Shure AD221 Axient Digital PSM 2-Way Passive Combiner/Splitter
AD221 Overview
The Shure AD221 is a passive 2-way combiner/splitter built specifically for Axient Digital PSM in-ear monitor systems, enabling streamlined antenna distribution across multi-system deployments. It operates bidirectionally, combining two incoming RF signals into a single output or splitting one input into two discrete outputs. When used with ADTQ or ADTD Axient Digital PSM transmitters, the AD221 supports signal gain compensation to counteract the inherent level loss introduced by passive combining. Audio engineers, system integrators, and touring production teams will find the AD221 essential for consolidating antenna infrastructure in dense RF environments.
The AD221 simplifies cabling and antenna management at venues where multiple Axient Digital PSM systems operate simultaneously, reducing rack space requirements and antenna footprint without sacrificing RF integrity.
