Shure PA421A 4-Channel IEM Antenna Combiner and Power Distribution 470-952 MegaHertz

The Shure PA421A 4-Port Antenna Combiner will combine RF (Radio Frequency) signals and distribute power to up to 4 Shure PSM series transmitters. The PA421A will effectively improve overall RF performance and eliminate the clutter associated with excessive antennas and power cables.

Features:

• Combines up to four PSM transmitters to a single antenna set
  • Improved RF networking
  • Reduce rack clutter
• Quieter fan for significant reductions in ambient unit noise
• Temperature-sensitive fan power for significant reductions in ambient unit heat
• 4 Input LED Signals (green when active; off when inactive)
• 4 DC Power LED Signals (green when active; off when inactive; red when active but interrupted/shorted)
• Active-channel amplifier power for additional reductions in ambient unit heat
  • 1 Channel engaged = 1 power amplifier active
  • Updated from PA421SWB, in which all power amplifiers were active in a block, regardless of how many of the 4 channels were active
• Passive (non-powered) antenna combining (Contact Shure Service Department for more detail and availability)
