sorry...i said i believed you said fix, i accidently deleted the post before responding...

so now i say it's not a solution, it's a work around...it doesn't deal with the noise of the phase shifter, it masks it...

yes, but noise is common in phasers...

1200ma powersupply from A100p to drive Roland System 100m modules

Has anyone tried anything like this with a 1200ma A100p


thanks Dave

Should you manage to get hold of a module but haven't a rack to power  
it, there is a solution. If you can handle a soldering iron, then  
something like the Maplin +/-15v (100ma) PSU should suffice (part  
number LP88V). You need to make up a lead with an 8-pin DIN plug  
(part number FJ91Y -- see connections list below) at one end to  
supply the module. Warning! Don't attempt to connect a 100M module to  
anything other than a Roland rack unless you are confident that you  
won't damage the module with an incorrectly wired plug or PSU.  
Mistakes can be expensive.

System 100M 8-pin DIN plug connections are as follows:

� Pin 1 PSU +5v
� Pin 2 gate
� Pin 3 no pin
� Pin 4 LED +
� Pin 5 Trigger
� Pin 6 PSU -15v
� Pin 7 PSU ground
� Pin 8 CV
� Pin 9 LED ground

While we're on the subject, here are the connections for the 6-pin  
leads that link 100M racks to other racks or keyboards; use Maplin  
part number HH29G for the 6-pin plug. If you're linking racks, don't  
connect pins 1 and 2, but use all pins when connecting a 100M keyboard.

� Pin 1 PSU -15v
� Pin 2 PSU +15v
� Pin 3 gate
� Pin 4 trigger
� Pin 5 PSU ground
� Pin 6 CV

Hi Dave,

The 100m modules use +/-15V for the critical circuits and a separate
+22V (unregulated) line for the LEDs. The Doepfer supplies are a
straight +/-12V and are hence not compatible with the 100m Modules.
You would need to modify the supply (and probably use a different
transformer) in order for this to work. I reckon you would be better
off building a PSU Kit to do this. You can Email me if you want me to
point you to some good PSU designs.

Cheers,
Adam-V

Roland's system 100M runs with +/-15V !
