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.
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)
