Connection with the mains
Finally connect the device to the mains with the supplied power supply cable. The occupation of the
connection cables is as follows:
Cable
Pin
International
Brown
Live
L
Blue
Neutral
N
Yellow/Green Earth
Attention!
The earth has to be connected! If the device will be directly connected with the local power
supply network, a disconnection switch with a minimum opening of 3 mm at every pole has to
be included in the permanent electrical installation. The
device must only be connected with an
electric installation carried out in compliance with the IEC standards. The electric installation
must be equipped with a Residual Current Device (RCD) with a maximum fault current of 30
mA.
6. OPERATION
1. Switch on the signal source connected.
2. Prior to switching on, turn the level control to the left stop position to avoid a possible switching-on noise.
3. Switch on the speaker system with the power switch. The power indicator lights up.
4. Adjust the desired volume with the volume control.
5. Adjust the sound with the controls HI (high frequencies) and LO (low frequencies).
6. During operation, please make sure the speaker always sounds well. When distortions can be heard,
either the subsequent unit or the speaker is overloaded. Overloads can quickly lead to damage on both
devices. In order to avoid damage, please reduce the volume immediately when distortions can be
heard. When speakers are destroyed by overload, the guarantee becomes void. Always check the sound
pressure level with a meter in order to keep to the threshold.
7. After operation, switch off the speaker system with the power switch. The power indicator goes off.
7. 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 devices or parts of the device have to be tightly 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.
Disconnect from mains before starting maintenance operation!
DANGER TO LIFE!
We recommend a frequent cleaning of the device. Please use a soft lint-free and moistened cloth. Never use
alcohol or solvents!
There are no serviceable parts inside the device except for the fuse. Maintenance and service operations are
only to be carried out by authorized dealers.
