Part of the ULX-D wireless series, the Shure ULXD4 houses a single digital receiver in a rugged half-rack unit with an external power supply.

The ULX-D Series simplifies the set up and management of large numbers of wireless systems. It is ideal for professional sound reinforcement applications in large live venues and houses of worship, as well as A/V installations in conference, educational, and corporate facilities. Compatible with a wide selection of Shure transmitters and mic capsules, it delivers pristine 24-bit/48 kHz digital audio, capturing every detail with clarity, accurate low end, and crisp transient response.

The ULX-D operates in the UHF band, utilizing Digital Predictive Switching Diversity to protect the transmission from interference, delivering rock-solid RF signal stability without audio artifacts. In Standard mode you can run up to 17 channels per 6 MHz TV channel, at a range up to 330'. Alternatively, the High-Density mode lets you run up to 47 channels per 6 MHz TV channel, at a maximum range of 98'. The system offers AES-256 encryption for security.

The unit features audio and RF meters, 60 dB of gain control, and both XLR and 1/4" 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, gain optimization to match any input source, 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 software. In addition, the Channels Mobile App enables you to control the system remotely from an iOS device.

• Compatible with external controllers such as AMX and Creston
• Crosssubnet control-enabled for management between multiple facilities or venues

Functionality

• Optimized scanning automatically finds, prioritizes, and deploys the cleanest frequencies to transmitters over IR sync
• Proprietary Gain Ranging optimizes system dynamic range for any input source, eliminating the need for transmitter gain adjustments
• Internal limiter automatically engages to prevent digital clipping of your audio
• Unit has an individual gain control, an XLR output with switchable mic/line level, and a 1/4 output 
• Quick visual check using audio and RF LED meters with peak indicators
• Intuitive front-panel controls with lockout feature and easily readable LCD with adjustable contrast
• Remote Control: Make adjustments anywhere in the venue via the Channels Mobile App for iOS devices
• Smart Power Management on Transmitters: Advanced SB900A lithium-ion rechargeable batteries with SBC chargers (both available separately) provide extended transmitter battery life over alkaline batteries, battery-life metering in hours and minutes (accurate to within 15 minutes), and detailed tracking of battery health status

Related Questions and Answers

Q: 1. What type of Digital Wireless Receiver compatible with Shure GLXD2/SM58 Digital Wireless Handheld Microphone Transmitter with SM58 Capsule (2.4 GHz)?

A: This handheld mic transmitter pairs with the Shure GLXD4 Digital Wireless Receiver (2.4 GHz), BH #SHGLXD4Z2 or the rack mountable Shure GLXD4R Advanced Digital Wireless Receiver (2.4 GHz), BH #SHGLXD4RZ2.

Q: 2. 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: 3. Can this hand held mic connect to J10 receiver?

A: Yes, the Shure BLX2/B58 Handheld Wireless Microphone Transmitter with Beta 58A Capsule (J11: 596 to 616 MHz) can be used with an existing J10 BLX receiver. The following link from Shure specifies overlapping compatible frequencies between the two ranges and provides further details: https://bit.ly/3s9zDLr

Q: 4. 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: 5. 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: 6. 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: 7. is the body of mic plastic or metal ?

A: Shure uses a Metal body casing for all of its QLXD receivers and transmitters.

Q: 8. Does the transmitter overheat from frequent use?

A: Temperature with use over time is not a commonly defined specification for wireless transmitters such as the Shure ULXD1 Digital Wireless Bodypack Transmitter with TA4M. However, increased temperatures with long periods of use is common for products in this category.

Q: 9. I have receiver DDT4T I looking for Handheld Transmitter . Do you think this one work with my receiver?

A: I am sorry - B&H has no reference for a DDT4T transmitter. The ULXD2 Handheld Transmitter with SM58 Microphone Capsule (G50) is designed for compatibility with Shure's ULX-D wireless systems only.

Q: 10. Will this transmitter work with the ULXP4 receiver?

A: No it is not. The Shure ULXD1 is a digital wireless bodypack transmitter compatible with ULX-D and QLX-D receivers only.
