User manual EBENCH KH 02 DOLBY PROLOGIC SURROUND SYSTEM

[. . . ] Dolby Surround ProLogic decodes programme material coded in Dolby Surround and is built into almost every home-cinema audio system. Dolby Surround ProLogic reconstructs the original four channels -- left, centre, right and effects -- which were encoded on the stereo sound tracks of the programme material. Please read the operating instructions very carefully prior to using the device and ensure that they are retained and easy to nd for future reference. All precautionary and safety procedures should be followed exactly as well as the following safety procedures. [. . . ] Please make sure that a maximum angle of 30 degrees not exceeded when directing the remote control towards the amplier. Note: Remove the batteries from the remote control if it is not going to be used for a longer period. Before you connect the amplier, 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. 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 reecting 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 oor. 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. Note: When connecting the satellite loudspeakers, make sure that the subwoofer has not already been connected to the mains. Read the operating manual for each of the devices to be connected thoroughly and carefully!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 amplier using the included cables. Make sure that all the loudspeaker cables have been connected with the correct + and -- polarity. Plug the mains plug of the amplier and the subwoofer into a wall socket and set the mains switch to ON. Use the buttons on the front of the amplier or the remote control to select the appropriate signal input. Now adjust the main volume using the VOL +/-- buttons on the remote control or on the ampli er itself. The LED display indicates 00 when the balance is set exactly in the middle. [. . . ] 4 Problem: The sound is interrupted when listening to music or there is nothing to be heard although the mains switch is switched on. 4 Problem: There is no video signal to be seen on the television when the input selection switch is switched to DVD 5. 4 Possible cause: Video outputs for the DVD player and VCR unit have been connected up the wrong way round. Move closer to the amplier with the remote control to make sure you are within the receiver range of the infrared receiver. [. . . ]
