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.

• Single-channel receiver operates in the G50: 470 to 534 MHz UHF band
• 64 MHz tuning range lets you run up to 60 channels at the same location in Standard mode or 90 channels in High-Density mode
• Digital Predictive Switching Diversity uses a microprocessor to switch antennas before dropouts occur
• Comes with two remoteable 1/2 wave dipole antennas
• 256-bit AES encryption offers unbreachable privacy—uses unique, randomized encryption key generated every time encryption is enabled
• Interference detection and alerts provide instant confirmation on both the receiver LCD and WWB software when interference is present
• 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

Networked Control

• Ethernet networking enables real-time, precision monitoring and control of your system, as well as automatic frequency coordination across multiple receivers, using Wireless Workbench, SystemOn, and Axient Spectrum Manager software
• 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. 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: 2. Could this be used as an input and output of an audio interface to a macbook pro for streaming?

A: This would connect to the input of your interface and work to transmit the microphone audio while streaming. There would be no way to monitor wirelessy.

Q: 3. Does this set work without a mixer?

A: The wireless mic system can be plugged directly into a powered speaker, via the MIC level XLR output or the LINE level 1/4-inch output.

Q: 4. Will this work with any device that takes XLR? Such as an older sound board?

A: Yes, the Sennheiser EW 135P G4 Camera-Mount Wireless Cardioid Handheld Microphone System can be connected to any XLR audio input when using the included Sennheiser CL-100 1/8"-Male Mini Jack to XLR-Male Connector Cable (B&H # SECL100).

Q: 5. Could this system be used as an audio mic for a battery powered speaker (everse 8)via an car input cable

A: You can use a DC power cable from the receiver of the Nady DW-22 or the Electro-Voice R300, connected to the DC Power Out port on the Electro-Voice Everse 8 speaker.

Q: 6. Am I reading correctly that this system can support both mics transmitting at the same time/same channel?

A: This system features a dual receiver, so both mics can operate at the same time, but they have separate outputs, which would go into two channels of a mixer. The Samson Concert 288 All-In-One Dual-Channel Wireless System (H-Band, 470 to 518 MHz), BH #SASWC288ALLH does offer a mixed output, if you require a single output to your mixer or portable speaker.

Q: 7. Can you remove the antennas?

A: No, the antennas in the rear of the DW-22 receiver are not removable, but they can be adjusted for tilt and angle.

Q: 8. What are the choices of frequencies. Already have 915.30 aand 916.80?

A: The entire DW-22 series are 900mHz: https://bhpho.to/3gpl5Qh

Q: 9. Do these come with the appropriate cables to feed out to a mixer?

A: It does not. You will need 2 mic cables.

Q: 10. does this system include a case for protection and transport?

A: No, it does not.
