Shure PA821A Antenna Combiner
- Combines up to eight PSM transmitters into a single antenna set
- Improved RF networking
- Reduced rack clutter
- 8 Input LED signals (green when active; off when inactive)
- Quieter fan for significant reductions in ambient unit noise
- Temperature-sensitive fan power for significant reductions in ambient unit heat
- Active-channel amplifier power for additional reductions in ambient unit heat
- 1 Channel engaged = 1 set of power amplifiers active
- Updated from PA821SWB, in which all power amplifiers were active in a block, regardless of how many of the 8 channels were active
