A-126-DDF Dual Dome Filter

Dual Dome Filter with -45° and +45° Phase Shifted Output.

Based on the Doepfer Frequency Shifter A126-2 Dome Filter circuit. Nicely designed circuit board by Dieter Döpfer with an accurat and almost nearly 90° shift over the full audio spektrum. Friendly provided for my DIY Idea of an Dome Filter inside another Module for further frequency shift research or whatever might come out later.
