Shure | PA421B-E - Active Antenna Combiner for PSM

Shure - PA421B

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 four 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. (Directly replaces PA421A.)

Features

• Combines up to four PSM transmitters to a single antenna set for improved RF networking & reduced rack clutter.
  
• Wideband operation (470-865 MHz)
  
• 4 Input LED signals (green when active; off when inactive)
  
• Quieter, temperature-sensitive fan for significant reductions in ambient unit noise and heat
  
• Daisy-chain up to 2 combiners with the expansion port.
  
• LED indicators for signal presence and signal overload
  
• Passive (non-powered) antenna combining*
