User manual HECO THE STATEMENT

[. . . ] Any sound-absorbing or reflecting obstacles in the path will distort the sound. Any irregularities in the floor may be offset and a firm stand may be achieved with the spikes. They also decouple the loudspeakers from the base so that any undesirable resonance is avoided. [. . . ] 5 mm² for lengths up to 3 m and at least 4 mm² for lengths above 3 m. Always turn off the amplifier or receiver before connecting or disconnecting loudspeaker cables. Place the loudspeakers in their planned positions and cut the cables to the right length. The cables for both channels should always be exactly the same length. 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. 3c) Strip 10 ­ 15 mm of insulation from the ends of non-ready-made cables. Twist the ends ­ this is much better than tinning them with solder ­ insert them in the terminals and tighten the terminal screws firmly. Before switching on the system double-check all your connections and make sure that the terminal screws are tight and that there are no short circuits caused by stray wire filaments ­ this could cause serious damage to your amplifier!On no account use furniture polish or similar products on these surfaces. HOW TO AVOID DAMAGE TO YOUR VALUABLE SPEAKERS 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!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.
