ABOUT THE ACCESSORY TERMINALS
2 AC OUTLETS (SWITCHED)
Use these to connect the power cords from your components
to this unit.
The power to the SWITCHED outlets is controlled by this unit’s
POWER switch or the provided remote control transmitter’s
POWER key. These outlets will supply power to any
component whenever this unit is turned on.
The maximum power (total power consumption of components)
that can be connected to the SWITCHED AC OUTLETS is 100
watts.
GND terminal (For turntable use)
Connecting the ground wire of the turntable to the GND
terminal will normally minimize hum, but in some cases better
results may be obtained with the ground wire disconnected.
