• The contoured form factor and lightweight Ultem PEI plastic construction offer both comfort and heat resistance.
• The gasketed membrane-style buttons, all sealed with an external rubber sheath, protect against sweat, spray, and moisture ingress.
• The recessed LEMO connector features an internal gasket that prevents sweat or rain from getting inside the bodypack, even with no microphone attached.
• The hermetically sealed OLED display is both airtight and waterproof.
• The internal antenna makes the bodypack much easier to hide and more comfortable to wear while eliminating another point of ingress.
• The SB910M battery slides firmly into place, eliminating the battery door and preventing any liquid from reaching the contacts.

• 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 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 internal adaptive antenna automatically optimizes its tuning characteristics by adapting the bodypack’s RF output when worn against the body.
• The power button conveniently doubles as mute switch, while preserving RF lock.
• Frequency and power lockout functions prevent accidental or unauthorized changes during events.
• The OLED display 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.
• 2/10/20mW 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.
• Detachable belt clip

• Operates for up to 7 hours at 10mW on an SB910M rechargeable lithium-ion battery.
• Rechargeable battery offers intelligent power management with precision metering in hours and minutes, and zero memory effect.
• SBM910M charging module and SBC840M eight-bay networked chargers (both available separately) allow for remote power monitoring via Shure's Wireless Workbench software.
