About this item
The Shure AD2/B58 is a digital handheld wireless microphone transmitter compatible with Axient Digital series receivers.
Interchangeable Design with Beta 58A Capsule
The Beta 58A features a neodymium magnet for high signal-to-noise output.
The hardened steel-mesh grille resists wear and abuse.
The interchangeable capsule design allows you to replace the Beta 58A capsule with a Shure capsule that’s ideal for your application and simply screw it onto the transmitter—including KSM9, KSM8, SM58, Beta 87A, Beta 87C capsules, and more.
User-Friendly Features in a Rugged Housing
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.
2/10/35mW 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.
Convenient Power Management Options
Optional SB900A 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.
