190-2 Strange behavier?

190-2 Strange behavier?

2013-03-04 by Syndromeda

I have reassembled my Doepfer modular and now I have a strange behavier with one of my two A-190-2's.
I only have about 4 octaves of CV.
When I choose C1 as reference it goes from A1 to C6, when I choose C0 it goes from C1 to C5. I do not have this behavier with my other A-190-2, even not when I swap them.
The strange behavier also lasts when I use the outher Gate / CV pins instead of the internal connection.
Anybody have a clue?
TIA,
Danny

Pay attention that only ONE transmitter for CV and Gate is allowed on each
bus board. Maybe this causes the limited CV problem. Remove the
corresponding jumper on the A-190-2 module and use the front panel jacks to
be on the safe side. Otherwise please return the module for repair to the
dealer where you purchased the unit.

Thanks for the fast answer Dieter, but the 190-2's are in independent cases - no connections.
If I turn up the VCA gain until I hear a constant audible sound I can hear it is responding to the whole frequency range.

Sorry - but I have problems to understand the issue. Do you mean that the
full 5 octave range of the A-190-2 is covered when you open the VCA ?

Hi,
Yes, that's exactly what I meant. But I've solved the problem.
In my upper row, the VCO's were located as was the ADSR, in the lower row the 190-2. I had connected the two rows (bus boards) with that small Gate/CV cable and that did not worked, as I described before.
Now I have also put the 190-2 in the upper row, disconnected the cable and the behavier is back normal.
So it obvious had something to do with splitting up signals over two rows (bus boards).
Thanks anyway but everything seems normal now, only the modules are not in a place were I liked to have them.

Cheers,

When you use the CV/Gate cable you connect the CV and Gate lines of both bus
boards. It's the same as if both modules were on the same bus boards (i.e.
you short the CV and Gate of both modules if they are connected to two bus
boards which are connected by means of the CV/Gate cable).

For details please refer to the technical details
www.doepfer.de/a100_man/a100t_e.htm (chapter "Power supply and System Bus").
Here you find some remarks concerning the usage of the internal CV and Gate
lines of the A-100 bus.
