Choosing appropriate connection cables
The speaker-system must only be connected via a sufficiently dimensioned cable. Too thin cables lead to
cable heatup or enormous power loss and loss in sound-quality.
For all speaker-systems up to 400 Watts, we recommend a cable diameter of 2.5 mm², for all other speaker-
cables 4 mm².
A high damping factor of your amplifier supplies a clear sound reproduction. Unnecessarily long and thin
cables will influence the damping factor and thus the low frequencies in a negative way. In order to
safeguard good sound quality, the damping factor should lie around 50. The longer a cable has to be, the
thicker it should be.
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!
Connections
Your speaker-system is equipped with 4-pole, lockable Speaker-sockets. For locking the connection turn the
plug to the right. For unlocking pull the unlock button and turn the plug to the left and pull it out of the socket.

INSTALLATION
This speaker-system must only be installed at a solid, plane, anti-slip, vibration-free, oscilation-free and fire-
resistant location.
Before installing the system, make sure that the installation area can hold a minimum point load of 5 times
the system's load (e.g. weight 20 kg - point load 100 kg).
The speaker-system must never be installed higher than 100 cm without secondary attachment.
Install the desired number of speaker-systems in the room.
Every speaker-system features two transportation handles. The speaker-system should be carried without
force by two persons of the same size. Carrying the speaker-system as one person alone should be avoided
as the high weight and the strain could lead to back damages and torsions. Please note that all speaker-
systems with more than 25 kg weight must be transported with two persons.
Installing and orienting the speaker-system
When installing the speaker-system on e.g. a stage, microphones and turntables should always be located
behind the speaker-systems. In this way, you can avoid dangerous and unpleasant feedbacks. If you cannot
install the speaker-systems this way, the microphones and turntables should be located as far away as
