Shure PA821B Antenna Combiner for PSM Wireless Systems
The PA821B active broadband antenna combiner streamlines the simultaneous operation of many PSM systems at a venue. The PA821B combines the RF outputs from up to eight PSM transmitters into one RF output to feed a single transmit antenna. This provides significantly improved reception quality due to reduced intermodulation distortion and dropouts due to multipath interference.
The PA821B is compatible with the wireless personal monitors Shure PSM 300, PSM 900 and PSM 1000.
