The Shure Axient Digital PSM 2‑Channel Wireless System is a next‑generation, professional in‑ear monitoring platform designed for high‑end touring, broadcast, and corporate productions that require rock‑solid RF performance and exceptional audio clarity. At its core is the ADTD dual‑channel digital transmitter, part of Shure’s new Axient Digital PSM ecosystem, which uses WMAS (Wireless Multichannel Audio System) technology to dramatically increase spectral efficiency and system scalability. This allows a single transmitter to carry multiple stereo mixes, giving monitor engineers far more flexibility than traditional IEM systems. The system also employs Spatial Diversity transmission, where two antennas transmit identical signals on the same frequency, providing powerful protection against multipath interference—one of the most common causes of IEM dropouts. True Digital Diversity in the paired ADXR bodypack receiver further improves signal stability and range. The Axient Digital PSM system supports multiple transmission modes including Wideband Multichannel, Narrowband, Analog FM (for near‑zero latency), and a standard Axient Digital mode that allows the transmitter to act like a regular AD‑series wireless audio transmitter. Audio inputs include AES3, AES67, and Dante, and the system integrates seamlessly with Shure Wireless Workbench and ShowLink for real‑time remote control of bodypack settings. Features like CueMode (monitor up to 64 encrypted mixes from a single bodypack), excellent stereo imaging, and automatic impedance detection make it a powerful tool for monitor engineers. With its breakthrough spectral efficiency, secure digital transmission, and high‑headroom audio, Axient Digital PSM sets a new benchmark for wireless in‑ear monitoring.
