• 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.

• 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.

• 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.
