DPU DIGITAL PATCHING UNIT FOR NXAMP
while booting up; it should be LOAD3_11 or above.
After a few second the current selected speakers on the NXAMP are routed inside the DPU
and their names are displayed on the DPU screens.
DPU front panel connectors routing
The front panel of the DPU is very symmetrical and shows two groups (one on grey
background, the other one on black background), each with two SPK4 and one SPK8.
For each of these blocks, the internal routing of SPK4 and SPK8 is done like on the bellow
picture.
This means that SPK4 and SPK8 are always connected (hardwired) in parallel. In most of
the cases, only one of this plug kind will be used at a time, but this parallel wiring can be
useful to carry two SPK4 outputs over a SPK8 long cable for example (with breakout box at
the other end) or to link several amplifier together (see further in this manual).
Or course the routing from the amplifier output to these front panel connectors is done
dynamically regarding the combination of four speakers’ setups done into the NXAMP.
DPU displayed information
Two next speakON® (one SPK4 and one SPK8) will share the same LCD display. In case of
SPK4 output, the displays will indicate some information regarding the following pinout:
Now if SPK8 output shall be used, the displays will indicate some information regarding the
following pinout:
Of course same rules apply to the next set of front panel connectors.
