LINE VOLTAGE SELECTOR SWITCH H038 En
The line voltage selector switch is located on the rear panel.
Check that it is set properly before plugging the power cord
into the outlet. If the voltage is not properly set or if you move
to an area where the voltage requirements differ, adjust the
selector switch as follows:
¶ Be sure to disconnect the power cord from its outlet before
making this adjustment.
¶ Use a medium-sized (flat blade) screwdriver. Insert the tip
of the screwdriver into the groove of the selector switch
and turn it so that the power voltage marking of your area
points to the arrow.
CAUTION 220 V
Power source voltage is factory adjusted 220 volts. If your area
is different, change voltage selectors settings.

FEATURES
7 Direct Energy MOS Power Amp
Pioneer introduces amp circuitry featuring HEX power
MOS FET devices for high performance. Together with
Pioneer's original Wide Range Linear Circuit technology,
this helps achieve reducing power consumption, while
maintaining the power of current models.
In terms of performance, it contributes to flat damping
factor characteristics across the audio spectrum, and im-
proved power linearity.
7 Low power consumption design
7 High-power Output........ 80 W + 80 W/4 (DIN)
55 W + 55 W/8
(DIN)
7 Wide-Range Linear Circuit
This new current feedback circuit assures improved
operating stability for flat output impedance and stable
driving of speakers across the full range of frequencies.
7 Silent microprocessor system
INSTALLATION
LOCATION
Install the unit in a well ventilated location where it
will not be exposed to high temperature or humidity.
Do not install the unit in a location which is exposed to direct
rays of the sun, or near hot appliances or radiators. Excessive
heat can adversely affect the cabinet and internal components.
Installation of the unit in a damp or dusty environment may
also result in a malfunction or an accident. (Avoid installation
near cookers etc., where the unit may be exposed to oily
smoke, steam or heat.)

CONNECTIONS
CONNECTING THE SPEAKER CORDS
2. Loosen the knob and insert the wire core into the
terminal hole.
3. Tighten the knob to fix the wire core in place.
1. Strip off the vinyl covering and twist the tip of the
wire core.
10mm
Twist the wire core.
NOTE:
Do not allow any of the cord conductors to protrude from the
terminals or touch any other conductors. Malfunctioning or
breakdowns may occur when conductors come into contact
with each other.
Speaker Impedance
When speaker systems are connected to only SPEAKERS A
or SPEAKERS B terminals, such speakers should have rated
impedance in the range of 4­16
.
When speaker are connected to both A and B terminals, they
should have a rated impedance in the range of 8 ­32
.
\
CONNECTING THE INPUT/OUTPUT
CORDS
Connect the white plug to the L (left) channel, and the red plug
to the R (right) channel. Be sure to push the plugs securely.

REMOTE CONTROL CORD
CONNECTIONS
By interconnecting the CONTROL jacks of Pioneer units with
the
Î mark, the entire system can be operated with this
remote control unit, although some of the units (AM/FM
tuner, CD player, cassette deck, etc.) may not be equipped
with remote sensors. The entire system can be operated by
a remote control unit by connecting PIONEER stereo
components to each other using the control input (CONTROL
IN) jack on each component. Use the remote control cord
supplied with the respective unit for the connection. An
example is shown in the figure. As long as you connect
"OUT" to "IN", the connecting sequence is arbitrary. When
a unit has only an "IN" connector, however, connect it last.
NOTE:
When the POWER switch is set to OFF, the components
connected to the CONTROL OUT jack can not be operated
with the remote control unit.
