In this respect, a damping factor of 200 will be reduced to 47 (8 Ohms) when using a 10 m long, 2.5 mm²
speaker cable. The power loss at 8 Ohms is 1.63 %, at 4 Ohms 3.25 % and at 2 Ohms even 6.5 %.
The maximum cable length is 30 meters!
Installing the speaker-cables
Connect the speaker-systems among each other using the inputs and outputs. Connect the cable of the first
speaker-system with the Speaker-socket of the amplifier. The signal will be transmitted to the individual
speaker-systems.
Always treat the cables carefully and protect them from damages during transportation.
Install the cables always in a structured way and protect them from damage.
The cables must be installed in a way that no person can stumble over them. Always fix the cables with an
appropriate tape.
Both cables should be of the same kind.
Both cables should have the same length.
Both cables should be installed directly (no loops, S-shaped overlengths)
Always install the cables far away from power cables (never closely parallel)
Never put heavy objects like speaker-systems, flightcases etc. on cables.
Never wind up cables tightly around the elbow, but rather sleek with an interior diameter of 20 to 30 cm.
