[. . . ] For clean installation in solid masonry walls, we recommend the use of a special accessory installation frame which neatly covers the installation opening. This installation frame may be ordered through Canton Customer Service. Since installation of InWall speakers is permanent, the installation point should be carefully considered. Keep in mind that furniture may be moved at times and that, once selected, the installation point of the InWall systems cannot be changed all that easily. [. . . ] The most reliable way to assure this is to see that the output power of the amplifier and the power handling rating of the speakers conform with each other. However, even amplifiers with greater power are no danger if you are sure not to turn up the volume higher than tolerable. As a rule, danger to loudspeakers is more likely to be caused by lowpowered amplifiers since, when attempting to achieve greater sound pressure by turning up the volume and tone controls, they are overdriven and go into so-called , , clipping", creating overtones which can destroy speaker tweeters in particular. Use the enclosed installation template to ascertain the exact size of the wall cutout. Now hollow out an appropriate installation opening in the wall/ ceiling. When laying loudspeaker cable from amplifier to installation point, be sure that the cable ends protrude about 30 cm beyond the wall cutout. Before fastening the speaker cable to the screw clamps of the InWall systems, you must first split the two-conductor cable and strip off about 1. Now connect the marked cable (+) with the red screw clamp on the crossover network, the second cable (-) with the black screw clamp. Make sure that the red mounting tabs (6 per InWall system) do not stick out (photo above), but are in a position facing the inside (photo underneath) so that the InWall system will fit in the installation opening. Now the speaker system can be inserted into the wall cutout and can be secured using the silver screws. Important: To prevent damage to the mounting tabs, do not twist the screws too tightly. In order to make the installation under problematic conditions easier it is possible to separate the baffle of the InWall system from the frame. Make sure that the red mounting tabs (6 per InWall system) are in a position facing the inside (photo underneath) so that the InWall system will fit in the installation opening. After that the frame can be inserted into the wall cutout and can be secured using the silver screws. Important: To prevent damage to the mounting tabs, do not twist the screws too tightly. Before fastening the speaker cable to the screw clamps of the InWall systems, you must first split the two-conductor cable and strip off about 1. Now connect the marked cable (+) with the red screw clamp on the crossover network, the second cable (-) with the black screw clamp. Once this contact is established, the speaker system can be screwed into the installation frame using the six black screws. The crossover networks of the InWall systems provide for adjustment of treble level by +/- 2 dB to suit personal listening preference and acoustic conditions. For sound reproduction with flat frequency response, the control is set in a neutral position (O). By turning the control counter-clockwise, the level is reduced by 2 dB. Frames of the InWall systems are made of white ABS plastic and, like the white-painted perforated grille, can be overpainted with standard paints to suit individual taste. [. . . ] To expand a stereo system into a complete Home Theater system, you will require a special magnetically-shielded Center Speaker. Augmenting speakers for left and right channels, it reproduces the center channel. You will find a large selection of Center Speakers for expanding stereo setups into Home Theater systems in the current Canton loudspeaker range. Please note: If InWall systems are to be used near a TV set, the speakers should be positioned at a distance of about 1. [. . . ]
