5.Ipalmod Without Dpc Interface Board; 6.Installing An Optional Dsp Simm Board - powersoft IpalMod User Manual

11 : 5.IpalMod without DPC interface board

The IpalMod amplifier module can operate standalone,
i.e. without the optional DPC interface board.
In order for the IpalMod to function without a connected
interface board, the CN102 Micro Match connector on the
control board must be patched:
short circuit pins number 8 and 17 on CN102.
FIGURE 14: CN102 patch.
The patch disables the reading of the attenuator knob on
the missing interface board, in order to set no attenuation
to the signal.

11 : 6.Installing an optional DSP SIMM board

The IpalMod amplifier module can host an optional DSP
board such as the Powersoft DSP-D and DSP-4 interfaces,
as well as any other custom interface. Refer to
for proper SIMM board dimensions and connectivity.
In order to route the signal path to the optional
DSP board on the CN8 connector remove the
jumpers from CN17 as shown in
Remove jumper to activate signal
routing to the SIMM connector CN8
FIGURE 15: Jumper settings for optional DSP board.
Note about Powersoft DSP-D/DSP-C boards. Since the
Powersoft DSP-D and DSP-C boards implement an input
volume potentiometer on the interface panel, remove both
jumpers from the CN17 connector (ref.
Remove both jumpers to activate signal
routing to DSP-C and DSP-D boards
