Procedure:
Step 1:
Cut the ceiling tile to the correct dimensions.
Step 2:
Make the electrical connection (section
4.3
).
Step 3:
Place the speaker onto the ceiling grid with the support rail crossbar.
Step 4:
Drop in the ceiling tile.
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
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 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.
