Shure AD221 Axient Digital PSM 2-Way Combiner-Splitter
The Shure AD221 is a passive 2-way combiner and splitter for Axient Digital PSM in-ear monitor systems, covering 470 to 960 MHz.
It combines two incoming signals into one or splits one signal into two, so several Axient Digital PSM systems are simpler to use at a venue.
It supports signal gain compensation with the ADTQ and ADTD transmitters, and it has a back plate for mounting.
