Frequently Asked Questions - KH 02 DOLBY PROLOGIC SURROUND SYSTEM EBENCH

How to connect the speakers to the system?

Before connecting, make sure the subwoofer is not plugged into the mains. Use the supplied cables: strip the ends about 4 mm. Connect the front speakers to the FR (right) and FL (left) terminals of the amplifier, the effect speakers to the SR and SL terminals, and the center speaker to the C terminal. Observe the + and - polarity. The subwoofer connects to the SW OUT jack of the amplifier.

How to use the remote control?

The infrared remote control works up to about 7 meters with a maximum angle of 30 degrees relative to the amplifier. Main buttons include STANDBY, MUTE, source selection (DVD/5.1, MD/CD, VCR, AUX), volume (VOL +/-, CH VOL +/-), balance (L+/R+), sound modes (SOUND MODE, CEN.MODE, DSP, BYPASS) and delay adjustment (SUR DELAY +/-). Insert the supplied AAA batteries observing polarity.

Why is there no sound?

First check that the amplifier and subwoofer are turned on (main switch ON and AUTO POWER switch ON). Ensure the source is correctly selected (DVD/5.1, etc.) and that the volume is not muted (MUTE button). Check the speaker cable and input cable connections. If sound comes from only one channel, the balance may be unbalanced; press BAL to return to center.

How to adjust Dolby ProLogic and DSP modes?

Use the SOUND MODE button to switch between Dolby ProLogic, Dolby 3 Stereo and Bypass modes. The CEN.MODE button lets you choose between NORMAL, PHANTOM and WIDE for the center effect. The DSP button offers six equalization curves: Rock, Movie, Music, Hall, Disco and Pops. To disable all effects, press BYPASS.

How to adjust the subwoofer volume?

The subwoofer volume is adjusted using the volume adjuster on the back of the device. You can also use the CH SET function on the remote control to select the subwoofer and adjust its volume with the CH VOL +/- buttons. In Dolby ProLogic mode, you can independently adjust the center speaker and front/effect speakers.

What to do if the remote control does not work?

First check the battery condition; replace them if necessary. Make sure you are within the reception range (7 m, angle < 30°). Clean the infrared sensor on the amplifier. If the problem persists, use the buttons on the front panel of the amplifier.

How to test the speaker connections?

Press the TEST button on the remote control. A humming sound will be heard sequentially on each speaker, and the active channel will be displayed on the screen. This allows you to verify that all speakers are properly connected and working.

How to adjust the surround speaker delay?

Use the SUR DELAY + and - buttons on the remote control to increase or decrease the delay in 1 ms steps. The optimal setting depends on the distance between the effect speakers and the listening position. In Dolby ProLogic mode, a slight delay improves the surround effect.

Can I connect headphones?

Yes, connect headphones with a 6.3 mm jack plug to the headphone jack on the front panel of the amplifier. The speakers are then automatically disabled.

How to maintain the system?

Clean the exterior surfaces with a soft cloth slightly dampened with mild soapy water. Never use alcohol, thinner or chemical solvents. Avoid moisture and dust. For deep cleaning, unplug the device.

If in doubt, consult the operating manual of the respective device.

Remove your new eBench Dolby ProLogic Surround System KH 02 carefully from the packaging. Keep the box for transport or storage of the system. The packaging contains the following components:

Amplifier

Loudspeakers

• 1 amplifier
  • 1 subwoofer with mains connection
  • 1 centre speaker
  • 2 front satellite loudspeakers
  • 2 effect satellite loudspeakers

Remote control

• Infrared remote control incl. 2 batteries

Inserting the batteries in the remote control

1. Open the battery compartment on the reverse of the remote control.
2. Insert the two batteries, making sure that correct polarity.
3. Close the battery compartment.
4. The range of the remote control is approximately 7 m. Please make sure that a maximum angle of 30 degrees not exceeded when directing the remote control towards the amplifier.

Note: Remove the batteries from the remote control if it is not going to be used for a longer period.

Setting up the loudspeakers

Before you connect the amplifier, the centre speaker, the front and the effect loudspeakers and the signal source(s) to the subwoofer, you should set up the loudspeakers in such a way that you get an optimum cinema sound effect in your living room. Follow the drawing below to achieve this effect.

FL SW C FR SL SR

The subwoofer should be placed on the floor at the front of the room. It can be placed near to the television set or in a corner. The rear panel of the loudspeaker should be 10 to 15 cm away from the wall in order to achieve the correct tonal balance and to allow the heat to be drawn off.

