Shure ULXD2/K9HS-G57

The Shure ULXD2/K9HS-G57 is a professional digital handheld transmitter for ULX-D systems, featuring the KSM9HS dual-diaphragm condenser capsule with switchable hypercardioid and subcardioid polar patterns. This flexibility makes it ideal for high-end vocal performances in varied stage environments, offering precise audio capture with excellent gain before feedback.

It operates in the G57 frequency band (470"608 MHz) with an extended 138 MHz tuning range, and delivers 24-bit/48 kHz digital audio with AES-256 encryption for secure transmissions. The rugged, lightweight aluminum body includes a backlit LCD, IR sync, and 1/10/20 mW selectable RF output power.

The transmitter supports up to 11 hours on AA batteries or 8.5 hours with the optional SB900B rechargeable battery, compatible with Shure's intelligent charging systems. Its interchangeable capsule design allows use with other Shure capsules, offering flexible performance and professional-grade reliability.
