Precautions

On safety

• Before operating the speaker system, be sure that the operating voltage is identical with that of your local power supply.
• Unplug the speaker system from the mains if it is not to be used for an extended period of time. Disconnect the mains lead by grasping the plug. Never pull the lead itself.
• Should any liquid or solid object fall into the speaker system, unplug the unit and have it checked by qualified personnel before operating it any further.
• The mains lead must only be changed at a qualified service shop.

When turning on or off the KL-50W series TV, an amplifier or other connected equipment

Lower the volume of the speaker system to a minimum.

To avoid damaging the speaker system

• Be careful when setting the volume control of the KL-50W series TV or amplifier to avoid excessive input power.
• Do not attempt to open the enclosure or remold the speaker units.
• The grill net is not removable. Do not try to remove it.

In case colour irregularity is observed on a nearby TV screen

The speaker system is not a magnetically shielded type, however, you can install the KL-50W series TV on the speaker system.

Because the KL-50W series TV uses an LCD, it is not affected by the magnets in the speakers.

If you install any other TV set near the speaker system, colour irregularity may be observed on the TV screen.

If colour irregularity is observed....

→ Move the TV set away from the speaker system, turn off the TV set once, then turn it on after 15 or 30 minutes.

On installation

• Do not install the speaker system near heat sources such as radiators or air ducts, or in a place subject to direct sunlight, excessive dust, mechanical vibration or shock.
• Good ventilation is essential to prevent internal heat build-up in the speaker system. Place the speaker system in a location with adequate air circulation. Do not place the speaker system too close to a wall as this may obstruct the ventilation hole in the back.

On cleaning the cabinet

Clean the cabinet with a soft cloth lightly moistened with water. Do not use any type of abrasive pad, scouring powder or solvent such as alcohol or benzine.

If you have any questions or problems concerning your speaker system that are not covered in this manual, please consult your nearest Sony dealer.

Unpacking

Check that you received the following items:

• Audio connecting cord (1)
- Clip for the stabilizing belt (1)
- Screw for the clip (1)

Installation

The speaker system

To obtain better bass reproduction, we recommend that you install the speaker system on a solid floor where resonance is unlikely to occur.

Notes

• Always install the speaker system a few centimetres away from the wall.
• Do not place any object except the KL-50W series TV on the speaker system. Do not sit on it.
• If the speaker system is installed in the centre of a room, the bass may be extremely weakened. This is due to the influence of a standing wave created in the room. If this happens, move the speaker system away from the centre of the room, or eliminate the cause of the standing wave by installing something against the opposite wall such as a bookshelf.

The KL-50W series TV

Install the KL-50W series TV on the speaker system and fix the TV to the speaker system using the TV stand stabilizing belt and belt clip.

Hooking Up the System

Overview

Use either the HIGH LEVEL or LOW LEVEL terminal of the speaker system when you connect the KL-50W series TV or a separate amplifier.

• If you connect the KL-50W series TV, connect the LOW LEVEL terminal of the speaker system to the audio line out jacks of the KL-50W using the supplied audio connecting cord.
• If your amplifier has one of the following types of output jacks, connect the LOW LEVEL terminal of the speaker system to the amplifier jacks using the supplied audio connecting cord.

— LINE OUT jacks
— MONO OUT jack
— MIX OUT jack
— SUB WOOFER output jacks
— SUPER WOOFER output jacks

If the amplifier has a single output jack (e.g. MONO OUT or MIX OUT jack), connect the other end of the cord to the L INPUT jack of the LOW LEVEL terminal of the speaker system.

• If your amplifier does not have any of the above mentioned output jacks, connect the speaker terminals of the amplifier to the HIGH LEVEL terminal of the speaker system instead.
• If your amplifier has the Dolby Pro Logic Surround system, connect the center speaker output of the amplifier to the speaker system's CENTER SPEAKER terminal as well.

What is Dolby Pro Logic Surround?

Dolby Pro Logic Surround is a system that decodes the extra channels on movie videos and TV programmes, and produces sound effects and echoes that make the action seem to envelop you. The sound image is improved by using four separate channels: off-screen audio effects, on-screen dialogue, left to right panning, and music. These channels manipulate the sound and enhance the action as it happens on the screen.

The unit offers PROLOGIC mode for these systems as one of the sound fields. You can tell if a video tape or laser disc uses Dolby Pro Logic Surround encoded software by looking at the packaging. (Some video tapes and laser discs may use Dolby Pro Logic Surround even if it's not indicated on the package.)

Connecting the mains lead

Connect the mains lead of the speaker system and your amplifier to a mains outlet.

Listening to the Sound

Front side POWER POWER/ STANDBY VOLUME MIN MAX POWER

Note

The following actions may cause damage to the speakers: Setting the amplifier's tone control to a high level, setting an equalizer's output to a high level, or inputting sine waves of 20 Hz to 50 Hz recorded on a commercially available test disk or special sounds (the bass sound of electronic musical instruments, popping noise of an analog disc turntable, sounds with abnormally enhanced bass, etc.) When a special disc containing abnormally enhanced bass is played, noise may be output in addition to the original sound. In such a case, decrease the sound level.

1 Turn on the connected KL-50W series TV or amplifier and select the programme source.

2 Press the POWER switch.

The speaker system turns on and the POWER indicator lights up in red.

3 Play the programme source.

When the speaker system receives a signal, the POWER indicator turns green.

Adjust the volume of the KL-50W series TV or amplifier so sound from the front speakers is not distorted.

The standby mode

When no signal is received, the speaker system goes into standby mode and the POWER indicator turns red after a few minutes. When a new signal comes into the speaker system, the speaker system returns to active mode and the POWER indicator turns green.

To turn off the power

Press the POWER switch to release the switch.

If you hear noise when you turn off the speaker system, turn down the speaker system volume, or turn off the KL-50W series TV or amplifier before turning off the speaker system.

Adjusting the Sound

You can adjust the speaker system to complement the sound of your front speakers. Reinforcing the bass sound gives you a greater sense of atmosphere.

1 Play your favourite song.

Male vocal tunes containing bass sounds are most suitable for adjustment. Adjust the volume for the front speakers to the same level as usual.

2 Adjust volume of the speaker system.

Turn the VOLUME control so you can hear the bass sound a little more than before.

To increase the bass sound, turn the VOLUME control clockwise. To decrease the bass sound, turn the VOLUME control counterclockwise.

3 Adjust the cut off frequency.

Turn the CROSSOVER control to match the reproduction frequencies of your front speakers.

Turn the control towards 150 Hz if you have small front speakers. Turn the control towards 50 Hz if you have large front speakers. If you connect the KL-50W series TV, adjust the CROSSOVER control to the marked (KL-50W) position.

4 Select the phase polarity.

Press the PHASE button to select the phase polarity. Select the normal (+) phase polarity if you connect a KL-50W series TV.

Depressing the PHASE button reverses the polarity and may provide better bass reproduction in certain listening environments. (Bass reproduction depends on the type of front speakers, the position of the speaker system and the adjustment of the cut off frequency). It may also change the expanse and tightness of sound, and effect the feeling of the sound field. Select the setting that provides the sound you prefer when listening in your normal listening position.

Depressed position (■ -): Reverse Recovered position (■ +): Normal

Note

If the sound distorts when you turn on the bass reinforcement from your amplifier (such as, DBFB, GROOVE, or the graphic equalizer), turn off the bass reinforcement and adjust the sound.
