• ShowLink technology allows the ADX transmitter to execute an automatic, synchronized frequency change in a matter of milliseconds, ensuring clean, uninterrupted transmission, even in the most challenging RF environments.
• You can also make instantaneous remote adjustments to your ADX transmitter settings (RF output, gain, mute, and more) when it is difficult or impossible to access the transmitter.

• The interchangeable capsule design allows you to replace the SM58 capsule with a Shure capsule that’s ideal for your application and simply screw it onto the transmitter—including KSM9, KSM8, Beta 58A, Beta 87A, Beta 87C capsules, and more.

• The unit quickly syncs with a wireless receiver via infrared at the touch of a button.
• Automatic Gain adjusts the mic input level for you.
• 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.
• Offset function lets you balance mic levels when assigning multiple transmitters to a single receiver slot. Adjustment range: -12 to +21 dB.
• 2/10/40mW selectable RF output power allows you to increase either the transmitter's range or the number of mics operating simultaneously.
• Two transmission modes: Standard for optimal coverage and High-Density for maximum system channel count and robust coverage.

• Operates for up to 9 hours on an SB920 rechargeable lithium-ion battery.
• Rechargeable battery offers intelligent power management with precision metering in hours and minutes, and zero memory effect.
• External charging contacts allow for docked battery charging.
• SBC220 two-bay and SBC840 eight-bay networked chargers (both available separately) allow for remote power monitoring via Shure’s Wireless Workbench software.
