Shure ULXD2/KSM9 Digital Wireless Handheld Microphone Transmitter

With an interchangeable KSM9 microphone capsule, the ULXD2/KSM9 delivers uncompromising audio quality and RF performance, and AES 256-bit encryption for secure transmission. This transmitter is available in a variety of different frequencies.

Please Note: When purchasing separate wireless components, please match their frequency bands to ensure proper system operation.

The KSM9 Microphone Capsule

Capture the nuances and detail of your vocals with the KSM9 microphone capsule. Boasting a dual diaphragm design and switchable polar patterns (supercardioid and cardioid), the KSM9 has been designed specifically for stellar performance in live environments. It offers exceptional consistency across all frequencies, delivering more gain before feedback while simultaneously decreasing the proximity effect.

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).
