The Shure ADX2/B87A Wireless Microphone Transmitter Beta 87Ais 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 ADX2/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 2/10/40mW RF output power.

With a durable, moisture-resistant, lightweight aluminum case, the ADX2/B87A transmitter delivers pristine audio quality, mission-critical RF performance, AES 256-bit encryption for secure transmission, and advanced rechargeability options, making it ideal for high-profile, sound-reinforcement applications.

• 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.
• 2/10/40mW 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.

• Operates for up to 9 hours on an SB920 rechargeable lithium-ion battery.
• 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.

Q: 6. This is one mic per receiver right? The receiver can't have 2 mics simultaneously, correct?

A: The receiver in this QLXD system can only receive 1 transmitter at a time. For a dual channel receiver system of similar quality, you'd want this ULXD2D receiver, BH #SHULXD4DH50 with two separately purchased transmitters BH #SHLXD2B58H50.

Q: 7. Can I use this with phantom power

A: While this unit doesn't require phantom power, the unit can be used with phantom power on.

Q: 8. isn this compatable with qlx?

A: Yes, the Shure RPW120 Beta 87A Supercardioid Condenser Capsule for Handheld Transmitter is compatible for use with wireless handheld transmitters from Shure's QLX product line.

Q: 9. Can I stack multiple of these units? Thanks!

A: Shure does not recommend stacking multiple BLX88 and BLX4 receivers on top of each other since the antennas are built into the casing. You may want to consider the BLX4R receivers instead since this model has external antennas and multiple receivers can be easily rackmounted and stacked on top of each other without blocking the signal from going to the antennas.

Q: 10. Can I use it for my glxd4 z2 beta 87a?

A: The microphone capsules on the GLXD2 Handheld transmitters are fully integrated (hard-wired into the transmitter) so if you are looking to switch out your current mic capsule for another, this is not possible in the GLXD Series. Your only option in that case would be to purchase another GLXD2 transmitter all together, which can in turn be used with your existing GLXD4 receiver. If you might be looking to replace the capsule because you believe it may be defective, then it is best to seek repair under warranty from Shure (additional details regarding warranty coverage and procedure for return can be found on a href= http://Shure.com target= _blank Shure.com/a).
