Streamline your Axient PSM transmit antenna setup with the AD221 Axient Digital PSM 2-Way Combiner/Splitter from Shure. The unit splits an incoming signal into two outgoing signals or combines two incoming signals into one signal, allowing you to use fewer antennas and helping to eliminate intermodulation noise when multiple antennas are deployed in the same space. The AD221 enables Automatic Transmitter Compensation when used with the ADTQ or ADTD Axient Digital PSM transmitters, which helps defend against passive signal loss.
