The Pedal - Schippmann ebbe und flut User Manual

9.6 The pedal

A passive or active volume pedal can be connected via stereo-cabel to the rearpanel socket
"PEDAL" (5).
TIP/RING of socket (5) provides +5 Volts via an 1.2 kOhm resistor.
The respectively other pin of the stereo socket RING/TIP feeds back the pedal-controllable +5 Volts.
back: (3) [POLARITY]
TIP and RING at socket (5) can be exchanged with the rearpanel switch (3) in order to adapt to diffe-
rent brands.
When used e.g. a Roland-pedal EV-5/ FV-60, the left position of the switch (3) would be correct.
Fig. 9.6.1 shows the cicuitry of socket (5) depending on the position of the polarity switch (3).

Next to the pedal functionality, the +5 Volts can be connected to e.g. external potentiometers in order
to feed them back to the CV-inputs.
The remaining pin of socket (5) can be used as a CV-input, in order to modulate the filters indepen-
dently.
This input is limitted to 30 Hz and thus unusable for audio or fast modulations.
