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 congurations 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 congure 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 conguration, the slave module’s

output can be used, for example, in a bridged conguration 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 conguration 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

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:
