Shure AD2/N8CN-G57 Digital Handheld Wireless Microphone Transmitter with Nexadyne 8/C Cardioid Capsule (G57: 470 to 608 + 614 to 616 MHz, Nickel)

• Shure's Nexadyne Revonic system is an innovative dynamic microphone design that uses two matched dynamic transducers, working in conjunction, to provide more opportunity for both greater sound quality and the rejection of unwanted signal.
• Wiring the transducers out-of-phase cancels mechanical vibration, so self-noise is actively zeroed out. This makes traditional pneumatic shockmounts unnecessary, and allows the transducers to be optimized for acoustic performance.
• Vocal performers will experience natural and vivid clarity when performing—enabled by a cartridge design that optimizes signal output acoustically, producing more of the desired sound source and less environmental and handling noise.
• Engineers will receive stronger and clearer output, resulting in fewer EQ corrections that are often necessary with other mics to retain vocal clarity within the mix.
• The cardioid polar pattern provides focused, yet forgiving, audio capture centered on the performer in front of the mic—reducing bleed from other sources and on-stage monitors for clearer sound. 
• The interchangeable capsule design allows you to replace the Nexadyne 8/C capsule with a Shure capsule that’s ideal for your application and simply screw it onto the transmitter—including the Nexadyne 8/S (supercardioid), KSM8, SM58, Beta 58A, Beta 87A, and Beta 87C capsules.

• The AD2 quickly syncs with an Axient Digital wireless receiver at the touch of a button via infrared.
• 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.

• 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.
