Notes:
• Use terminal block 1.1 for 75W circuit wiring
• For one 75W circuit and one 25W circuit place two jumpers (WC-1008) on the
connectors marked 1 and 2, 2 and 3, and leave jumper 3 OFF the 3 to 4 connector.
• All circuits are power limited and supervised.
• See speaker wiring chart for wire gauge selection.
