POWER-CORD CAUTION

Handle the power cord by the plug. Do not pull out the plug by tugging 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. The power cords should be routed such that they are not likely to be stepped on. A damaged power cord can cause a fire or give you an electrical shock. Check the power cord once in a while. When you find it damaged, ask your nearest PIONEER authorized service center or your dealer for a replacement.

VENTILATION CAUTION

When installing this unit, make sure to leave space around the unit for ventilation to improve heat radiation (at least 25 cm at top, 15 cm at rear, and 10 cm at each side).

WARNING

Slots and openings in the cabinet are provided for ventilation to ensure reliable operation of the product, and to protect it from overheating. To prevent fire hazard, the openings should never be blocked or covered with items (such as newspapers, table-cloths, curtains) or by operating the equipment on thick carpet or a bed.

If the AC plug of this unit does not match the AC outlet you want to use, the plug must be removed and appropriate one fitted. Replacement and mounting of an AC plug on the power supply cord of this unit should be performed only by qualified service personnel. If connected to an AC outlet, the cut-off plug can cause severe electrical shock. Make sure it is properly disposed of after removal. The equipment should be disconnected by removing the mains plug from the wall socket when left unused for a long period of time (for example, when on vacation).

CAUTION

The POWER switch on this unit will not completely shut off all power from the AC outlet. Since the power cord serves as the main disconnect device for the unit, you will need to unplug it from the AC outlet to shut down all power. Therefore, make sure the unit has been installed so that the power cord can be easily unplugged from the AC outlet in case of an accident. To avoid fire hazard, the power cord should also be unplugged from the AC outlet when left unused for a long period of time (for example, when on vacation).

Replacement and mounting of an AC plug on the power supply cord of this unit should be performed only by qualified service personnel.

IMPORTANT: THE MOULDED PLUG

This appliance is supplied with a moulded three pin mains plug for your safety and convenience. A 10 amp fuse is fitted in this plug. Should the fuse need to be replaced, please ensure that the replacement fuse has a rating of 10 amps and that it is approved by ASTA or BSI to BS1362.

Check for the ASTA mark or the BSI mark on the body of the fuse.

If the plug contains a removable fuse cover, you must ensure that it is refitted when the fuse is replaced. If you lose the fuse cover the plug must not be used until a replacement cover is obtained. A replacement fuse cover can be obtained from your local dealer.

If the fitted moulded plug is unsuitable for your socket outlet, then the fuse shall be removed and the plug cut off and disposed of safely. There is a danger of severe electrical shock if the cut off plug is inserted into any 13 amp socket.

If a new plug is to be fitted, please observe the wiring code as shown below. If in any doubt, please consult a qualified electrician.

IMPORTANT: The wires in this mains lead are coloured in accordance with the following code: Blue : Neutral Brown : Live

As the colours of the wires in the mains lead of this appliance may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows ;

The wire which is coloured BLUE must be connected to the terminal which is marked with the

letter N or coloured BLACK.

The wire which is coloured BROWN must be connected to the terminal which is marked with the

letter L or coloured RED.

How to replace the fuse: Open the fuse compartment with a screwdriver and replace the fuse.

IN COMBINATION WITH SPEAKERS

The frequency characteristics of the S-LX70W combined with small-size speakers are shown below. As shown in these figures, the low frequency range is improved.

• These special characteristics are obtained in an echoless chamber. The effect of an additional S-LX70W in an ordinary listening room is better than the chart indicates when positioned adequately.

RESPONCE (dB)

• With playback of Dolby* Digital, establishment of a special channel for the subwoofer is recommended; and with playback of LFE (Low Frequency Effect: sound effect like the rumbling of the earth, whose purpose is to intensify the force of the video), the S-LX70W is especially effective.

Dolby* Digital

Dolby Digital is the name of the Dolby Surround multichannel digital system that was developed from Dolby Surround, as a continuation of Dolby Pro Logic Surround.

Dolby Digital is also referred to as a 5.1 channel system. This is because it has 5 channels in the 20 Hz to 20 kHz frequency range (front left and right, center, and rear left and right) and an independent channel for the subwoofer. The subwoofer channel is also referred to as LFE (Low Frequency Effect).

The LFE channel is used according to individual tastes to enhance the bass effect.

INSTALLATION

Speaker Installation

• Subwoofer Installation Criteria 1 Left speaker 2 Right speaker 3 Recommended installation range for the

subwoofer

4 Listening position

NOTES:

• To avoid interference with the picture on a nearby TV set, use magnetically shielded speaker systems. This is particularly important for the center speaker since it is usually located closest to the TV.

• Position the left and right channel speakers at equal distances from the TV set and approximately 1.8 meters from each other.

• Install the center speaker above or below the TV so that the sound of the center channel is localized at the TV screen.

• The rear (surround) speakers are most effective when installed in parallel locations directly to the side, or slightly behind, the listener, at a level about 1 meter above the listener’s ears.

CAUTION:

When installing the center speaker on top of the TV, be sure to secure it with tape or some other suitable means.

Otherwise, the speaker may fall from the TV due to external shocks such as earthquakes, and it may lead to endangering those nearby or damaging the speaker.

The subwoofer plays back the bass in monaural, making use of the fact that the human ear is not very sensitive to the direction of low-pitched sound. Because of this, the subwoofer can be installed almost anywhere. If it is installed too far away, however, the sound from the other speakers may become unnatural.

Installation Precautions

• Install the unit in a well-ventilated location where it will not be exposed to high temperatures and high humidity.

• Do not place the unit near stoves or other heating equipment or at locations exposed to direct sunlight, as these can have an adverse effect on the cabinet and internal components. Also, do not install the unit where there is too much dust or high humidity, as these can cause malfunctioning or breakdowns. (Avoid cooking tables and other locations where the unit would be exposed to heat, steam and soot.)

• Do not place heavy or large objects on top of the speaker. Doing so could provoke the speaker to fall, causing damages or bodily injury. If speakers fall from their installation locations, they may suffer irreparable cracks in their finish.

• Keep the unit away from devices such as cassette decks which are sensitive to magnetic fields.

This speaker system is magnetically shielded. However, depending on the installation location,

color distortion may occur if the speaker system is installed extremely close to the screen of a television set.

If this happens, turn off the power switch of the television set, and turn it on after 15 to 30 minutes.

If the problem persists, place the speaker system away from the television set.

• Do not place the speaker on an unstable surface, as doing so may cause the speaker to fall and cause damage or bodily injury.

• Do not place cups, glasses, or other containers with fluids on top of the units, since the units may be damaged if the liquid spills.
