All source/destination connections are maintained even when the RCS-2700 is
not powered. The switched connections are isolated from any other internal
wiring and are rated at two amperes. Consequently, the RCS-2700 can be used
for switching applications not limited to intercom. In addition to party-line
intercom, other applications include 70-volt speaker switching and industrial
applications limited only by the designer’s imagination.
WIRING SOURCE CHANNELS IN AN 8-SOURCE SYSTEM
Wiring Source Channels
In 8-source systems, the source channels are wired as shown in Figure 2-17. The
pinout to the XLR cables connecting to main stations or power supply channels
is simply 1-2-3 from left to right. Pin 3 is the switched connection.
Wiring Source-8 Connection Points
The source-8 connection points, which have been wired out to pins on the rear
panel labeled “source expansions” (as explained in the previous section, “Basic
Switching Theory”) must now be wired together as shown in Figure 2-17. The
leftmost wire coming from the source expansion connector in the diagram
connects the joined sources to source 8 and its termination. The same source
wiring applies to expansion units 2 and 4, if they are used.
