Choosing An Appropriate Pa Amplifier; Electrical Connection; Operation; Cleaning And Maintenance - Omnitronic GCA-516S Bedienungsanleitung

4.2 Choosing an appropriate PA amplifier

This speaker must only be connected with an appropriate PA amplifier. Observe the correct power matching.
The total load presented to the amplifier must not exceed the rated output of the amplifier. Before starting
with the installation, you must clarify how many speakers you would like to install in the room.

4.3 Electrical connection

High voltage at terminals. Installation by skilled personnel only! Turn off PA system before connecting.
Cabling a PA system is an electric installation which must only be carried out by a qualified electrician!
Always insulate the connection cables which are not used. Pay attention to the correct power matching.
Overload will result in damage of the PA amplifier and of the speaker.
Procedure:
Step 1: If the PA system is turned on, turn it off before making any connection.
Step 2: Connect the speaker to the 100 V output of the PA amplifier. Connect the black core (negative
pole) and the red core (positive pole) to the output of the amplifier.
Step 3: Alternatively it is possible to connect the speaker to a low-impedance amplifier output.
Step 4: When connecting several speakers, make sure that all speakers have the same polarity and that
the amplifier is not overloaded.
Step 5: Adjust the rotary switch to the desired power rating for the 100 V operation or select the position
THRU (8 Ω), for directly operating the speaker at a low-impedance amplifier output.

5. OPERATION

Switch on the amplifier and adjust the volume. Always make sure that the output signal is not distorted and
that your speakers will not get damaged.
During operation, please make sure the speaker always sounds well. When distortions can be heard, either
the amplifier or the speaker 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
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.

6. 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.
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.
If the speaker system distorts, it may be defective. Test the speaker system once more with another
amplifier. If the sound remains distorted, the speaker system should not be operated any more in order to
prevent further damage. Please contact your dealer.
Should you have further questions, please contact your dealer.
DANGER TO LIFE!
