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 Output-socket of the mixer. 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, flightcased etc. on cables.
Never wind up cables tightly around the elbow, but rather sleek with an interior diameter of 20 to 30 cm.
7. OPERATION
After having connected your amplifier to the mains, turn both gain controls counter-clockwise to Min-position.
The last device to be switched on is the amplifier. The "ON" and "PROTECT" LED light up now. If it does not,
check if the amplifier is connected to the mains correctly.
After the turn-on delay the speakers are activated (PROTECT-LED is off).
After having set the volume controls of the pre-amplifier in null-position, turn the gain controls of your
amplifier to mid-position. You must not hear any loud humming. If there is humming nevertheless, check the
connecting cables between the pre-amplifier and the amplifier (switch off components before). Now adjust
the volume with the gain controls CH-1 and CH-2.
Caution! Increase the level of each channel only so far that the CLIP-LED lights up shortly. Thus, you avoid
that the output signal is distorted and your speakers are damaged.
When operating the speaker-system, please make sure that the loudspeakers always sound well. When
distorsions can be heard, either the amplifier or the loudspeaker is overloaded. Overloads can quickly lead to
amplifier or speaker damage.
In order to avoid damage, please reduce the volume immediately when distortions can be heard. When
speaker-systems are destroyed by overload, the guarantee becomes void.
Always check the sound pressure level with a meter in order to keep to the threshold.
If you want to switch off the system, switch off the amplifier first and then the pre-amplifiers in order to
avoid acoustic shocks on the speakers.
8. CLEANING AND MAINTENANCE
The operator has to make sure that safety-relating and machine-technical installations are inspected by an
expert after every four years in the course of an acceptance test.
The operator has to make sure that safety-relating and machine-technical installations are inspected by a
skilled person once a year.
The following points have to be considered during the inspection:
1) All screws used for installing the speaker-systems or parts of the speaker-system have to be tighly
connected and must not be corroded.
2) There must not be any deformations on housings, fixations and installation spots (ceiling, suspension,
trussing).

3) The electric power supply cables must not show any damages, material fatigue (e.g. porous cables) or
sediments. Further instructions depending on the installation spot and usage have to be adhered by a
skilled installer and any safety problems have to be removed.
We recommend a frequent cleaning of the speaker-system. Please use a soft lint-free and moistened cloth.
Never use alcohol or solvents!
There are no servicable parts inside the speaker-system. Maintenance and service operations are only to be
carried out by authorized dealers.
If the speaker-system distorts, one of the loudspeakers may be defective. Test the speaker-system once
more with another amplifier. If the sound remains distortet, the speaker-systeem should not be operated any
more in order to prevent further damage. Please contact your dealer.
If clacking sounds are heard from the speaker-system, screws may have loosended due to the continuous
vibrations. The speaker-system should be checked by a specialist. Especially for public use, the speaker-
system should be checked before every operation so that the speaker-system and the speakers in the
systems are always well fixed.
Should you need any spare parts, please use genuine parts.
Should you have further questions, please contact your dealer.
