Transpuls-1500 - Connecting Speakers

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.  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 colored 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!
