The Shure PA821-SWB is an Eight-to-One Wideband PSM Antenna Combiner for all P4T, P6T, P7T, P9T and P10T Transmitters operating in the range 470-952 MHz.

MAIN FEATURES
Combines up to eight PSM transmitters to a single antenna set for improved RF networking & reduced rack clutter
Quieter fan for significant reductions in ambient unit noise – especially useful for installation work
Temperature-sensitive fan power for significant reductions in ambient unit heat
8 Input LED Signals (green when active; off when inactive)

The PA821A antenna combiner is the ultimate problem solver for products that are dependent on the simultaneous operation of many PSM and wireless microphone routes at a venue. As an active broadband antenna combiner with 8 inputs and output of the PA821A provides a significant improvement in reception quality and up to eight wireless transmitters can be combined in a single antenna. This will reduce intermodulation distortion and also avoid dropouts due to multi-path interference.

The PA821A is compatible with the wireless personal monitors Shure PSM 400, PSM 600, PSM 700, PSM 900 and PSM 1000. It can also be used with all other in-ear monitoring transmitter and/ or antenna combiners of the integrated passive combiner with two inputs and one output can be connected.
