Everything this camera needs, matched by our specialists. Silarius picks first.
The Shure ADX2FD/B87A is a digital handheld wireless microphone transmitter compatible with Axient Digital series receivers. It is ShowLink-enabled for automatic interference avoidance and real-time remote control of parameters. The transmitter also features Frequency Diversity for seamless audio in even the most challenging RF environments.
The ADX2FD/B87A comes equipped with the Beta 87A supercardioid condenser capsule designed to withstand extreme sound pressure levels, while still delivering a remarkably smooth frequency response for vocal performers and presenters. The capsule features a supercardioid polar pattern that offers excellent rejection of off-axis background noise, helping to reduce feedback.
The transmitter operates in a single 146 MHz ultrawide UHF bandwidth. It provides up to 9 hours of operation on an SB920 rechargeable battery, with a transmission range up to 330' and a selectable 2/10/50mW RF output power.
With a durable, moisture-resistant, lightweight aluminum case, the ADX2FD/B87A transmitter delivers pristine audio quality, AES 256-bit encryption for secure transmission, and advanced rechargeability options, making it ideal for high-profile, sound-reinforcement 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) & 2 x 2/10/20mW (Frequency Diversity mode).
- 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 Beta 87A supercardioid condenser capsule handles SPL levels up to 140 dB and offers a smooth frequency response with a gradual presence rise and controlled proximity effect tailored for vocals.
- The interchangeable capsule design allows you to replace the Beta 87A capsule with a Shure capsule that’s ideal for your application and simply screw it onto the transmitter—including KSM9, KSM8, SM58, VP68, Beta 87C capsules, and more.
- 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.
- Two transmission modes: Standard for optimal coverage and High-Density for maximum system channel count and robust coverage.
- Operates for up to 9 hours in single-carrier mode at 10mW on an SB920 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.
