EXAMPLES OF CONNECTION
Below are some examples of mixed combinations, to serve a wider area but with distributed power.
Please perform the installation of the required devices and connections to qualified service personnel.
In the case of use of several speakers used for audio paging in the same area or in adjacent areas,
remember the importance of making the connections of each loudspeaker by respecting its correct
polarity to make the intelligibility of the audio output as effective as possible.
(respect the connection of signal amplifiers and speakers so that they are in phase with each other)
