INSTALLATION
Attachment
Before attaching the speaker, make sure that the installation area can hold a
minimum point load of 5 times the speaker's weight. The device must only be
installed at a vibration-free, oscilation-free and fire-resistant location. Please refer
to the instructions under Operating Determinations.
Procedure:
Step 1: Saw out a mounting hole with the correct mounting dimensions (see
chapter Technical Specifications)
Step 2: Make the electrical connection.
Step 3: Bend the mounting springs upward up to the stop and keep them in
this position.
Step 4: Insert the springs into the mounting cutout and let the speaker slide
carefully into the cutout for a flush fitting.
Choosing an Appropriate Amplifier
This speaker must only be connected with an appropriate 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.
Electrical Connection
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:
Step 1: If the PA system is turned on, turn it off before making any connection.
Step 2: Connect the speaker via two of cables to the 100 V output of the PA amplifier: Use the black
cable COM (negative pole) and, according to the desired power rating, either the green core for
3 W or the white core for 6 W.
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.
Notes Regarding Operation
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.
DANGER TO LIFE!
High voltage at terminals. Installation by skilled personnel only.
Turn off PA system before connecting.
