AXIENT DIGITAL PSM 2-WAY COMBINER SPLITTER 470-960 MHz

The Shure AD221 is a professional 2‑way passive combiner/splitter designed for use with Axient Digital PSM in‑ear monitoring systems. It allows you to either split one incoming RF signal into two outgoing signals or combine two incoming signals into one. This functionality helps streamline the antenna setup in complex wireless systems, especially in live events, theater, broadcast, and large‑scale RF environments. When paired with ADTQ or ADTD Axient Digital PSM transmitters, the AD221 supports automatic transmitter compensation and helps defend against passive signal loss. The device is compact, passive (no external power), and built for reliable signal distribution and easier system integration.
