The Shure QLXD4 Wireless Receiver V50 174-216 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 V50: 174 to 216 MHz VHF band with a 42 MHz tuning range and 1680 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 30 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.

• 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. I was told by another dealer that i cannot use a ULXD2 transmitter with a QLXD4 receiver, does anyone know if this is really true. cause under compatible TX's it says you can?

A: Yes, but both devices must have the same operating frequency band, such as G50. Group and Channel settings within the frequency band are the same for ULX-D and QLX-D. The Group and Channel number for each device have to be set manually, as the InfraRed sync will not work.

Q: 2. I'm buying the version with two handheld mics. Can I replace one or both mics with a lavalier mic at a later date?

A: There are not lavalier mics and bodypacks to purchase additionally for this system. The dual lavalier wireless system that is similar to this is the Pyle Pro PDWM2145 VHF Dual-Frequency Wireless System with 2 Lavalier and 2 Headset Microphones, BH #PYPDWM2145.

Q: 3. Do this Shure ULXD4Q come with 4 handheld wireless mics?

A: No. This is just the receiver by itself. You would purchase the 4 handheld transmitters separately, such as B&H # SHULXD2S5G50.

Q: 4. What are the dimensions of the receiver?

A: It's not tiny... I have one at home that I use with a DDJ WEGO2 and its around 7 x 4 x 1.5 inches.

Q: 5. Is the power supply 220v compatible?

A: Yes, the Shure QLXD4 Digital Wireless Receiver (G50: 470 to 534 MHz) BH #SHQLXD4G50 offers a 100 to 240 VAC, 50 / 60 Hz at 150 mA with a North American AC outlet plug.

Q: 6. Does this "open box" item include power supply, rackmount hardware, and antennas?

A: Yes, the Open Box version of the Shure QLXD4 Receiver (Listed separately from the New version and marked as such) comes with the power supply, rackmount hardware, and antennas.

Q: 7. This mics system works with the Pyle Pro Mini Blue Series Stereo 240W Power Amplifier?

A: These mics will work with this system only.

Q: 8. how many handheld mics can the 2CH version support?

A: Wireless receivers can accommodate one transmitter per channel; the two channel receiver can connect to two, and the four channel version can connect to four.

Q: 9. Does this unit require an antenna management system?

A: No, in fact if you notice each of the antennas has an output just below the inputs. This unit basically behaves like an antenna distribution system.

Q: 10. Have anyone tried to used them for Lectrosonics, ZAXCOM or WISYCOM receivers? How well does it work?

A: The Shure UA860SWB Passive Omnidirectional Antenna is designed specifically for use with the Shure SLX, ULX, UC, UHF, and UHF-R Wireless Receivers and covers the frequency range of 470 to 1100 MHz. We have not tested the antenna with wireless receivers from other manufacturers like Lectrosonics, Zaxcom, or Wisycom to be able to confirm compatibility.
