The FoN knob is an attenuverter. The output level from this attenuverter can be seen on the LED along the

red lines after the knob. Green for positive and red for negative voltages.

This output is max +/- 5V and can be used as an audio source or a gate signal.

If the FoN LED isn't flashing the folder has stopped in an on or off state and will output a DC voltage. Can be

useful when used with control voltages as a DC offset on the output.

The output of FoP is normaled to OUT via the main out volume control.

Lim/0/Dist

There are two different distortion alternatives on the output. It is not just two versions of the same distortion,

it is two completely different circuits that is being switched in.

The options are:

No distortion. Clean signal amplification trough the module is maximum one times with the orange out

volume knob set to full.

Lim

A non transparent limiting like distortion. In this case amplification of the orange out volume knob is

maximum 5 times. This gives the possibility to drive signals a bit in to the Lim distortion. The signal level is

then compressed via the Lim distortion.

Dist

A fuzz like distortion. In this case amplification of the orange out volume knob is maximum 20 times. This

gives the possibility to drive signals hard in to the Dist distortion. The signal level is then compressed via the

Dist distortion.

Expander E-1

As an option the E-1 expander can be used to control Lim and Dist on and off via external control signals or

audio rate signals. A positive signal of 1V or more will turn the distortion on.

The Lim/0/Dist switch on the Wavefolder overrides signals put in to the Lim and Dist jacks on the E-1.

This means that you can for instance have a audio signal in on the Dist jack on the E-1 modulating the output

at audio rate and freeze it on with the switch.

An other application could be attaching the Lim and Dist jacks on the E-1 to a sequencer and use it to get

two types of accent to notes played.
