Shure just introduced the Axient Digital ADX3 plug-on transmitter, which the company says ADX3 transforms any XLR-terminated microphone into a portable Axient Digital ADX Series wireless microphone. Whether the microphone and ADX3 are in the hand of a reporter or suspended above an actor with a boom pole, ShowLink allows comprehensive, real-time control of all transmitter parameters, including interference avoidance, over a robust 2.4GHz diversity wireless connection — directly from the convenience of the receiver in a cart, bag, camera or truck.

Shure says the ADX3’s compatibility with Wireless Workbench supports efficient control and configuration, optimal spectrum management and frequency coordination. With real-time monitoring via the AD600 Spectrum Manager, the company says sound engineers can neutralize RF interference by manually switching the signal to a clear backup frequency, or by programming the system to do it automatically. Additionally, the ADX3 integrates with Axient Digital AD4D and AD4Q rack receivers as well as the Cinema Audio Society’s ADX5D Dual-Channel Portable Receiver.

Shure says ADX3 features a dust and moisture-resistant, rugged metal construction, as well as an OLED display with an easy-to-navigate menu. The device’s patented locking mechanism ensures a secure, wobble-free connection that readily interfaces with handheld and shotgun microphones, enhancing mobility during broadcasts and on TV/film sets.

The ADX3’s selectable modulation modes optimize performance for spectral efficiency, according to Shure. Users can select high density mode to dramatically increase their maximum system channel count or run ADX3 in standard mode for optimal, low latency coverage. Moreover, the ADX3 features automatic input staging and equips users with AES 256-bit encryption for secure transmission. With a line-of-sight operating range of 300 feet (100 meters), Shure says users can be “certain” they’ll experience maximum signal stability and transparent digital audio that sounds like a wire.

The ADX3 ships with two SB900 lithium-ion rechargeable batteries, with each battery providing up to six and a half hours of continuous use, precision metering and zero memory effect. The SB900 battery can be charged over a USB-C port. Alternatively, the transmitter can be powered externally via USB-C or by two AA batteries.

The new ADX3 is shipping now for $1399 (US). The package includes the plug-on transmitter, two SB900 batteries, USB-A to USB-C cable, belt clip/pouch and a zippered bag for storage.
