I got a reply which was quick, telling me that it's not made for CV and that I should be using an active mixer for that purpose.
Fair enough, shame that the product page on their website actually says "This simple passive mixer is suitable for mixing both audio and control voltage sources."...


Hi,
I recently ordered the Synthrotek Mix kit for eurorack and have successfully assembled it.
It seems to work, however I experience significant signal amplitude loss when patching CV through any of the 3 channels. It sorts of passes the signal to the output however compared to the input signal it's much weaker. Is this a known issue? The assembly is good and tested however I can't really use it for CV as intended.

Any ideas or experience with this module?
