Shure ADX2FD/K11B=-G57 ADX2FD/K11B Handheld Transmitter

The ADX2FD/K11B features a KSM11B condenser capsule with a cardioid polar pattern, ensuring focused audio capture on talent while minimizing background noise. Its aluminum and steel grille provides protection and includes a 3-layer pop filter to reduce breath and plosive noises. The built-in shock mount minimizes handling noise during live performances, resulting in clearer vocals. The deep cardioid pattern offers solid gain before feedback, with minimal off-axis coloration, providing a warm, full sound. Operating within a single 146 MHz ultrawide UHF bandwidth, the transmitter offers up to 9 hours of operation using an SB920A rechargeable battery. It boasts a transmission range of up to 330' and selectable 2/10/50mW RF output power. Encased in a durable, moisture-resistant, lightweight aluminum case, the ADX2FD/K11B transmitter ensures pristine audio quality, AES 256-bit encryption for secure transmission, and advanced rechargeability options, making it perfect for high-profile sound-reinforcement applications.

Frequency Diversity for Mission-Critical Applications
  • Frequency Diversity enables simultaneous transmission on two independent frequencies to ensure seamless, uninterrupted audio.
  • Single-carrier mode is available if Frequency Diversity is not required.
  • Switchable RF Power Levels: 2/10/50mW (single-carrier mode) and 2 x 2/10/20mW (Frequency Diversity mode).
ShowLink Enabled for Interference Avoidance & Parameter Control
  • 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.
Interchangeable Design with KSM11B Capsule
  • The KSM11B is a proprietary wireless condenser microphone capsule utilizing a 3/4" gold diaphragm and premium electronics for exceptional dynamic range and transient response.
  • The capsule features a highly consistent, deep cardioid polar pattern that reduces off-axis phase distortion for pristinely focused vocal reproduction to provide a rich and full low-frequency response, linear and transparent midrange, and natural high-end detail.
  • The dent-resistant, three-stage "pop" protection grille reduces plosives, wind, and other breath noise.
  • The interchangeable capsule design allows you to replace the KSM11B capsule with a Shure capsule that’s ideal for your application and simply screw it onto the transmitter—including KSM9, KSM8, SM58, Beta 58A, 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.
  • The power button conveniently doubles as a mute switch, while preserving the RF lock.
  • Frequency and power lockout functions prevent accidental or unauthorized changes during events.
  • A backlit LCD with an 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.
  • The offset function lets you balance mic levels when assigning multiple transmitters to a single receiver slot. Adjustment range: -12 to +21 dB.
  • Two transmission modes: Standard for optimal coverage and high density for maximum system channel count and robust coverage.
Convenient Power Management Options
  • Operates for up to 9 hours in single-carrier mode at 10mW on the included SB920A rechargeable lithium-ion battery.
  • Runs up to 6.5 hours in Frequency Diversity mode at 10mW x 10mW and up to 5 hours in single-carrier, high-power mode at 50mW.
  • 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.
