Analogue systems

Hi there.

I am new to this forum since I just got some AS modules to go on my 
Doepfer racks. I bought the modules used and I could not find any 
construction/interconnection details on the A.S. site.
I wanna ask which is the right way to connect the AS modules on the 
buss board? The RS110 has two red lines as well, one that is right 
on the edge and one that is 3-4 wires inside. The red line on the RS 
100 is not on the edge either. Any help please?
Can someone tell me the current requirements for the follwing 
modules?

RS 20
RS 80
RS 100
RS 110
RS 165
 
I think I might have overloaded one of my racks and there is no 
power going to the modules that are fitted on it (I think the +12V 
PSU is gone...).


Thank you in advance.

Peace out.

Do you have any of the custom doepfer -> AS cabling? They're 
ribbon cables cut up and crossed over to allow the right 
voltages to go to the right pins...

If you have these, it's pretty easy, just make sure 0v (red line) is 
towards the bottom on the doepfer bus side, and that it goes 
into the AS module on the pins marked 0v. That'll get the other 
pins lined up as well.

If you don't have these, STOP right now. You'll need to make 
them.

I don't have time to pull apart my doepfer system at the moment, 
but if you need some pics of the ones I've made, I can take a 
few at some point in the next few days. If you're handy with a 
multimeter and you're careful, you could probably suss it out 
yourself though.

But that's the key, BE CAREFUL. Sending the wrong voltages 
to your modules WILL fry sensitive ICs like 3080s, TL072s, and 
especially the BC transistors, I know from unfortunate 
experience!

First, you will need to get the Doepfer adapter cables, if you 
haven't already.
    Also, you have to orient the adapter cable correctly at both the 
module end and the Doepfer board end. ZTo do this, you must take note 
of thye markings on the AS PC board. On several modules, this means 
that the Adapter cable is pointing towards the front panel as it 
leaves the module and must be twisted backward to reach the bus board.
On all my AS modules, the ribbon cable's red line is on top of the 
cable as it leaves the module.
     When connecting the cable to the Doepfer bus board, the red line 
should be oriented just like it would for a Doepfer module. In all of 
my modules, this means that the cable must be twisted 180 degrees to 
orient properly with the Doepfer bus board.
    If you have no power to the modules in your rack, this probably 
means the AS modules are hooked up wrong.  Luckily, I had no damage 
to my system or my AS modules, even after repeatedly hooking them up 
wrong (doh!).  Nonetheless, this is probably not recomended.

hi nectarios,
if you want to connect AS modules to the AS psu board
all you have to take care of is to connect the red
stripe of the ribbon cable to the "0 volts"on the
module pcb and on the PSU pcb.now,if you want to
connect AS modules to the doepfer bussboard then you
will need special converter cables.i think analogue
systems or analogue solutions can supply these cables.
as for the power requirements:
rs20:10mA
rs80:25mA
rs100:30mA
rs110:45mA
rs165:5mA

btw,are you from greece???nectarios is a greek
name!:-)

Thanks Bakkis and shm. Yes Bakkis,I am from Greece, born and raised 
in Athens, but have been living in the UK for the last 4 years. I 
have checked my cables and they seem to do that twist to get the red 
line from top to bottom. My RS 110 module cable does not do that 
though, I'll check it out right after work to see if the red wire 
goes from 0V on the module to 0V on the buss board.

Thanks again people, much appreciated.

Peace out.

hi nectarie,
basically you'll need the converter cables!you must
check if you have them first!the AS cables and the
doepfer cables are NOT the same!!!!check this before
you destroy something!

Thanks guys, got it sorted!...well almost as I damaged the RS 110 
cable (broke one of the pins as I removed it...ordering another 
today). The RS 100 is a great filter and sounds harsher and more up-
front than the equivalent Doepfer A-120 Moog VCF. It overdrives more 
than the A-120 as well, but not more than the A-125 WASP filter 
which is the best for distortion...but the RS 100 sounds 
less "organic" than the A-120. The RS100 sounds even more different 
than the A-120 VCF when the resonance is cranked up. I'd say that I 
prefer the RS 100 when the resonance is high. Can't wait to get the 
RS 110 working!
The A.S. mixer and ring modulators are a bit less "hotter" than the 
Doepfer ones. The ring mods sound a bit different as well...I do not 
have a favourite one since they both sound great, but the sounds 
from the A.S. ring mod were a bit more interesting with slow PWM on 
square waves. I finally have a voltage controled LFO since the 
Doepfer ones I have did not have the frequency CV input, nor the 
ramp up/ramp down pot...weeeeee!

Thanks again.

Nectarios.
