The Shure QLXD4 Wireless Receiver 902-928 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 X52: 902 to 928 MHz UHF band with a 26 MHz tuning range and 1040 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 12 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. Can this receiver be as a IFB to monitor audio?

A: Yes, the Sony URX-P40 Camera-Mount Wireless Receiver does have a 3.5mm headphone jack which can be used to monitor audio, so it could be used for an IFB application.

Q: 2. Will the receiver transmit static when the mics are turned off?

A: Whether a receiver creates noise while unpaired to its correlating transmitters is not a specification that manufacturers make known. In theory, the receiver in the Nady DW-22 HTHT Digital Wireless Microphone System should not present any extra noise when not paired to the microphone transmitters. However, as this device operates on open channels, it is susceptible to RF activity in the surrounding area, which could manifest as audible static noise.

Q: 3. How does this receiver compare to the Sennheiser EK 500 G4 Diversity Receiver Freq.Range Aw+ 470-558 MHz?

A: This receiver is designed for rack mount or table top applications. This allows the receiver to be ac powered from a wall outlet versus the need for batteries. As well, this unit has dual bnc antennas which can be attached to antenna distribution, useful when using a large amount of wireless in a venue. This unit is really meant for live sound or studio applications where the receivers will be stationary and in a rack. The EK500 is designed for portability.

Q: 4. The lapel mic on this unit stopped working. What other microphones would work with the transmitters of this unit?

A: You may consider the Azden EX-503 Lavalier Microphone, BH #AZEX503.

Q: 5. What is the body length including the antennas?

A: The Sony URX-P40 Camera-Mount Wireless Receiver has a specified height of 70mm or 2 7/8 inches without antennas. The antennas can add up to 5 inches of height, but their lengths vary depending on the frequency range chosen. Lower frequencies mean longer antennas.

Q: 6. how to make it receive?

A: In order for the wireless receiver to work, you will need to use a compatible transmitter with a microphone that operates on the same frequency band such as the Samson AH9 Wireless Transmitter with Fitness Headset Microphone - K: 470 to 494 MHz (B&H # SASW9QTCEK). The Samson AirLine 99m AH9 Wireless UHF Fitness Headset System - K: 470 to 494 MHz (B&H # SAW9A9SQEK) is the complete wireless system that includes the receiver and transmitter with a microphone.

Q: 7. Will this receiver work with the Sennheiser SK 500 G4 Bodypack Transmitter Freq.Range Aw+, 470-558 MHz?

A: Yes, it will work with the SK500G4 AW+.

Q: 8. Does this work with the ew 100 g3 body pack?

A: Yes, the EM 300-500 G4 receiver is compatible with G3 series transmitters.

Q: 9. Can you confirm the channels/frequencies? I need Ch D15/D16 (915.30 and 916.80).

A: Since the Nady Dual Channel Digital Handheld/Lapel/Headset Bodypack Wireless System is available by special order only, you can place the order by phone or contact us through live chat and specify the frequencies that you need so we can order it for you.

Q: 10. Can you use 2 of these units with one body pack transmitter. Use case would be put one receiver on camera for monitoring and one receiver into audio recorder as a way of having redundancy in recordings.

A: Yes, two Sony URX-P40 Camera-Mount Wireless Receivers can be used with a single transmitter, as long as both the transmitter and the receivers are set to the same wireless channel.
