Shure has released a firmware update for its Axient Digital PSM in-ear monitoring platform, introducing a new transmission mode and workflow updates aimed at improving reliability and simplifying RF deployment.
The update adds Single Carrier (SC) Narrowband, a new digital transmission option designed to provide a more familiar operating model for engineers transitioning from analogue IEM systems to digital workflows. According to Shure, the mode is intended to reduce setup complexity while maintaining the low latency and spectrum efficiency of the existing platform.
SC Narrowband is designed to behave similarly to traditional narrowband in-ear monitoring systems while improving stability in more difficult RF conditions. The mode is aimed at productions where RF coordination time is limited or where reflective stage environments can create reliability challenges.
Nick Wood, associate vice president of marketing and product management at Shure, said the update was shaped directly by feedback from touring, broadcast and live event users.

While Axient Digital PSM already supports multi-channel wideband, narrowband and analogue FM operation, the addition of SC Narrowband gives engineers another deployment option depending on the scale and complexity of the production.
The firmware release also updates CueMode workflows. Engineers can now preview CueMode entries before applying them, while the system now supports multiple transmission modes within the same workflow. Shure says the changes are intended to reduce friction when managing mixed production environments and large-scale monitor setups.
The firmware update is available now through ShureCloud and the Shure Update Utility.
