START-UP
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!
MAINTENANCE
The lacquered surface is best cleaned with a mild household cleaner. On no account use furniture polish or
similar products on these surfaces.
HOW TO AVOID DAMAGE TO YOUR VALUABLE SPEAKERS
All MAGNAT loudspeakers are designed and built for optimum sound reproduction with the tone controls in
the central position – i.e. with "linear" amplifier output. 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. This doesn't actually happen often but you
should be aware that it is possible.
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.
THE SOUND YOU CAN'T HEAR...
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.
