[. . . ] The lightning flash within an equilateral triangle is intended to alert you to the presence of uninsulated , , dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute an electric shock to persons. The exclamation point within an equilateral triangle is intended to alert you to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. Read Instructions - All the safety and operating instructions should be read before the appliance is operated. Retain Instructions - The safety and operating instructions should be retained for future reference. [. . . ] Before connecting cables or changing any connections, ALWAYS turn off your amplifier. Make sure that the conductors are tightly gripped by the terminals with no loose wires that could cause a short circuit and damage the amplifier (Figure 14). Always use cables of the same type and length for left and right channels. We recommend using special speaker cables from DALI, available from your dealer. For the optimal listening experience, the right loudspeaker (as seen from the listening position) must be connected to the amplifier output terminals marked "R" or "Right. " The left loudspeaker must be connected to the amplifier output terminals marked "L" or "Left. " Even a single loudspeaker connected out-of-phase in a stereo or surround installation will make the bass weaker and the stereo image unfocused. If you are using DALI IKON in a surround system, follow the instructions included with your surround amplifier. The bottom terminal pair is internally connected to the crossover network's bass section. When bi-wiring or bi-amping, ALWAYS remove the metal jumpers between the terminals before connecting cables. For bi-wiring, connect two sets of loudspeaker cable, one to the top terminals and one to the bottom terminals. At the amplifier end, connect both sets of loudspeaker cables to the same pair of terminals on the amplifier (Figure 16). When using the IKON subwoofer with active crossover and built-in power amplifier in your stereo or surround system, there are two connection options. The DALI IKON SUB can be connected to the subwoofer output of your surround amplifier or to the line output of your stereo pre-amplifier. If you want to use DALI IKON SUB for reproduction of the special subwoofer signal from a surround amplifier with separate subwoofer output terminal, connect this to the LFE input terminal on IKON SUB. if the LFE input terminal is selected , the crossover network in IKON SUB is not active. The LFE input terminal should therefore only be used together with a special subwoofer output terminal in which the signal has already been filtered, so the subwoofer only receives the lowest frequencies. If you want to use IKON SUB to supplement the bass reproduction of a stereo system, connect the subwoofer "Line in, Left/Right" to a stereo signal on the pre-amplifier with full frequency content. The built-in crossover network in IKON SUB then ensures that the subwoofer only reproduces the lowest frequencies (see section on level adjustment and adjusting the crossover on page 15 and 16). It is possible as a no-compromise stereo solution, or for reproduction of very powerful sound pressure in a surround setup in large rooms, to use two IKON SUBs. This solution is connected in the same way, but for stereo you should only connect the left-hand channel to one input terminal on the left-hand IKON SUB and the right-hand channel to one input terminal on the right-hand IKON SUB. In all other respects, follow the instructions above - but use separate channels. [. . . ] Ensuring that you keep the volume low enough so Obviously, lots of pure, undistorted output from a large amplifier is better than a distorted signal from a small amplifier stretched beyond its capacity. The signal from a distorting (clipping) amplifier contains much more high-frequency information than an undistorted signal, and therefore puts a heavy strain on the tweeter. Consequently, speakers are most often damaged by small amplifiers having to work too hard - and very rarely by large amplifiers, which are practically running idle. It is worth noting that when the tone controls are turned above the neutral setting this significantly burdens both speakers and amplifier. [. . . ]
