4-TO-1 COMBINING FOR PSM TRANSMITTERS
Using the supplied BNC-BNC cables, connect the Antenna Output
1.
of each transmitter to the Antenna Inputs of the PA421SWB (See
Figure 2).
Attach an antenna to the MAIN Out of PA421SWB. For wideband
2.
applications, use PA805SWB directional antenna (Figure 2).
Connect the PA421SWB to a power outlet using one of the supplied
3.
power cables. The PA421SWB contains a universal power supply to
operate anywhere in the world.
If you have a Shure PSM system that has the same power input
4.
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.
NOTE: The PA421SWB supplied power is 15 V and up to 660 mA.

NOTE: When the PA421SWB is powered on, the input signal
indicators (1-4) on the front panel will illuminate if an active
transmitter is connected to the corresponding input (1-4) on the
back panel (Figure 2).
