Warning: Only hi-fi amplifier loudspeaker outputs may be connected to the loudspeaker terminal.
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.
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.
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 (Fig. 3).
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!
