QLX-D: Shure's Digital DNA Inspired by the ULX-D Series
Building on the digital wireless transmission technology of the ULX-D series, the QLX-D range is designed to offer professional-level quality and reliability while remaining easy to deploy daily. It is suitable for both demanding fixed installations (rooms, auditoriums, houses of worship, businesses) and live performance uses where RF stability and sound consistency are essential. In practice, QLX-D positions itself as a versatile "pro" solution: performance, security, and control without complicating setup.
For Stage, Events, and Installations Where Reliability is Key
A QLX-D system is particularly relevant when managing dense RF environments, multiplying wireless links, and maintaining consistent audio quality from one microphone to another. On stage, it secures performances with stable digital transmission and efficient frequency management. In installations, it facilitates operation (monitoring, network control) and meets the needs of venues where confidentiality is important (meetings, conferences, institutions), thanks to integrated encryption.
