hi list, its November now.... any nice modular patching ideas to share? modular knowledge to share and spread? best regards, Bakis. Bakis Sirros - Parallel Worlds / Interconnected / Memory Geist [Doepfer_a100] group owner www. parallel - worlds - music. com www. myspace. com/ par

Now why didn't I think of that :) I tried swapping all 4 chips from channel 3, No joy though. I'm guessing channel 3 and 4 chips are identical?!? Jonathan --- In Doepfer_a100@yahoogroups.com, Florian Anwander wrote: > > Hello > > if the chips are socketed, try swapping the chips

Hello if the chips are socketed, try swapping the chips of pcb 4 with other pcbs. I suspect 555 to be dead. TL082 usually survive wrong powersupply at 12V. Florian
2010-10-31 by Guy Drieghe D.
Jonathan, I don't have access to any of the modules you're referring too, but in general -- assuming they've been powered backwards, the first things to go are the electrolytic (or tantalum) caps near the power connector. Burn markings are most likely coming from those caps which

"on channel 4 light up and the output's seem to do nothing" I guess that's not quite true: http://soundcloud.com/user8805415/a-143-1-test In the above test: A-110 Saw -> VCA -> Record. A-143-1 ENV out (all four in turn) -> A-110 CV1 input. Jonathan --- In Doepfer_a100@yahoogroups

Having recently acquired a damaged A-136, I have now ended up with a damaged A-143-1. At least the Waveshaper was sold as damaged, the A-143-1 was sold as new :( Channel's 1, 2 and 3 seem fine. Neither of the two LED's on channel 4 light up and the output's seem to do nothing. I

Thanks for your help again Bakis Wherever I put the offset knob I can only ever get 4V from that point (e.g. offset set to -2V, 4V in I get a range of -2 to +2V out. Offset set to -4V, 4V in I get a range of -4 to 0 volts out). This is with att. set to fully clockwise (10 on the
2010-10-29 by Bakis Sirros
hi Rich, first of all: offset knob at '1' position (the 1 according to the scale that is marked on the module front panel) should give you -4 volts offset, not 0volts. now, the a183-2 module should give x2 amplification, according to specs... Dieter? Bakis Sirros - Parallel World
2010-10-29 by Bakis Sirros
the A183-2 is an attenuator/polarizer and offset generator.(and a x2 amplifier) so, you say you want to make a +4volts input into a +4 to -4volts output, right? so: you have set the JP3 jumper as dieter says (and now the offset knob gives you -5 to +5 volts offset), and have you
2010-10-29 by Richard Horsman
OK, so I bought one of these, moved the jumper but can't get the 2x amplification as mentioned here (http://www.doepfer.de/a1832.htm): "The amplification range for the input will be probably 0...+2 in the attenuator mode, and -2...+2 in the polarizer mode, i.e. the maximum amplif

Hi Bakis Like you say, I was expecting the attenuator knob to give me 0 to 2x amplification, but it gives only 0 to 1x. With offset at around 1 o'clock position (0V offset), +4V in, switch in attenuator mode and att. knob at 10 I get +v4V out. Rich --- In Doepfer_a100@yahoogroups

2010-10-28 by Bakis Sirros
ok, this is super obvious, but, anyway: why not have your S/H output random voltages in irregular timing too? so, connect your S/H source (say a vco triangle wave) into a comparator and connect the comparator output to the sync input of the vco (or the reset input of the a145 lfo

hi Duncan, some ideas: have you connected the AD5 correctly? (the red stripe down). have you connected all the modules correctly? (again ribbon's red stripe down on the busboard) do all 3 leds on the right of the busboard light up? (+12 volts, -12volts, +5volts) did you buy all t
