Part of the ULX-D wireless series, the Shure ULXD4-GV houses a single digital receiver in a rugged half-rack unit with an external power supply. This GV version of the receiver features always-on AES-256 encryption and is designed for government and high-level executive applications where sensitive audio information may be transmitted.

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.

Related Questions and Answers

Q: 1. Does it have Wi-Fi

A: No, this AV receiver does not have wifi. The Pioneer Elite VSX-LX104 7.2-Channel Network A/V Receiver, BH #PIVSXLX104 would be a good option with wifi.

Q: 2. Any way to find an adapter to allow this to be powered by AC?

A: There is no known battery eliminator/AC adapter option for use with the Shure P3RA Wireless Bodypack Receiver for PSM300 System. An alternative powering solution would be found in the Shure SB900B Rechargeable Lithium-Ion Battery for Bodypack Transmitters/Receivers (BH #SHSB900B): https://bhpho.to/3JPx5sT

Q: 3. How is this receiver different than the DCR822 other than the slot-in size capability?

A: The Lectrosonics DSR Two-Channel Digital Slot Receiver and the Lectrosonics DCR822 Compact Dual-Channel Digital Wireless Receiver are incredibly similar units, and both models are compatible with the same transmitters. The only differences are within secondary characteristics like the type of panel used for the screen (OLED for the DCR822 / IPS for the DSR). Additionally, the DCR822 has onboard recording capabilities via microSDHC and can be powered with AA batteries or DC power. The DSR uses DC power only.

Q: 4. Can this antenna be use with two UA844+SWB connected to four QLXD4, and four ULXS4 receivers?

A: Yes, these antennas can be used with the UA844+ so long as the frequency range of the antennas cover the frequencies used on the systems.

Q: 5. Anyone try this with a 1080p 120hz input?

A: This receiver works perfectly passing through 1080p, 120Hz, and higher.

Q: 6. Compatible with UwMic9?
