Product Overview

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 Shure PA821B Antenna Combiners are complementary accessories for Shure PSM Personal Stereo Monitor systems. When multiple systems are required for monitoring environments, the PA821B combiners quietly and efficiently reduce rack clutter and optimize RF management for up to eight PSM transmitters when racked in a central location.

The PA821B is compatible with the wireless personal monitors Shure PSM 300, PSM 900 and PSM 1000.
