The Shure QLXD2/B87A is a digital handheld wireless microphone transmitter compatible with QLX-D receivers. It 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 QLXD2/B87A operates on a 26 MHz UHF tuning range with 1040 selectable frequencies available. It provides up to 9 hours of operation on two AA batteries, with a transmission range up to 330' and a selectable 1/10mW RF power output.

With a rugged, yet lightweight aluminum housing, the QLXD2/B87A transmitter delivers pristine audio quality and RF performance, as well as AES 256-bit encryption for secure transmission and advanced rechargeability options. It is well suited for sound reinforcement applications in medium-sized venues and houses of worship as well as A/V installations in conference, educational, and corporate facilities.

A: Powering the Hollyland Mars 4K Wireless Video Transmission System, the Canon 5D Mark IV, and the Hollyland Mars M1 Enhanced 5.5" Wireless Transceiver Monitor will render you approximately 1-2 hours of operation with the SmallRig VB99 Pro Mini V-Mount Battery being the source of power for all the items.

Q: 9. I know it says line of sight but does it have any range when there is something blocking it such as a wall or people?

A: No, all wireless transmitters are measured only via line of sight, as walls tend to vary greatly in terms of construction material, thickness, and internal obstructions, so no such measurement can be accurately represented/recreated. Expect signal strength to decrease when going through walls.

Q: 10. Does it fit Shure SM-57s and SM-58s?

A: The diameter on the A53M will not support the SM57 or SM58 microphones. You will need the A55M. Please see the following link: a href= http://bhpho.to/1D1kldz target= _blank http://bhpho.to/1D1kldz/a
