INSTALLATION
1) Saw out a mounting hole with the correct mounting dimensions (see chapter Technical Specifications)
2) Make the electrical connection (see chapter below).
3) Pull out the protective grille.
4) Insert the speaker into the ceiling and clamp on the enclosure by tightening the four mounting screws.
Replace the protective grille.

CONNECTION
Observe the load of the PA amplifier by the speakers. An overload may damage the amplifier! The total
power of all speakers connected must not exceed the amplifier power. When connecting multiple speakers in
parallel to a power amplifier, it is especially important to consider the correct polarity and the amplifier’s
minimum impedance. Please refer to skilled personnel if you are not familiar with the connection of multiple
speakers.
1) If the PA system is turned on, turn it off before making any connection.
2) Connect the speaker to the amplifier output with suitable speaker cables. It is possible to connect both
coils either in parallel or in series. When connected in parallel, the total impedance is halved to 4 Ω.
When connected in series, the total impedance doubled to 16 Ω.
3) A crossover is required for system integration.
