Preplanning is essential in order to maximize system efficiency. We recommend the following as a means of helping you reach that goal. Make a diagram of your proposed system by laying out the relative location of each component in the system. Then lay out the proposed cable runs between them. Number each cable and record its length on the diagram for future use. Cable runs are critical in that they must be kept away from the sources of power radiation (amplifiers, power cords, heaters, appliances, etc. ). For safety reasons, they should also be kept out of traffic areas. The process of optimizing the system will include the type of cable, the length of the run, and the obstructions it must deal with along its run. Your dealer can advise you on the products available and their relative merits. If building custom length audio cable is not your strength, you dealer should be able to help you with that as well.
