User manual HECO INC 602

[. . . ] Heco INC/INW speakers have an ingenious clamping mechanism that enables you to easily fit them into a hole cut into a baffle. The easiest way is to fit them in a plaster board or similar ceiling. When using an opening in a masonry wall, a plaster or timber board is also needed. [. . . ] The loudspeaker terminals are equipped with a clamping mechanism (fig. Press the terminal head down and guide the stripped cable end into the hole on the side. 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. 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!It is advisable to conduct the optimum setting according to your own personal listening preferences. We recommend the following switch positions as a basic setting for various listening areas: Listening area Example Switch position , , treble" -3dB 0dB +3dB Switch position , , midrange" -3dB 0dB 0dB Low sound-absorbing setup Normal sound-absorbing setup High sound-absorbing setup Wet rooms, hard reflective surfaces, tiles, large glass areas, rooms with minimal furniture Carpets, glass surfaces with curtains, leather objects, rooms with a normal amount of furniture Carpets, upholstered objects, heavy curtains, rooms with lots of furniture The tweeter's "swivel" technology allows it to be pivoted by up to 35 degrees, thereby enabling ideal sound dispersion and perfect alignment to the listening area: 5 shows the loudspeakers connected to a stereo amplifier in conjunction with a subwoofer (option). 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!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. 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. Amplifiers, tuners and CD/DVD 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.
