Connection panels

The LA4X rear side features three panels for audio and network cabling, see Figure 7:
 SPEAKER to connect loudspeakers.
 SIGNAL to connect analog and/or digital (AES/EBU or S/PDIF) audio sources and link the signals to another
amplified controller.
 L-NET to connect to a network and be remote controlled from LA NETWORK MANAGER software.
The XLR connectors of the SIGNAL panel can transport analog or digital signals depending on the input mode selected
by the user for channel pairs AB and CD (the two selections can be different). The devices to connect to the IN
connectors are given in the following table (see also section 4.9.1 for input mode selection):

Each LINK connector is wired to the corresponding IN connector and, thus, transports the same type of signal.
