The Shure PA821B is an antenna combiner and is a useful accessory when using PSM in-ear monitoring systems. If multiple in-ear transmitters are used in a case, the Shure PA821B ensures that 8 transmitters can be operated via one antenna. This results in an improved RF signal and higher compatibility. The Shure antenna combiner operates in the RF frequency range of 470-865 MHz.
