OffP

Offset for the positive folder. This is the threshold value for the positive folder. It can be set from -8V to +8V.

For audio signals OffP is mainly usable from its center position to fully clockwise. That is from 0 to +8V.

Setting the offset to negative voltages can be useful for manipulating control voltages.

Control voltage in to the attenuverter P controlling the positive wavefolders offset voltage.

This signal is added to the OffP level.

The LED close to the P knob shows the output voltage from the attenuverter. Green is positive and red is

negative voltage going to the Mod knob that controls the amount of folding.

OffN

Offset for the negative folder. This is the threshold value for the negative folder. It can be set from +8V to -8V.

For audio signals OffP is mainly usable from its center position to fully clockwise. That is from 0 to -8V.

Setting the offset to positive voltages can be useful for manipulating control voltages.

Control voltage in to the attenuverter N controlling the negative wavefolders offset voltage.

This signal is added to the OffN level.

The LED close to the N knob shows the output voltage from the attenuverter. Green is positive and red is

negative voltage going to the Mod knob that controls the amount of folding.

Mod

The amount of signal fed down to the main mix resulting in the folding effect together with the Clean signal.

Mod controls the volume of the folding signal from the sum of the positive and negative folder.

The LED below the Mod knob shows the output voltage going to the main out mix. Green is positive and red

is negative voltage.

Sym

The folding is done individually on the positive and the negative side of the incoming signal when the switch

is down. Asymmetrical mode.

Setting the switch to Sym makes the folders go symmetrically, folding equally from both the positive and

negative side of the incoming signal.

With this setting OffN is disconnected and the offset value for both sides are controlled via OffP.

The attenuverter signals coming from P and N are added together and sent to both the positive and negative

folder.

FoP

Folder Positive. The FoP signal is normally low, -5V. When the positive folder is active the FoP signal goes

high, +5V. You can see this on the LED next to the FoP knob.

The FoP 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.

FoN

Folder Negative. The FoN signal is normally low, -5V. When the positive folder is active the FoP signal goes

high, +5V. You can see this on the LED next to the FoN knob.
