7.1. How to Divide the Speaker Lines of the Junction Panel
Junction panel's power amplifier terminals can be divided for a group of consecutive five lines.
For multi-origination broadcast, remove jumper wires on the power amplifier terminals so that the outputs of
the power amplifier panel are divided for each broadcasting zone.
• The 10-zone Expansion Junction Panel JP-039-10 is not equipped with terminals C3, C4, H3, and H4.
• Remove jumper wires from both C and H terminals depending on the combinations.
