1.2.2 System Block Diagrams
The following figures contain System block diagrams showing the basic signal flow
and configuration for each Atlas Series™ Transmitter Model. Figure 1-2 shows the
Medium Power single cabinet system with up to 8 PA modules. Note that a driver is
not needed, as the exciter power is sufficient to drive up to 8 PA modules. Figure 1-
3 shows the High Power configuration which is simply the addition of a second
cabinet and a cabinet combiner for outputs of 4.3Kw and 5.7kW.
