Operation; Connection With The Mains; Cleaning And Maintenance - Omnitronic AZ-212A User Manual

OPERATION

Make sure that the available voltage is not higher than stated on the voltage selector before you connect the
power cord.

Connection with the mains

Connect the device to the mains with the power plug.
The occupation of the connection cables is as follows:
Cable Pin
Brown Live
Blue Neutral
Yellow/Green Earth
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.
Switch the device on. After switching on the speaker-system, wait 8 to 10 seconds until you turn the volume-
control in order to avoid speaker-damage.
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
distortions 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 speaker-system first in order to avoid acoustic shocks
on the speakers.

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 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.
4) If the speaker-system is installed overhead, the inspection must include if the eye-bolts are still well
tightened. Otherwise the eye-bolts have to be tightened handtight again.
5) If the speaker-system is secured via clamping belts, the inspection must include if the clamping belts are
still well fixed. Otherwise fix clamping belts again.
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 serviceable parts inside the speaker system. Maintenance and service operations are only to
be carried out by authorized dealers.
