GENERAL DESCRIPTIONNote the symmetrical structure between channel 1 and 2 on one hand and channel 3 and 4on the other hand.When using the <strong>NXAMP</strong>4x1 Powered TDcontroller in bridge mode, here is the output routing:Now amplifier channel 1 and 2 works together in bridge mode (channel 2 is marked“Bridge” above). This is same for channel 3 and 4. The pin-out on the speakon is the sameas the channel 1 and 3 in non bridge mode, thanks to the programmable routing unit (notdrawn here).You can see with the dashed line on the above drawing that unused pins onoutput speakon are shorted together, but are not connected to ground. Therefore becareful as very high voltage might be present on these unused pins.User interface blockThe user interface block has already been described through the front panel description inthe first part of this document. Please note that all the commands and displays areavailable through the ESmonitor software by Auvitran, through the Ethersound network(except the mains switch).Communication blockThe communication block regroups the RS232 port (on a sub-D9 plug) and the GPIO port(on a sub-D25 plug).The RS232 port is mainly used to upgrade the firmware of the unit from a PC computer.But it could also be used in the future for local communication with other equipments.
