The ULXD2 Digital Handheld Transmitter

Providing enhanced mobility and flexibility—yet in a rugged construction for confident long-term use no matter what the application—the ULXD2 is a handheld wireless transmitter that is compatible with Shure’s ULX-D Digital Wireless Systems.

The ULXD2 proprietary Gain Ranging optimizes the system’s dynamic range for any input source, so you no longer need to adjust the transmitter. Use Transmitter Mute Mode to reassign controls to the On/Off switch, changing it into a Mute Switch so you can turn off audio without sacrificing RF channel presence. It also features frequency and power lockout, a backlit display for efficient navigation and settings control, and much more. In addition, the ULXD2 comes with integrated AES 256-bit encryption, ensuring secure transmission.  

This handheld transmitter features a durable, all-metal build, as well as external charging contacts for docked charging (with the SBC200 Dual Docking Charger, sold separately).
