LINE VOLTAGE SELECTOR SWITCH
‘Only multi-voltage models are provided with this
switch. European, U.K. and Australian models are
not provided with this switch.
Main voltages in Saudi Arabia are 127 V and 220 V
only.
Never use this modei with 110 V setting is Saudi
Arabia.
The line voltage selector switch is on the rear panel. Before
you model is shipped from the factory, this switch is set to
the power requirements of the destination. Check that it is
set properly before plugging the power cord into the AC wall

FEATURES
« Remote control integrated amplifier
The volume can be up/down using the remote control unit.
+ Wide-Range Linear Circuit
This new current feedback circuit assures improved oper-
ating stability for flat output impedance and stable driving
of speakers across the full range of frequencies.
+ High-power Output of 55W+55W/4Q(DIN), 45W+45W/
8Q(DIN)
INSTALLATION
LOCATION
Install the amplifier in a well-ventilated location
where it will not be exposed to high temperatures
or humidity.
Do not install the amplifier 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. Instalia-
tion of the amplifier in a damp or dusty environment may result in a
malfunction or accident. (Also avoid installation near cookers etc.,
where the amplifier may be exposed to oily smoke, steam or heat.)
POWER-CORD CAUTION
Handle the power cord by the plug. De not pull out the plug by tug-
ging the cord and never touch the power cord when your hands are
wet as this could cause a short circuit or electric shock. Do not place
the unit. a piece of furniture, etc., on the power cord, or pinch the
cord. Never make a knot in the cord or tie it with other cords. Tha
power cords should be routed such that they are not likely to be
stepped on. A dam. 2 power cord can cause fire or give you an
electrical shock. Check the power cord once in a while. When you
find it damaged, ask your *t PIONEER authorized service cen-
ter or your dealer for a repl ert.

2. Loosen the knob and insert the wire core into the termi-
nal hole.
3. Tighten the knob to fix the wire core in place.
NOTE:
Do not allow any of the cord conductors to protrude from the termi-
nals or touch any other conductors. Malfunctioning or breakdown
may occur when conductors come into contact with each other.
NOTE:
Do nat remove studs. Removal of the studs from the out put termi-
nals may lead to a hazardous connection with the mains supply if the
speaker cord is terminated with Banana plugs (U.K. model only).

Speaker Impedance
When speaker systems are connected to only the SPEAK-
ERS terminals, such speakers should have a rated imped-
ance in the range of 4-16 Q.
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 in

<ARB7034>
COPY THE TAPE USING TWO DECKS
When two decks are used, you can record the sounds from
one deck onto the other.
Application exampies:
© To make a tape copy with contents identical to the original
tape.
© To edit a recording of an FM broadcast in order to cut out
unwanted commercials, recording only desired material
onto another tape.
1. Load the pre-recorded tape into the cassette deck
connected to the TAPE 1/DAT terminal and the
blank tape into the cassette deck connected to the
TAPE 2/MONITOR (ADPT) terminal.
2. Set INPUT SELECTOR switch @ to TAPE 1/DAT.
* Tape copying can only be performed in one direction,
from the cassette deck connected to the TAPE 1/DAT
terminal towards the cassette deck connected to the
TAPE 2/MONITOR (ADPT) terminal.
3. Operate the cassette decks to begin copying.
Set the cassette deck with the original (playback) tape to
the playback mode, and set the cassette deck with the
blank tape to the recording mode.
TO USE THE COMPONENT CONNECTED TO
THE TAPE 2/MONITOR (ADPT) TERMINALS:
(For an adaptor component)
By connecting a graphic equalizer, source sounds (from
records, tapes, AM/FM broadcasts, etc.) can be heard with
added sound and tone compensation.
1. Set the TAPE 2 MONITOR switch © to on.
2. Play back the source.
3. Operate the adaptor component.
(For a cassette deck}
A cassette deck connected here can be operated in the same
way (recording and playback) as a deck connected to the TAPE
T/DAT terminals.
On a cassette deck with the monitor function, (3-head deck }
sound can be concurrently heard while recording on tape.
This operation of checking the sound quality and recording
level is called “monitoring”.
1. Set the TAPE 2 MONITOR switch © to on.
2. Operate the cassette deck to perform playback
(or recording).
