CONNECTION OF LOUDSPEAKERS
IN THE CONFIGURATION WITH MULTIPLE LOUDSPEAKERS CONNECTED, THE SELECTOR SWITCHES ALSO CONTROL THE
"SLAVE" SPEAKER, EXCEPT FOR THE VOLUME, WHICH IS INDEPENDENT ON EACH SPEAKER.
- STAND-ALONE: using two standard Ethernet cables, connect the output of the first speaker (NETWORK OUT) to the input of the second
one (NETWORK IN) and the output of the second to the input of the first. Once you have chosen the amplifier that will act as communication
master, you must set the selector switch of the second speaker to position “PC/SLAVE”
- CONTROL FROM PC: the connection uses the RS485 protocol to send and receive data between the PC and speaker. The PC must be
connected via a USB cable to the USB-RS485 converter and from thence to the first speaker (NETWORK IN) using a standard Ethernet
cable. Connect the loudspeakers in succession with Ethernet cables (from NETWORK OUT to NETWORK IN) and place the relevant RJ45
bridge on the output of the last speaker.
The succession of the speakers, starting with the first one identifiable on the software as the speaker adjacent to the “FRAME”, must follow
the order of the system as designed on the PC.
The software does not currently support multiple interconnected systems; if multiple systems are installed, you must individually program
each one, one at a time (see “TAB NETWORK” section) of the LINE ARRAY MANAGEMENT SOFTWARE manual) .
Connection to the PC, besides the supplied converter (see page 19), requires the drivers necessary for the peripheral devices to function
properly. The drivers are available directly on the
website; to properly install the converter, refer to the instructions
