The Shure AD2/B87A is a digital handheld wireless microphone transmitter compatible with Axient Digital series receivers.

The AD2/B87A comes equipped with the Beta 87A 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 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/B87A 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.

Q: 7. Are you able to change the frequency on this wireless microphone system?

A: No the frequency is fixed at Band 7: 500.1 - 530.5MHz.

Q: 8. Why is it not compatible with the BLX?

A: BLX wireless series features a fully integrated capsule in its handheld transmitters. This means that the microphone capsule is hardwired into the transmitter handle which does not allow it to be removed to change capsule types. BLX and GLX-D are the only Shure wireless series with handheld transmitters like this. All other current series allow you to switch out the capsule and are compatible with this product.

Q: 9. 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).
