3 Put the cover of the battery compartment back on to the back of the remote control.

Replacing the batteries:

If the surround sound system cannot be operated properly or cannot be operated any longer with the remote control, then the batteries have to be replaced. Always replace both batteries, in order to be able to use the remote control at full capacity again.

Note:

Do not dispose of used battery in household waste! Throw away used batteries at a waste collection or disposal point or there, where you bought the batteries.

If you should want to dispose of the remote control of the surround sound system itself, then you have to remove the batteries beforehand!

To guarantee that the remote control operates perfectly:

Always point the remote control at the center speaker
- Ensure that there are no obstacles between the remote control and the center speaker which prevent reception
- Do not move more than 5 meters away from the center speaker when using the remote control. Disturbances could otherwise arise when operating the surround sound system with the remote control.

6.3. Positioning the speakers and the subwoofer

The speakers should be positioned as follows to provide an optimal sound:

• Front right and left speaker on the right and left of the television or your listening position
  Center speaker in the middle between the front left and right speaker
• Rear right and left speaker on the right and left behind your listening position
• Subwoofer: The human ear cannot locate the low tones of the subwoofer. Therefore the installation location of the subwoofer is optional.

6.4. Connect speakers and subwoofer

Use the three shorter speaker cables to connect

the center speaker and
- the front right and left speaker to the subwoofer.

Use both the long speaker cables to

• connect the rear right and left speakers to the subwoofer.

Note:

The four small speakers are identical. You can use any of these speakers as front or rear speaker.

Use the data cable to connect the center speaker to the subwoofer.

1 To connect the front and rear speakers insert

• the end of the grey leads of the speaker cable into the red terminal and
• the end of the black lead of the speaker cable into the black terminal on the back of the loudspeaker.

2 Then insert

• the end of the grey lead of the speaker cable into the red terminal and
• the end of the black lead of the speaker cable into the black terminal on the back of the subwoofer.

Insert the individual speaker cables into the following terminals:

• the cable of the front right speaker into the terminal marked FR
• the cable of the front left speaker into the terminal marked FL
  the cable of the center speaker in the terminal marked C
• the cable of the rear right speaker into the terminal marked SR
• the cable of the rear left speaker into the terminal marked SL

3 To connect the center speaker to the subwoofer: Insert the data cable into the DISPLAY LINK jack on the back of the subwoofer. Then tighten both screws on the plug. Insert the other end of the data cable into the jack on the back of the center speaker. Lastly also tighten both screws on the plug.
4 Now insert the power cord of the subwoofer into a power socket.
5 Switch the power switch on the back of the subwoofer to ON. STANDBY/MUTE will appear in the display of the center speaker.

6.5. Connecting the surround sound system to audio/video equipment

You have the following options in using the surround sound system:

A Playback of 5.1 channel surround sound on DVDs being equipped accordingly. For this purpose the surround sound system has to be connected to a DVD player, which has
a DTS and/or AC3 decoder and
- six cinch audio outputs for front and rear speakers, center speakers and subwoofer.
B Playback of simulated 5.1 channel surround sound if the audio/video devices connected only have stereo sound. This is made possible by using the so-called "Q SOUND".
C Playback of stereo sound from a connected audio/video device.

The following audio/video equipment can be connected to the surround sound system:

Television
Video recorder
DVD player
Hifi system
Computer

and other comparable devices. Audio/Video equipment can be connected to the surround sound system in the following ways:

6.5.1. Connection via 5.1 channel/audio outputs

If you would like to play back 5.1 channel surround sound (from a DVD which has been equipped accordingly), the DVD player must have 6 cinch jacks as audio outputs. These are mostly marked with "5.1 Audio Out", "5.1 Ch Audio Output" (or similar). All six cinch jacks are also marked with the audio channel, whose signal they output. The markings are mostly:

• "C", "Center" or similar for the center speaker
• "FL"/"FR", "Front L"/"Front R" or similar for the front speakers:
• "SL"/"SR", "Rear L"/"Rear R" or similar for the rear speakers
• "SW", "Subwoofer" or similar for the subwoofer

Note:

Please note that not all DVDs offer 5.1 channel surround sound. You can find information on this mostly on the DVD cover, on the DVD itself or the enclosed booklets.

1 Insert one cinch cable each (not included in the scope of supply, can be bought in specialized audio/video shops) in each of the six cinch jacks of the DVD player to be connected.
2 Insert the other end of the cinch cables into the corresponding cinch jacks on the back of the subwoofer:

the cable for the center speaker in the jack marked C
the cable for the front left speaker in the jack marked FL
the cable for the front right speaker in the jack marked FR
the cable for the rear left speaker in the jack marked SL
the cable for the rear right speaker in the jack marked SR
the cable for the subwoofer in the jack marked SW

It may perhaps be necessary to adjust the settings in the internal menu of the DVD player, so that the sound playback works properly with the surround sound system. In case of doubt consult the operating instructions of the audio/video equipment.

6.5.2. Connection via two cinch jacks as audio output

If the audio/video device to be connected to the surround sound system only has two cinch jacks:

1 Insert one cinch cable into each of the cinch jacks.
2 Insert the other end of the cinch cable into one of the pairs of jacks

AUX L/R
TV L/R
CDL/R

on the back of the subwoofoers. It does not matter which of the three pairs of jacks you use. If you would like to connect several audio/video devices simultaneously, it is less confusing if you connect them to the jacks with the relevant marking, i.e.:

• a television to the jacks marked TV
• a CD player/a hifi system to the jacks marked CD
• other devices to the jacks marked AUX.

Note:

It may perhaps be necessary to adjust the settings on the connected audio/video device so that the sound playback works properly with the surround sound system. In case of doubt consult the operating instructions of the audio/video equipment.

6.5.3. Connection via Scart /Euro AV jacks

If the audio/video equipment to be connected does not have any of the named audio outputs, but instead has a scart jack: Connect the device by using a scart cinch adapter cable. This can be done e.g. if you would like to play back the sound of a stereo television with the surround sound system. Scart cinch adapter cables can be bought in specialized audio/video shops.

To connect the audio/video equipment in this manner:

1 Insert the scart plug of the scart cinch adapter cable into the jack marked Scart/Euro AV of the audio/video device.
2 Insert the cinch plug of the scart cinch adapter cable into one of the pairs of jacks

It may perhaps be necessary to adjust the settings on the connected audio/video device so that the sound playback works properly with the surround sound system. In case of doubt consult the operating instructions of the audio/video equipment.

6.5.4. Connection via the headphone output

If the audio/video equipment to be connected does not have any of the named audio outputs, but instead has a headphone output: Connect the device by using a plug-type/cinch adapter cable. This can be done, if other outputs of the audio/video device are already occupied. Plug-type/cinch adapter cables can be bought in specialized audio/video shops.

To connect the audio/visual equipment in this manner:

1 Insert the plug of the plug-type/cinch adapter cable into the headphones jacks of the audio/video device.
If the plug of the adapter cable does not fit into the headphones jacks of the audio/video device: Use a 3.5 to 6.5 ~mm plug-type adapter (can be bought in specialized audio/video shops) additionally. Put it on the plugs on the adapter cable.
2 Insert the cinch plugs of the plug-type/cinch adapter cable into one of the pair of jacks

AUX L/R
TVL/B
CDL/R

on the back of the subwoofer.

Note:

It may perhaps be necessary to adjust the settings on the connected audio/video device so that the sound playback works properly with the surround sound system. In case of doubt consult the operating instructions of the audio/video equipment.

The surround sound system is now ready for operation.
