FIGURE 12.
Using the termination plugs supplied with the ES4000A for mixed wet- and dry-line operation. In this
example, channels 5 and 6 are powered from a PS2000L Power Supply (wet lines), while channels 3 and 4 are operated
without power (dry lines). Any remote station connected to channel 3 or 4 must supply its own power. For example, a
US2000A that is powered by a PS-L Power Supply could be connected to channels 3 and 4. The advantage of dry-line
operation is that intercom stations may be operated over a much greater distance.