The centre speaker should be arranged straight above or below the television set and point directly in the main listening direction. It is magnetically shielded so that it will not affect the television. The two front loudspeakers should be set up on the left and right of the room, about halfway between the television set and the main listening position. Ideally they should be placed at a height corresponding to the ear height of seated listeners and be close to a wall or another reflecting surface. The effect loudspeakers can be set up directly behind your listening position or at the rear of the room. They should stand on a table or be mounted between 80 cm and 120 cm above the floor.

The subwoofer, the front and the effect loudspeakers as well as the centre speaker each have their own independent volume adjustment which can be set according to the distance to your listening position.

When all the system components have been connected up, test the setting of the volume control for the effect loudspeakers until you have found the setting that results in the surround sound effect to suit your requirements. You should usually only need to set the volume of the rear loudspeaker once and then leave it in this position, unless you change the position of the loudspeakers or re-adjust the volume on the subwoofer, the front loudspeakers or the centre speaker.

Connecting the components

Note: When connecting the satellite loudspeakers, make sure that the subwoofer has not already been connected to the mains. Switch all devices OFF at the mains switch before connecting them. Read the operating manual for each of the devices to be connected thoroughly and carefully!

Make sure that each plug is inserted correctly. To avoid problems, do not twist connection cables with mains supply cables or loudspeaker cables.

The centre speaker, the front loudspeakers and the effect loudspeakers are connected to the amplifier using the included cables.

1. Insulate the loudspeaker cables approx. 4 mm at both ends using a suitable tool. Twist the ends of the wire tight (see illustration below).
2. Connect the front right loudspeaker to the connection terminals on the amplifier marked FR.
3. Connect the front left loudspeaker to the connection terminals on the amplifier marked FL.
4. Connect the right effect loudspeaker to the connection terminals on the amplifier marked SR.
5. Connect the left effect loudspeaker to the connection terminals on the amplifier marked SL.
6. Connect the centre speaker to the connection terminal on the amplifier marked C.
7. Make sure that all the loudspeaker cables have been connected with the correct + and - polarity. Inverted connections will have a negative effect on the quality of the sound.
8. Connect the subwoofer to the SW OUT jack on the amplifier.

USING THE SYSTEM

1. Make sure that all cables are connected correctly.
2. Plug the mains plug of the amplifier and the subwoofer into a wall socket and set the mains switch to ON. Then set the AUTO POWER ON/OFF switch on the rear of the subwoofer to ON. Press the STANDBY button on the amplifier.
3. Use the buttons on the front of the amplifier or the remote control to select the appropriate signal input. The standard setting is DVD/5.1.
4. Set the television to minimum volume.
5. Switch the relevant signal source (DVD player, video recorder etc.) on.
6. Insert the medium to be played (DVD, video cassette etc.) and start playback.
7. Now adjust the main volume using the VOL +/− buttons on the remote control or on the amplifier itself. The volume level is shown accordingly in the display.
8. Adjust trebles and basses as required using the TREBLE or BASS buttons on the amplifier.
9. Adjust the left and right balance by pressing the L+/R+ buttons on the remote control if required. To reset the settings to the standard default values, press the BAL button on the remote control. The LED display indicates 00 when the balance is set exactly in the middle.
10. Press the CH SET button of the remote control to select the loudspeaker where the volume is to be set. Then adjust the volume using the CH VOL+/- buttons. In Dolby ProLogic and Centre

Mode (CEN.MODE) only the centre speaker and the front or the effect loudspeakers can be adjusted.

1. Adjust the subwoofer volume using the volume control on the rear panel of the device.
2. Depending on your individual spatial situation, the surround sound can be improved using the PHASE 0°/180° button. Test by switching between 0° and 180° which setting offers the best sound reproduction where your particular surround system is installed.
3. With the DOLBY PROLOGIC button a selection can be made between Dolby ProLogic, Dolby 3 Stereo and Bypass mode. The CEN.MODE button is used to switch between the Dolby ProLogic effects NORMAL, PHANTOM and WIDE. In Dolby 3 stereo operation, only the effects WIDE and NORMAL can be set. If Dolby ProLogic is switched off, these settings can no longer be made.
4. The DSP button is used to switch between six different equaliser curves (rock, movie, music, hall, disco and pop). Each equaliser curve has its own characteristic accentuation of the treb les, mid-tones and bass ranges.
5. To deactivate all the sound or surround effects, press the BYPASS button.
6. For optimum surround sound in the Dolby ProLogic mode, the surround loudspeakers should replay tones after a slight delay. The optimum delay depends on your individual spatial situation and can be adjusted by pressing the SUR DELAY +/- buttons. This function is used to set the delay in 1 ms steps.
7. The TEST button can be pressed to find out if all the loudspeakers are connected correctly. In this case a humming sound can be heard. The test channel is shown on the display.
8. Press MUTE if you would like to turn the sound off. The display Standby/Mute will then change to red. Press the button a second time to return to normal mode.
