ULXD4 Single-Channel Digital Wireless Receiver (G50: 470 to 534 MHz)

19,633 Points

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.
