The Shure ADX3 is a digital wireless plug-on microphone transmitter compatible with Axient Digital series receivers. It is ShowLink-enabled for automatic interference avoidance and real-time remote control of parameters. The ADX3 features a secure, twist-lock XLR connector and supplies 12 or 48V phantom power, allowing you to use any handheld or shotgun XLR microphone with the Axient ADX digital wireless system.
The transmitter operates in a single 146 MHz UHF bandwidth with selectable 2/10/35mW RF output power and a transmission range up to 330'. A special HD (high density) mode provides a dramatic increase in channel count when you're running numerous mics at the same time. The transmitter provides up to 6.5 hours of operation on a Shure SB900B rechargeable lithium-ion battery (included) or 5 hours on two AA batteries. A USB-C port is supplied for recharging and powering and a USB-C to USB-A cable, pouch with belt clip, and zippered storage bag are included.
With a durable, moisture-resistant, lightweight aluminum housing, the ADX3 transmitter delivers pristine audio quality and RF performance, AES 256-bit encryption for secure transmission, and advanced rechargeability options, making it ideal for high-profile sound-reinforcement applications.
