Dear HECO Customer,
Congratulations on your fine new loudspeakers and thank you very much for
choosing HECO! You have made an excellent choice. The high-quality speakers
produced by HECO are renowned all over the world.
Please study the instructions and information below carefully before using your new
loudspeakers.
GENERAL INFORMATION ABOUT CONNECTING YOUR HECO ALEVA
LOUDSPEAKERS
Please always use a good quality loudspeaker connection cable from an audio
dealer. To prevent impairment of sound quality, we recommend cables with cross-
sections of at least 2.5 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.
Strip 10 – 15 mm of insulation from the ends of the cables. Twist the ends – this is
much better than tinning them with solder – insert them in the terminals and tighten
the terminal screws firmly (fig. 1). Loudspeaker cables with CE-compliant banana or
single-pin plugs (4 mm) or forked fittings can also be used.
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!
