The black Shure AD2/N8CB is a digital handheld wireless microphone transmitter compatible with Axient Digital series receivers. The AD2/N8CB comes equipped with a Nexadyne 8/C dynamic cardioid capsule featuring an innovative Revonic dual-transducer design that uses two separate, but interdependent sets of diaphragms, voice coils, and magnets. This unique technology gives this dynamic mic a condenser-like clarity with a crisp, yet natural high-end and plenty of detail—allowing vocalists to worry less about mic technique and instead focus on delivering powerful performances. The cardioid polar pattern reduces off-axis pick up, for less bleed from other sources and fewer feedback issues.

The transmitter operates in an ultrawide 140 MHz ultrawide UHF bandwidth with selectable 2/10/35mW RF output power and a transmission range up to 330'. It provides up to 8 hours of operation on two AA batteries and up to 9 hours with an SB900A lithium-ion rechargeable battery (available separately). With a durable, moisture-resistant, lightweight aluminum case, the AD2/N8CB transmitter delivers pristine audio quality and RF performance, AES 256-bit encryption for secure transmission, and advanced rechargeability options, making it ideal for high-profile, sound-reinforcement applications.

Interchangeable Design with Nexadyne 8/C Cardioid Revonic Capsule
  • 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.
User-Friendly Features in a Rugged Housing
  • 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.
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.

Too easy for my Lab
Color: Blue
My lab figured this out in 30 seconds. I was hoping it would be a bit more challenging for him. Thankfully, it is challenging enough for my bunny!
