How To Connect a DigiMod
1000NPS to a DigiMod
500/1000/1000 IS
1 Introduction
1.1 Preliminary considerations
The DigiMod 1000NPS is an exact replica of the DigiMod 1000 output stage (2-channel bridgeable, 2x500W on 4Ω, 1x1000W on 8Ω),
which can be used in combination with DigiMod 500/1000/1000 IS to extend the range of possible multi-channel congurations and power
3-way active loudspeakers. In order to make this connection possible, the DigiMod 1000NPS must be equipped with an optional DSP-C
board.

1.2 Tools Needed:
▶1 male MOLEX 3-pin connector
▶1 female MOLEX 3-pin connector
▶1 male PHOENIX 5-pin connector (MSTB, 2.5/5-ST-5.08)
▶Balanced cable (low impedance)
▶Soldering iron and solder
▶Powersoft CB000098 cable or equivalent (10 pole 8/10 mm cable, with 2 MOLEX Micro-Fit 3.0 connectors)
▶pliers for electronic use

2.2 Master or Slave
Powersoft recommends using the module with a DSP on board as master module, while the module without a DSP should be used as a
slave1. In this particular case, the DigiMod 1000NPS will act as master module with its on board DSP, while the DigiMod 500/1000 will be
the slave module. DigiMod 1000 IS modules come equipped with a DSP board that must be removed in order to congure the module as
a slave module.
The onboard DSP has 4 outputs:
Channels 1 and 2 output directly from the DSP board. These two channels could be used, for example, to drive the rst two ways of a three
way system.
Channels 3 and 4 are used to carry the input signal over to the DigiMod 500/1000/1000 IS slave module through a MOLEX connector on
the DSP board itself. The DigiMod 500/1000/1000 IS will therefore receive channels 3 and 4 as input. In this conguration, the slave module’s

output can be used, for example, in a bridged conguration to drive a subwoofer requiring more power.
2.3 How To Set Master And Slave Modules
Locate the jumpers on the modules
To set the module with DSP as MASTER: remove the jumpers in the pins BY22-BY33 in CN18 and BY31-BY21 in CN17 (the innermost
jumpers). Use pliers to aid in the removal (see Section FIGURE 5)
To set the other module (the one without DSP) as SLAVE: leave the jumper conguration as factory set.

3.3 Connecting the DigiMod 1000NPS To The DigiMod 500/1000/1000 IS
In order to connect the master module’s output channels (DigiMod 1000NPS) 3 and 4 from the DSP so they become inputs for the DigiMod
500/1000/1000 IS:
1. Remove the DSP from the DigiMod 1000NPS module
2. Take the male MOLEX 3-pin connector and solder this connector in the DSP board as seen in the picture below2
2Some DSP modules are equipped with a MOLEX connector at production time

3. Make the following cable so it connects DSP output channels 3 and 4 from the MOLEX connector to the DigiMod 1000NPS Phoenix
inputs. The cable will be balanced, low impedance and will have the following connectors:
▶1 3-pin female MOLEX
▶2 5-pin male Phoenix
4. Use the gure below as a connector pin soldering diagram.

In case of ground loop problems, remove the GND wire connection in the cable.
In order to connect the master module outputs to the slave module inputs:
1. Connect the cable that you’ve just made to the DSP in the DigiMod 1000NPS master module (with the MOLEX 3-pin connector).
2. Connect the other end of the cable with its two Phoenix 5-pin connectors to the slave module’s input connectors as seen in the gure
below:
