7.3 Overview
The following figures provide a brief overview about the audio- and modulation-structure, as well as
the signalflow of 'ebbe und flut' . White labeling means functions to be found on the frontpanel, dark
grey labeling to be found on the rear panel. Digits in brackets mean the number of the corresponding
knob, switch or socket. A letter in postposition means the corresponding pin of a stereo socket (t = TIP,
r = RING). Light grey labeling underlines internal signals, which are useful for understanding the units
functionality. Light grey labeling, used at the same term on different positions, means an internal con-
nection between these points, e.g. all in- and outputs of all modules which use the light grey labeling
"DYN", are internally connected with each other.
