Shure announced a firmware update for Axient Digital PSM, introducing new features designed to improve reliability, simplify setup, and address real-world challenges experienced by monitor engineers and production teams. The update introduces Single Carrier (SC) Narrowband, a new digital transmission option created to give users a more familiar and dependable starting point—particularly for engineers moving from traditional analog in-ear monitoring systems to digital. SC Narrowband delivers consistent performance without requiring complex RF coordination or advanced antenna setups, making it well suited for fast-paced productions and smaller or more challenging stages. This makes it particularly useful for performers working near reflective metal surfaces or in environments where setup time and RF planning are limited. Engineers can now choose the transmission approach that best fits each performer or area of the stage. Axient Digital PSM continues to support a mix of wideband, narrowband, and analog FM operation, allowing productions to combine different workflows and integrate existing equipment as needed.
