A-101-6 Opto FET VCF jumpers

A-101-6 Opto FET VCF jumpers

2018-10-29 by rigo.schoeters@yahoo.com

Just a quick question about the "jumper for feedback insert" mentioned in http://www.doepfer.de/a100_man/A101_6_Jumper.pdf ... aren't those the exact same signals as on FB Out and FB In ?

I am looking to make a module with switches for the different modes (separate switches for each stage, unless somebody tells me that makes no sense) and as wondering if I should include 2 sockets for that feedback jumper.


And thank you for updating the New/Future modules page.

That's correct. The lower pin is connected to FB Out and the switching
contact of FB In.

The original version of the A-101-6 included a lot of voltage controlled
switches that were used instead of the jumpers (still mentioned on the
A-101-6 info page). But as this feature would have nearly doubled the priced
of the module we decided to use jumpers instead of the VC switches.

A few more planned modules will be added to the new/future modules page
during the next few days (e.g. A-180-4 quad buffer, A-135-2 slim version of
the voltage controlled mixer, A-197-3 controller module for RGB LED stripes
and some more).
