Sopot

1980 Triple Signal Summator

Sopot is a compact utility module handy when the need arises to sum multiple stereo and mono sound sources (up to four signals for each section). It is a triple summing mixer featuring three signal adding sections with the middle one optionally fed to the top and bottom ones. The contribution of the middle section is switchable between 0%, 50%, and 100%. Each of the summing sections is built with high quality audio opamps and features a soft clipping circuit for nice saturation. Gain can be optionally reduced to -12dB in order to allow summing of hot signals.
