then a setup with PS10R2/LS400/PS8/LS600 should be recalled.
Linking several DPU together
With some speakers setup it could be useful to link several DPU together. For example with
active setups, using NXAMP4x1 for HF and NXAMP4x4 for LF, or with GeoT setups,
requiring more than one NXAMP 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 display it means that the
corresponding pins on the associated speakON® connectors are floating. Thus it can be
feed with other DPU output.
The following example will show how to connect two DPU together to feed a speakON® 8
connector to a complete STM system (S118 + B112 + M46).
First NXAMP4x4 will run the setup number 67 of the LOAD3_15, running the STM in
stacked mode, feeding Main boxes M46 in active on two channels, and the STM bass box
B112 on two other bridged channels. The DPU outputs will then be:
Note that the 1+/1- pins of the first SPK4 are not connected to anything and that the
corresponding display line is empty.
Second NXAMP4x4 will run the setup number 72 of the LOAD3_15, meaning the S118 in
Omni mode.
Note that this time the 2+/2- pins on the first SPK4 are not used.
We will now use a SPK4 link cable to plug to link the first SPK4 output of the second DPU in
the first SPK4 output of the first DPU. Thus the S118 signal will be also available on the
SPK8, together with B112 and M46 allowing the user to have only one speakON® 8 cable
to feed up to 3 x S118, 3 x B112 and 3 x M46.
