6. Distributed audio system (70 V or 100 V) or direct connection —
• if wiring a 100 V or 70 V distributed system and using the transformer, proceed to step 7.
• if bypassing the transformer and wiring directly from the amplifier, proceed to step 9.
7. Connect cables from the amplifier to the transformer on the FF 120T transformer cover plate.
