The 100 V input (IN A) is directly connected to the Ji+, Ji- (0, common)
terminals and the transformer (100V, COM), of which outputs (having
intermediate voltages) are connected to the J1 1/2, J1 1/4, J2 1/8, J2 1/16
terminals.
The output level (OUT: Jo+ e Jo- terminals) is selected by means of the 6
position selector (5 + off).
If necessary, the second audio input for paging can be routed to the output
(the selector is bypassed) through a 24 V dc command.
Both jumpers (JPA and JPB) are to be set to the position 2-3.
Example no.3: connection with the second audio line and the override relay (6 wire line)
• an audio input (100 V)
