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.
PRE OUT/MAIN IN terminals
Removing the jumper pins from the PRE OUT/MAIN IN
terminals enables this unit to operate separately as a control
amplifier and a power amplifier. These terminals are used
for connecting a signal-processing system such as a graphic
equalizer or a surround-sound processor to this unit.
If such an external unit is connected to these terminals, the
VOLUME control of this unit can be used for adjusting the
overall sound level.
To connect an external unit, first remove the jumper pins
from the PRE OUT/MAIN IN terminals, and then connect
the input terminals of that unit to the PRE OUT terminals
or its output terminals to the MAIN IN terminals. For
details, refer to the owner's manual included with the unit to
be connected.
Notes
• When you do not use the PRE OUT/MAIN IN terminals, never
remove the jumper pins from these terminals. If removed, no
sound will be outputted from this unit.
• When you use this unit with an external unit connected to the
PRE OUT and MAIN IN terminals, make sure that the CD
DIRECT AMP switch and the PURE DIRECT switch on the
front panel are turned off.
• When you use this unit as a power amplifier, connect the output
terminals of an external control amplifier etc. to this unit's MAIN
IN terminals. In this case, this unit's controls will not function
except the PHONES jack and the SPEAKERS switches. Use
the controls on the external control amplifier to make volume
adjustment etc.

unit's STANDBY/ON 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
OUTLET(S) is 100 watts.
These terminals are used for custom installation system.
When this unit is connected to the components for custom
installation system, you can operate this unit with the
system remote control.
