Notes:
• Use terminal block 1.1,1.2, 1.3 and 1.4 for four 25W circuit wiring.
• For four circuits of 25Watts, DO NOT use any of the jumpers (WC-1008) on the
connectors on the amplifier.
• All circuits are power limited and supervised.
• See speaker wiring chart for wire gauge selection.
• Refer to Table 15 for proper end of line resistor value.
