The exclamation point printed next to the output terminals of the amplifiers is, in addition to the CLASS 2
WIRING text, intended to alert users to the risk of hazardous voltages. Output connectors that could pose a risk
are marked with the exclamation point. Do not touch the output terminals while the amplifier is switched on.
Make all connections with the amplifier switched off.
