Procedure:
Step 1:
Saw out a mounting hole with the correct mounting dimensions (see chapter Technical
Specifications)
Step 2:
Make the electrical connection (section
4.3
).
Step 3:
Remove the protective grille.
Step 4:
Insert the speaker into the ceiling, and fix the speaker cabinet by tightening the mounting screws.
Insert the protective grille again.
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. An incorrect
matching may damage the PA amplifier.
Before starting with the installation, you must clarify how many speakers you would like to install in the room.
4.3 Electrical connection
DANGER TO LIFE!
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 via two of the cables to the 100 V output of the PA amplifier: Use the blue
core COM (negative pole) and, according to the desired power rating one of the other colored
cores
(see table in chapter Technical Specifications).
Step 3:
When connecting several speakers, make sure that all speakers have the same polarity and that
the amplifier is not overloaded.
5. OPERATION
Switch on the amplifier. Adjust the volume with the volume control.
Always make shure that the output signal is not distorted and that your speaker 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.
