Large conference and convention installations come with unique wireless challenges. A campus-wide solution, ULX-D® Digital Wireless is secure, scalable, and durable. From managing diverse sound sources to protecting RF from smartphones and other stray signals, the intelligent system solves wireless problems of all sizes.

Coming in Fall 2025 - Expanded Frequency Bands for ULX-D

As announced in June 2025, ULX-D components will ship with expanded frequency bands for greater geographical coverage - up to 166 MHz wide (regionally dependent).

ULX-D components with expanded frequency bands, including ULXD1 bodypack transmitters, ULXD2 handheld microphone transmitters, ULXD4D Dual Receivers and ULXD4Q Quad Receivers will be shipping in Fall 2025, for use in more locations with fewer frequency variations to manage.

Break through with wireless scalability.
