Shure has expanded its ULX-D line with the introduction of Dual and Quad Receivers. The ULXD4D (Dual) and ULXD4Q (Quad) come with an extensive set of additional features including High Density Mode, Bodypack Frequency Diversity and Dante digital audio networking.

Designed for high channel-count applications requiring a working range up to 30m, the High Density Mode allows operating up to 560 channels in 72MHz, respectively 63 channels in an 8MHz TV channel. High Density mode optimises the system’s output power and digital RF filtering to reduce its spectral footprint from 350kHz to 125kHz, with no loss of sound quality. This allows ULX-D systems to be tuned to frequencies that are closer together without interference.

The Bodypack Frequency Diversity safeguards against loss of audio signal caused by RF interference or by power loss in a transmitter. If the RF signal quality from one transmitter drops, the audio from the good channel is switched to both outputs within milliseconds to preserve the audio signal.

For networked audio applications, Dante provides uncompressed, multichannel, low-latency digital audio over a standard Ethernet cable.

‘The ULX-D Dual and Quad Receivers offer uncompromising audio quality, RF signal stability and efficiency, and advanced set-up features in one single rack unit,’ says Michael Suchanka, Senior Portfolio Planning Manager at Shure Europe. ‘Combined with the suite of features ULX-D offers, the new Dual and Quad Receivers bring a new level of performance to professional installed sound.’

Lightweight and compact, the 1U-high metal chassis houses two, respectively four independent receivers, each with their own audio and RF meters, gain control and XLR outputs that can be either direct or summed for flexible signal routing. Plus with RF cascade and two Ethernet ports, units can easily share the RF signal and be networked together for simplified frequency coordination and deployment.
