The SM58 Vocal Dynamic Microphone

A legendary mainstay of live performances, the SM58 is the mic that set the world standard. Boasting a classic look and world-renowned engineering, the SM58 is a durable, versatile mic that handles vocals with clarity and precision. It features a uniform cardioid polar pattern that faithfully reproduces your vocals so that they sound their best. An integrated pneumatic shock mount absorbs handling noise, so your sound doesn’t get lost in vibration. Meanwhile, the iconic spherical mesh grille and the mic’s built-in pop filter protect your audio from wind and plosives. This ruggedly-built mic is designed specifically to handle the rigors of touring and travel, so you can take it anywhere with you and perform on the go with confidence. Also included with the SM58 is a break-resistant swivel stand adapter and a storage bag to protect it from dust or other debris while in storage.

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).
