Part of the ULX-D wireless series, the Shure ULXD4Q-GV houses 4 independent digital receivers in a rugged, single-rack unit with an internal 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. Two Ethernet ports support Dante digital audio, while RF cascade ports allow for antenna signal distribution to another receiver unit. Audio summing enables the receiver to function as a 4-channel mixer.

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.

Each receiver module has its own audio and RF meters, 60 dB of gain control, and XLR output. 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 ports also allow 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.

A: Yes, the RF in of the Sennheiser EW-DX EM 2 DANTE Two-Channel Digital Rackmount Receiver can be connected to the RF out (A and B) of the Sennheiser EW-DX EM 4 DANTE Four-Channel Digital Rackmount Receiver to utilize the 2 x 1/4-Wave Rod Antenna.

Q: 10. 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.
