The Shure QLXD4 Digital Wireless Receiver G50 470-534 MHzis 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.

Related Questions and Answers

Q: 1. is there a difference between buying this and two single channel digital wireless receivers ?. apart from saving some money

A: There is no difference apart from saving money and space.

Q: 2. Will this be able to pair with a ULX transmitter in the g50 band?

A: No, the Shure SLXD5 is only able to connect to SLXD receivers on the G58 band.

Q: 3. Does this only work in US or any country that allows the selected frequency range (A: 470 to 636 MHz) ?

A: The Shure AD4D-US Axient Digital Two-Channel Wireless Receiver (A: 470 to 636 MHz) should work anywhere that allows the stated frequency range. You may want to consider the location's power requirements/output specifications when connecting to this unit.

Q: 4. how many mics can each channel have? or is it 1 mic per channel?

A: The Shure ULXD4D Dual-Channel Digital Wireless Receiver (G50: 470 to 534 MHz) has two separate channels which can each be used with a separate transmitter/microphone. Two transmitters/microphones can be used simultaneously with the ULXD4D Receiver.

Q: 5. How many ULXD4D receivers that you can link without the D.A

A: you can only connect two systems without Distribution

Q: 6. Can the QLXD1 G50 beltpack be programmed to the L50 frequencies, or the receiver programmed to the G50 frequencies?

A: They cannot they are two different models and they have different connectors. The QLXD1 is a TA4 and the L50 is a 3 pin lemo.

Q: 7. What exactly is the difference between this kit BH #SHSLXD4DH55K (B&H Kit) and BH #SHSLXD14DH55 ?

A: The Shure SLXD14D Dual-Channel Digital Wireless Bodypack System Kit with No Mics (H55: 514 to 558 MHz) (B&H # SHSLXD4DH55K) is effectively the same as the Shure SLXD14D Dual-Channel Digital Wireless Bodypack System with No Mics (H55: 514 to 558 MHz) (B&H # SHSLXD14DH55), however the B&H kit is a bundle of 2x Individual SLXD1 bodypacks and 1x SLXD14D receiver, while the non-B&H Kit version is a single item. As the B&H Kit is multiple items, it allows us to get a better bundle price for the same equipment.

Q: 8. Please advice which SD cards work with the PXW-X180 Sony video camera

A: Any current class 10 SD would work. For the work this camera is supposed to do, I would recomend this kind of card, Sony 64GB Ultra-High Durability Professional SDXC UHS-I Memory Card (Class 10) B&H # SOPSD64GB.

Q: 9. My receiver is a J50 unit. With the J50A be the correct transmitter?

A: Yes, you can use the QLXD2/B87A-J50A transmitter with your QLX-D-J50 or ULX-D-J50 receiver. The FCC recently changed regulations for the frequency band above 616 MHz. This range is no longer available for use by wireless microphones and is now designated for use with broadband. Due to these changes, Shure has discontinued the J50 band (572 to 636 MHz) and replaced it with the J50A band (572 to 608 + 614 to 616 MHz), which covers much of the same bandwidth as J50. Older QLX-D and ULX-D components that operate on the J50 band can be used with newer components operating on the J50A band.

Q: 10. 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.
