Back panel description
(1) Network outputs
These three RJ45 outputs are passively connected to the front panel Ethercon®
connectors. A great care has been taken in PCB design to ensure a minimum loss on the
signal path.
The network data will always flow from front panel to back panel of the DMU even if it is
not powered.
(2) Analog outputs
These four XLR-3 outputs are passively connected to the front panel XLR marked from A to
D. A great care has been taken in PCB design to minimize the distortion on the signal path.
The analog audio signal will always flow from the front panel to the back panel of the DMU
even if it is not powered.
(3) GPIO port
This GPIO port is intended to be connected to the NXAMP GPIO. Thus power supply (5
Volts) from the NXAMP will be fed to the unit and the view-meters data will also be
provided through the GPIO port.
You will need a straight DB25, male/male cable to connect the NXAMP to the DMU.
NB: A cable kit for DMU containing
1 2
3
• 4 x Neutrik XLR to XLR cords
• 3 x RJ45 links (a red, a green and a blue one).
• 1 x DB25 male/male straight cable
can be purchased from NEXO separately.
Operating the DPU
Using the DMU is straightforward, as there is nothing to set up. The only requirement is
that the NXAMP firmware supports the DMU, otherwise the view-meters won’t work
properly.
