Shure ULXD2/KSM11B Digital Handheld Wireless Microphone Transmitter with KSM11 Capsule (G57: 470 to 608 MHz)

The Shure ULXD2/KSM11B is a digital handheld wireless microphone transmitter compatible with ULX-D receivers. It comes equipped with a KSM11 condenser capsule, featuring a cardioid polar pattern with consistent off-axis rejection that focuses audio capture on the talent and picks up less background noise. The capsule offers an aluminum and steel grille that protects the mic and provides a 3-layer pop filter to help reduce breath and plosive noises. The built-in shockmount helps reduce handling noise during live performance for clearer vocals. The deep cardioid pattern offers solid gain before feedback, with minimal off-axis coloration, for a warm, full sound.

With rugged, yet lightweight aluminum housing, the ULXD2/KSM11B transmitter delivers pristine audio quality and RF performance, AES 256-bit encryption for secure transmission, and advanced rechargeability options for professional sound-reinforcement applications.

Clear, Accurate Audio with Interchangeable Capsule

The unit delivers clear, reliable 24-bit/48 kHz digital audio over its entire 330' range, great for live performances and presentations in music venues, houses of worship, and conference spaces.

The KSM11 is a proprietary wireless condenser microphone capsule utilizing a 3/4" gold diaphragm and premium electronics for exceptional dynamic range and transient response.

The capsule features a highly consistent, deep cardioid polar pattern that reduces off-axis phase distortion for pristinely focused vocal reproduction to provide rich and full low-frequency response, linear and transparent midrange, and natural high-end detail.

The dent-resistant, three-stage "pop" protection grille reduces plosives, wind, and other breath noise.

The interchangeable capsule design allows you to replace the KSM11B capsule with a Shure capsule that’s ideal for your application and simply screw it onto the transmitter—including the KSM9, KSM9HS, SM58, SM86, SM87A, Beta 58A, Beta 87A, Beta 87C capsules, and more.

User-Friendly Features in a Rugged Housing

The transmitter offers an ultrawide 138 MHz tuning range from 470 to 608 MHz, allowing you to use it across a wide geographical range with a compatible ULX-D receiver.

The unit quickly syncs with a wireless receiver via infrared at the touch of a button.

Shure Proprietary Gain Ranging automatically adjusts the mic input level, eliminating the need for transmitter gain adjustments.

The power button conveniently doubles as mute switch, while preserving RF lock.

Frequency and power lockout functions prevent accidental or unauthorized changes during events.

A backlit LCD with easy-to-navigate menu and controls lets you quickly access frequency, group, and channel settings, along with mute and lock status, RF output, and remaining battery life.

1/10/20mW selectable RF output power allows you to increase either the transmitter's range or the number of mics operating simultaneously.

Convenient Power Management Options

Operates for up to 11 hours on two AA batteries.

Optional Shure SB900B lithium-ion rechargeable battery pack offers intelligent power management with over 8 hours of battery life, precision metering in hours and minutes, and zero memory effect.

External charging contacts allow for docked battery charging with the SBC200 dual-docking charger (available separately).

The networkable SBC220 charger (available separately) allows for remote power monitoring via Shure’s Wireless Workbench software.
