The Shure Axient Digital PSM 4‑Channel Wireless System is a high‑performance in‑ear monitoring platform designed for major touring acts, broadcast productions, and large‑scale events where flawless wireless monitoring is essential. Built around the ADTQ quad digital transmitter, the system leverages Shure’s WMAS technology to dramatically increase spectral efficiency, allowing up to four stereo monitor mixes to be transmitted from a single unit while maintaining exceptional RF stability and range. It uses Spatial Diversity transmission, where two antennas broadcast identical signals to guard against multipath interference, and pairs with ADXR digital bodypack receivers featuring true digital diversity for highly reliable reception in complex RF environments. Wide tuning, multichannel wideband operation, narrowband and analog FM modes, AES3, Dante, and AES67 digital inputs, and full integration with Wireless Workbench and ShowLink provide engineers with deep control over routing, monitoring, and remote adjustment of receiver settings. With features like CueMode for monitoring up to 64 encrypted mixes and extremely low digital latency, Axient Digital PSM sets a new benchmark for clarity, flexibility, and scalability in professional in‑ear monitoring.
