Connections

When removing green connectors for feeding cables through holes,

ensure all are refitted at the correct polarity before connection to the

amplifier.

It is recommended to take photos as a record before taking any cables

apart. This is to ensure proper reconnection; incorrect wiring may impact

performance.
