Bundled together by B&H, the Shure QLXD24/B87A Kit is a rackmount digital wireless handheld microphone system that provides performers, presenters, and broadcasters with professional-quality audio, reliable RF performance, and secure AES 256-bit encryption. Rugged and easy-to-use, it is ideal for sound-reinforcement applications in medium-sized venues and houses of worship as well as A/V installations in conference, educational, and corporate facilities.
The system operates in the UHF band to transmit pristine 24-bit/48 kHz digital audio with clarity, accurate low end, and crisp transient response. It utilizes Digital Predictive Switching Diversity to protect the transmission from interference and deliver solid RF signal stability without audio artifacts. You can run up to 60 mic channels at the same location.
The QLXD24/B87A includes the QLXD2 handheld transmitter featuring an interchangeable capsule design and equipped with a Beta 87A condenser capsule. The supercardioid pickup pattern focuses on the voice, helping to reduce feedback on loud stages. The lightweight transmitter provides up to 9 hours of operation on two AA batteries, with selectable 1/10mW RF power and a transmission range up to 330'.
The receiver features audio and RF meters, 60 dB of gain control, and both mic/line XLR and 1/4" instrument outputs. A large LCD screen and intuitive controls let you quickly make adjustments, even in low-light situations. Additional features include automatic frequency scanning, IR sync, and internal limiting to prevent clipping.
The Ethernet port allows multiple receivers to be easily networked together for simplified frequency coordination and deployment via Shure's Wireless Workbench (WWB) software.
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 64 MHz UHF tuning range with 2560 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.
- The unit delivers clear, reliable 24-bit/48 kHz digital audio.
- 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 SM58, KSM8, SM87A, Beta 58A, Beta 87C, KSM9 capsules, and more.
- The unit quickly syncs with a wireless receiver via infrared at the touch of a button.
- The adjustable input sensitivity on the transmitter accommodates mic levels ranging from booming voices to quiet speech.
- 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, and RF output.
- 1/10mW selectable RF output power allows you to increase either the transmitter's range or the number of mics operating simultaneously.
- Operates for up to 9 hours on two AA batteries.
- Optional Shure SB900A lithium-ion rechargeable battery pack offers intelligent power management with over 10 hours of battery life, precision metering in hours and minutes, and zero memory effect.
- External charging contacts allow for docked battery charging with the SBC200 dual-docking charger (available separately).
- The networkable SBC220 charger (available separately) allows for remote power monitoring via Shure’s Wireless Workbench software.
The Shure QLXD4 is a digital half-rack wireless receiver housed in a rugged, full-metal chassis and compatible with QLXD1 bodypack and QLXD2 handheld transmitters. It provides instructors, presenters, and broadcasters with professional-quality audio, reliable RF performance, and secure AES 256-bit encryption. Easy to set up and operate, it is ideal for use in TV broadcast or sound-reinforcement applications in medium-sized venues and houses of worship, as well as A/V installations in conference, educational, and corporate facilities.
The QLXD4 operates in the G50: 470 to 534 MHz UHF band with a 64 MHz tuning range and 2560 selectable frequencies. It delivers pristine 24-bit/48 kHz digital audio with clarity, accurate low end, and crisp transient response. The receiver utilizes Digital Predictive Switching Diversity to protect the transmission from interference and provide solid RF signal stability without audio artifacts. You can run up to 60 mic channels at the same location.
The unit features audio and RF meters, 60 dB of gain control, and both mic/line XLR and 1/4" instrument outputs. A large LCD screen and intuitive controls let you quickly make adjustments, even in low-light situations. Additional features include automatic frequency scanning, IR sync, and internal limiting to prevent clipping.
The Ethernet port allows multiple receivers to be easily networked together for simplified frequency coordination and deployment via Shure's Wireless Workbench (WWB) software.
- The receiver works with a wide selection of Shure mics and transmitter types including the QLXD1 bodypack and QLXD2 handheld transmitters that provide complete mobility for presenters/performers.
- Digital Predictive Switching Diversity uses a microprocessor to switch antennas before dropouts occur.
- Two detachable 1/2 wave dipole antennas are included.
- 256-bit AES encryption offers unbreachable privacy by using a unique, randomized encryption key generated every time encryption is enabled.
- Low latency makes the system ideal for meetings that require live sound reinforcement.
- The QLXD4's scanning function automatically finds, prioritizes, and deploys the cleanest frequencies to transmitters via IR sync.
- The receiver offers up to 60 dB of adjustable gain with an internal limiter that automatically engages to prevent digital clipping of your audio.
- Intuitive front-panel controls with audio and RF LED meters as well as a peak indicator, allow for quick visual checks.
- Ethernet networking enables real-time, precision monitoring and control of your system as well as automatic frequency coordination across multiple receivers, using Wireless Workbench software (WWB) for Mac/Windows.
- The receiver is compatible with external controllers such as AMX and Creston.
- Remote Control: Make adjustments from anywhere in the venue from your iPad/iPhone via the ShurePlus Channels Mobile App for iOS devices.
- Adding UA874 active antennas or PA805 passive antennas increases the range of your system and offers increased protection against interference.
- The UA844+SWB antenna distribution system (available separately) lets you stretch the power of your antenna pairs, giving you more on-air channels in less setup time.
