Shure PA821B-E

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®900 transmitters or up to four PSM®1000 transmitters when racked in a central location.

Note: PA821B replaces PA821A.
