Description

The PA821B Antenna Combiner from Shure is designed to optimize RF management for Shure PSM Personal Stereo Monitor systems. It can be used when multiple systems are required for monitoring on stage, theater, and rehearsal applications.

The combiner efficiently optimizes up to eight PSM transmitters (sold separately) when racked in a central location, while also reducing rack clutter. It is built with LED indicators for signal overload and signal presence. Additionally, the unit’s fan design improves thermal efficiency and ambient noise.
