class sound quality and transmission security

We’ve used a lot of wireless technology over the years at Sweetwater, and the sound quality of Shure’s Axient digital wireless is second to none. Wireless transmission latency is an ultra-low 2ms — best in its class. Thanks to AES 256-bit encryption, transmissions remain secure, making Axient the perfect choice for government facilities and other sensitive installations.

Frequency diversity for maximum reliability

Axient wireless stands out in the wireless realm with its frequency diversity capability. It essentially allows transmission of a single source on two independent radio frequencies. Axient continuously analyzes the signal quality and uses both frequencies for optimized performance. You’ll experience no interruptions, dropouts, or audio artifacts caused by direct RF interference.

Advanced interference detection and avoidance

Axient’s ability to detect and avoid interference is second to none. Signal interference can come from a wide range of sources, not just radio and telecom signals. The AD3 plug-on transmitter is equipped with Shure’s most sensitive detection circuitry to sense signal degradation. You have your choice of automatic avoidance, or you can manually select a new frequency if you choose. When using the Axient Spectrum Manager, backup frequencies are constantly monitored, ranked, and automatically deployed in the event of signal interference.
