Step 1:
If the PA system is turned on, turn it off before making any connection.
Step 2:
Connect the left and the right channel of a PA amplifier to the input terminals L and R. Use
suitable speaker cables to connect each positive pole of the amplier to the red terminal and each
negative pole of the amplier to the black terminal.
Step 3:
The built-in crossover allows to directly connect CSA tops to the output terminals L and R.
Step 4:
When connecting several speakers, make sure that all speakers have the same polarity and that
the amplifier is not overloaded.
Information on speaker cables
• Speaker systems must only be connected via sufficiently dimensioned cables. Cables that are too thin 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 %.
• Both cables should be of the same kind and have the same length.
• The maximum cable length is 30 meters.
• Always treat cables carefully and protect them from damages during transportation.
• Install cables always in a structured way and protect them from damage.
• Cables must be installed in a way that no person can stumble over them. Always fix cables with an
appropriate tape.
• Cables should be installed directly (no loops, S-shaped overlengths).
• Always install cables far away from power cables (never closely parallel).
• Never put heavy objects like speaker systems, flightcases etc. on cables.
• Never operate cables wound up.
