Power requirements
Power requirements for electrical equipment differ from
area to area. Please ensure that your machine meets the
power requirements in your area.
If in doubt, consult a qualified electrician.
220 V, 50 Hz for Europe except UK
240 V, 50 Hz for UK and Australia
110/120/220/240 V, 50/60 Hz convertible for other
countries.
Voltage conversion
(Not on all models)
Models for Canada, USA, Europe, UK and Australia are
not equipped with this facility. Each machine is preset at
the factory according to its destination, but some ma-
chines can be set to 110 V, 120 V, 220 V or 240 V as re-
quired.
If your unit’s voltage can be converted:
Before connecting the power cord, turn the VOLTAGE
SELECTOR located on the rear panel with a screwdriver
until the correct voltage is indicated.

What you should know to protect yourself
~ @ Never touch the plug with wet hands.
@ Always pull out by the plug and never the cord.
@ Only let a qualified professional repair or reassemble the
amplifier. An inexperienced person might touch the internal
parts and receive a serious electric shock.
@ Never put anything, especially metal, into the amplifier.
Protect the amplifier too
@ Use only a household AC power source. Never use a DC
power source.
@ |fwateris spilled on the amplifier, disconnect it and call your
dealer.
@ Make sure that the amplifier is well ventilated and away
from direct sunlight.
@ To avoid damage to the internal circuits and the external
surface, keep away from heat (stoves, etc.).
@ Avoid using spray type insecticide near the amplifier. It can
damage the finish and might ignite suddenly.
@ To avoid damaging the finish, never use paint thinner or
other similar chemicals to clean the amplifier.
@ Place the amplifier on a flat and solid surface.
@ |fyou don’t plan to use the amplifier for along period of time,
disconnect the power cord.

Connections
Before beginning
@ Turn off all the components before connecting.
@ Connect the power cord last.
@ Make sure that you connect the white PIN-plug to the left
(white) jack and the red PIN-plug to the right (red) jack.
@ Connect everything securely. Loose connections can lead
to malfunction.
@ To prevent damage to the cords, connect and disconnect
by holding the plug, not the cord.
@ To avoid distortion, make sure that the power cords and the
connection cords do not get tangled with each other.

The speaker system
Speaker placement
The playback characteristics of the speaker system(s) are
greatly influenced by the placement and the room in which the
speakers are used. For example, if the speaker system is
placed near a hard wail, the bass will sound better but the
treble might seem too strong. Play back some music without
using the tone controls and move the speaker system around
to find the best location. However, please keep the following in
mind.
Place the speaker system:
®@ On a flat and solid surface which does not transmit too
many vibrations.
@ Ina place that is well ventilated, and not very humid.
@ Away from direct sunlight and heat sources (stoves, etc.).
@ Away from your turntable and TV.
To prevent damage to the speaker
system
@ Do not raise the volume too high.
@ Turn off the amplifier when changing or connecting the
player system’s cartridge.
@ Lower the volume when changing radio stations and when
cueing or reviewing tapes.
@ Do not touch the speakers’ diaphragms.
How to clean the speaker system(s)
® Clean the speaker system(s) with a soft, dry cloth.
@ If itis very dirty, use a mild detergent.
® To protect the diaphragms (the vibrating parts), do not
spray liquid cleaner directly on the speaker system. Always
spray it on a cloth first.
@ Never use alcohol, paint thinner or a spray-type insecticide
near the speaker system, as this will damage the finish.
After
all
connections
have
been
made
Connect the power cords to an optional audio timer or directly
to your household AC outlets.
Important
The illustrated power plugs and cords are intended for
general reference. The power plug and cord used in your
country may differ from the illustrations. (Example; U.K.,
Australia, U.S.A., Europe etc.)

Protection circuit
This amplifier includes a built-in protection circuit that is acti-
vated to protect the speakers from noise damage when the
amplifiers power is turned on.
The protection circuit also functions during playback to pro-
tect the speakers from overloads, and to protect the circuit
from damage. When speakers with less than the rated imped-
ance are used, the protection circuit will short-circuit the ® and
© speaker cords.
When the protection circuit is engaged, the output signal will
be cut automatically.

2? Adjust the volume with the VOLUME control.
Attention
@ Do notlisten for long periods of time at high volume levels,
as this may damage your hearing. .
@ When connecting a pair of headphones during playback,
turn down the volume first.
Using a graphic equalizer connected
5 to the amplifier
Set the SOURCE DIRECT button to OFF before beginning
playback of the source.
Note:
Output signal levels of graphic equalizers differ from unit to
unit. Because of this, the playback volume levels may increase
or decrease suddenly if the position of the SOURCE DIRECT
button is changed during playback.
If you wish to change the setting of the SOURCE DIRECT but-
ton during playback, first turn down the volume with the VOL-
UME control.
_ Attention
To prevent distortion when using the graphic equalizer dur-
ing playback, do not set the frequency level controls to their
maximum positions.
Should the sound be cut during playback:
@ Turn off the amplifier.
@ Check for and correct the cause.
© Turn the amplifier back on.

Recording
Before beginning
@ Turn on all the components.
@ If using a DAT for recording, set it for analog recording.
