Page/Party ® Line Balance
For proper system operation, the page line and party lines 1–5 must be terminated with a resistance of
approximately 33 ohms. The Model LE200-RM provides potentiometers to set the line balance resistance
on the page line and five party lines. The line balance resistors are located on the Audio Termination
Connection Module (part of Model 12118-011 Kit) next to the page and party line terminal blocks. The
line balance resistors are adjustable or can be disabled using shorting clips P1–P7.
If connecting an LE200-RM to the same system cable segment as an ADVANCE Page/Party Interface
(PPI) card, disable the line balance for party lines 1, 2 and the page line. The PPI card provides the line
balance resistors for these audio lines. Refer to Figure 4 for the location of the jumpers and potentiometers
on the Audio Termination Connection Module and the Table 15 for setting details.
