User manual HECO VICTA 701

[. . . ] 5 mm² for lengths up to 3 m and at least 4 mm² for lengths above 3 m. For good sound it is imperative that the cables must be connected in such a way that the speakers are "in phase". This means that the black negative terminals on the speakers (-) must be connected to the negative (-) terminals on the amplifier, the red positive (+) speaker terminals to the positive (+) amplifier terminals. To make this easier one wire of most speaker cables is marked with a coloured strip or a ridge in the insulation. [. . . ] The rear loudspeakers are placed at ear height or a little above on the left and right besides or better behind the listening position. The special connection terminals of the Victa loudspeakers support both conventional connection and operation in bi-wiring and bi-amping modes. There are four screw terminals on each speaker. The top pair are for the tweeter (high frequencies), the lower pair for the woofer (low frequencies). The factoryinstalled metal strips connecting the positive and negative terminals are for conventional 2-wire connection and must be removed for bi-wiring and bi-amping operation. The pictures below show the correct set-up for conventional operation (Fig. The loudspeaker is placed immediately on or under the television set. Bi-wiring means using separate cables to carry the high and low audio frequencies. Bi-amping takes this idea one step further and uses separate power amplifiers as well as separate cables for high and low frequencies. Always turn the volume down immediately as soon as you hear distortion!If you like listening to loud music make sure that your amplifier can deliver at least as much power as the speakers' power-handling rating. Weak amplifiers with low output ratings can actually be more dangerous for your speakers at medium volumes because weak amplifiers may overload much faster than powerful ones and this causes measurable and audible distortion, which is extremely dangerous to your loudspeakers. If the output of your amplifier is significantly higher than the rated power handling capacity of your speakers extremely high volumes can physically destroy your speakers. This doesn't actually happen often but you should be aware that it is possible. All HECO loudspeakers are designed and built for optimum sound reproduction with the tone controls in the central position ­ i. Turning up the bass and treble controls too far delivers more power to the woofers and/or tweeters, and at high volumes this can actually destroy the speaker units!Amplifiers, tuners and CD players can all produce inaudible high-frequency signals ­ and this doesn't only apply to cheap products. If your tweeters fail at low or medium volumes you should have a qualified technician check your system components for dangerous inaudible signals.
