1. Using the supplied BNC-BNC cables, connect the Antenna Output
of each transmitter to the Antenna Inputs of the PA421SWB (See
Figure 2).
NOTE: Electrical safety approval is based on a maximum ambient
temperature of 30°C.
2. Attach an antenna to the MAIN Out of PA421SWB. For wideband

4. If you have a Shure PSM system that has the same power input
connectors as the PA421SWB power outputs, such as the PSM400,
connect the PSM system to the PA421SWB via the supplied power
cables (see figure 2). This replaces the need for an external power
supply.
