Page 57: Operating The Dpu
• 2 x IEC mains cable with lockable connector (available with EU or US plugs) can be purchased from NEXO separately. OPERATING THE DPU Using the DPU is straightforward, as there is nothing to set up. The only requirement is that the NXAMPmk2 firmware supports the DPU, otherwise it will stay in Stand-by mode with nothing patched on its front panel connectors. -
Page 58: Dpu Displayed Information
This means that SPK4 and SPK8 are always connected (hardwired) in parallel. In most of the cases, only one of these plugs 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 amplifiers together (see further in this manual). -
Page 59: Unused Front Panel Connectors
The M3 cabinet can be connected using SPK8 only so it shows only arrow to this plug. Note that the M3 text is displayed on both lines because it is an active speaker using both 3+/3- pair and 4+/4- pair of the SPK8 connector. -
Page 60: Linking Several Dpu Together
LINKING SEVERAL DPU TOGETHER With some speaker’s setup it could be useful to link several DPUs together. For example, with active setups, using NXAMP4x1mk2 for HF and NXAMP4x2mk2 for LF, or with GeoT setups, requiring more than one NXAMPmk2 to feed all channels, or with STM to feed a four-way system using bridge amplifiers. Each time a DPU has nothing displayed on a line of one of its displays it means that the corresponding pins on the associated speakON connectors are floating. -
