COMPONENT/PART SYMBOL DESCRIPTION

Important:

The designated circuits where implemented 2 (two) different ground connections:

1. Power Ground

The Power Ground by mean the common ending for all subcircuits with relative highcurrent voltage intensity and contains stream/signal that may be carrying the AC hum.

2. System Ground

The System Ground by mean the common ending for all highsensitive subcircuits and ending for those processes the small audio signal.

RELAY / VOLTAGE CONTROLLED SWITCH

SAFETY INSTRUCTIONS SYMBOL DESCRIPTION

Alerts you to the presence of insulated dangerous voltage, or indicates a live area on the circuit, that may be sufficient to constitute a risk of shock.

Alerts you to important maintenance instructions in the accompanyingliterarture.
