LINE VOLTAGE SELECTOR SWITCH
Only multi-voltage models are provided with this switch. US.,
Canadian, European, U.K., and Australian models are not
provided with this switch.
Main voitages in Saudi Arabia are 127 V and 220 V only. Never
use this model with 110 V setting in Saudi Arabia.
The line voltage selector switch is on the rear panel. Before your
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 wail socket. 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.
4, Use a medium-size screwdriver.
2. Insert the screwdriver into the groove on the voltage selector,
and adjust so that the tip of the arrow points to the voltage value
of your area.

CONNECTIONS
See page 6 for Connections.
Make ail the connections before plugging in AC cords.
CONNECTING THE SPEAKER CORDS
1. Strip off the vinyl covering and twist the tip of the
wire core.
Twist the wire core.
2. Loosen the knob and insert the wire core into the
terminal hole.
3. Tighten the knob to fix the wire core in place.
NOTE:
Do not allow the wire core to protrude and touch other terminals or
wires. /f the cores of different wires touch, damage may result to your
amplifier and/or speaker systems.
Speaker Impedance
When speaker systems are connected to only SPEAKERS A or
SPEAKERS 8B terminals, such speakers should have rated
impedance in the range of 4 Q to 16 Q.
When speakers are connected to both the A and B terminals, they
should have a rated impedance in the range of 8 Q to 16 Q.
CONNECTING THE INPUT/OUTPUT CORDS
Connect the white piug to the L (left) channel, and the red plug to the
R (right) channel. Be sure to insert the plugs securely.
Left channel OL
White plug
Red plug
The INPUT/OUTPUT terminals of this unit are dull tinplated, for high
audio quality.
Turn off the power before connecting or disconnecting plugs.
AC OUTLETS (SWITCHED)
Power supplied through these outlets is turned on and off by the
amplifier’s POWER switch. Total electrical power consumption of
connected equipment should not exceed 200 W.
AC OUTLET (UNSWITCHED)
Power flows continuously to this outlet, regardless of whether
the amplifier is switched on or off. Electrical power consumption
of the connected equipment should not exceed 100 W.
The equipment should be disconnected by removing the power
plug from the wall socket when notin regular use, e.g., when on
vacation.
NOTE:
Do not connect appliances with high power consumption such as
heaters, irons, or television sets to the AC OUTLETS in order to
avoid overheating or fire risk.

OPERATIONS
COPYING TAPES
When two decks are used, you can record the sounds from one deck
onto the other.
Application examples:
®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 of desired material onto another
tape.
When using two cassette decks
1. Load tapes for playback (pre-recorded tape) and
recording (blank tape) into the respective
cassette decks.
2. Select the copying direction with input selector
buttons and TAPE 2 MONITOR button.
@ When copying from the cassette deck of TAPE 1/DAT terminals
to the cassette deck of the TAPE 2/MONITOR (ADPT) terminals:
Set the Input selector button to TAPE 1/DAT and TAPE 2
MONITOR button to OFF.
® When copying from the cassette deck of the TAPE 2/MONITOR
(ADPT) terminals to the cassette deck of TAPE 1/DAT terminals:
Set the TAPE 2 MONITOR button to ON and the Input selector to
a position other then TAPE 1/DAT.
Operate the cassette decks to begin copying.
Set the cassette deck with the pre-recorded tape to the playback
mode. 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.
Sounds compensated via the adaptor component can be recorded
(TAPE 1 REC terminals).
1. Set the TAPE 2 MONITOR button 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 2/
MONITOR (ADPT) terminals.
Also, if two decks are used, you can copy tapes from one deck onto
the other (see the section “COPYING TAPES”)
1. Set the TAPE 2 MONITOR button to ON.
2. Operate the cassette deck to perform playback
{or recording).
NOTE:
© The source selected with the input Selector is backed up for a few
days even when the Power switch is set to off or the power cord is
unplugged.
After this period, the CD is automatically selected when the power
fs supplied.
® Be sure to perform this operation with the adaptor component
power switch in the on position. Even when not using the adaptor
component, its power switch must be left an. If the adaptor
