Shure PA421A Antenna Combiner IEM

Shure PA421A Antenna Combiner IEM In ear combiner

Four-to-one PSM antenna combiner for all P4T, P6T, P7T, P9T and P10T transmitter (470-952 MHz).

The PA421A active broadband antenna combiner provides a significant improvement in reception quality for up to four PSM wireless transmitters by combining them to a single antenna. This will reduce intermodulation distortion and also avoid dropouts due to multipath interference.

• Combines up to four 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.
• 4 Input LED Signals (green when active; off when inactive).
• Active-channel amplifier power for additional reductions in ambient unit heat.
• Passive (non-powered) antenna combining.

The PA421A is compatible with the wireless personal monitors Shure PSM 400 PSM 600, PSM 700, PSM 900 and PSM 1000.
