Hello


Which version of the A-131 is it To identify the version see
http://www.doepfer.de/a130.htm:
-------
Over the years three different versions of the module A-130 und A-131
have been manufactured:
Version 1:
The first versions of A-130 and A-131 were equipped with the Curtis
chips CEM3381/PA381 (A-130) and CEM3382 (A-131). These versions of
A-130/131 were not able to process slowly varying control voltages as
they had AC coupled signal in/outputs. They were manufactured until
about 2001.
Version 2:
The second versions of A-130 and A-131 were equipped with the OTA
circuit CA3080 and they were able to process even slowly varying control
voltages as they had DC coupled signal in/outputs. They were
manufactured from 2001 until March 2013.
Version 3:
Die latest versions of von A-130 and 131 are equipped with the high-end
VCA circuits SSM2164/V2164 (A-130) and THAT2159/V2159/SA2159 (A-131).
Even they are able to process slowly varying control voltages as they
have DC coupled signal in/outputs. These are manufactured since March 2013.
