⑨Footswitch Input
Input jack for external bypass (dry/wet) control, e.g. by a footswitch
•Switch closed: The dry original input signal (true bypass)
•Switch opened: The effect signal (also depending on postion of the "Bypass"
control knob )
The switching also can be controlled by an external logic signal (0V = effect , + V = dry),
e.g. a gate signal from a synthesizer.
To align the output amplitudes of the dry and wet signal, adjust the processed output
signal with 'Output Gain' trimmer .
⑩Oscillator Frequency High/Low Switch
Hi: ≈ 8Hz – 18000 Hz (Audio range)
Lo: ≈ 0.1 Hz – 60 Hz
In "Hi" position, the oscillator is mainly working in audio range. The amplitude modulation
will generate additional audio frequencies – sum and difference tones of the input signal
and the oscillator frequency.
In "Lo" position, the oscillator is working with subaudio frequencies. The amplitude
modulation result is a tremolo-like sound. Volume of the input signal will change
constantly with the oscillator frequency.
⑪Oscillator Frequency Control
Coarse adjustment of the amplitude modulation (AM) oscillator frequency.
⑫Oscillator Frequency Fine Adjustment Control
Fine tuning of the oscillation frequency. Range is about 4 – semitones (quarte).
⑬Oscillator Waveform Switch
The oscillator waveform can be selected between sinewave and triangle. In " " (sine)
position, the effect is a more smooth sound with less overtones; in " " (triangle) mode the
generated sounds are rougher and with more overtones.
⑭LFO Frequency Control
Speed control of the internal LFO (low frequency oscillator) for frequency modulation of
the ring modulation oscillator. Frequency is from ≈0.06Hz (left position ) to ≈ 44Hz (right
position)
The LFO frequency is also displayed by the orange LED for visual control.
⑮LFO Modulation Depth Control
Amount of LFO modulation depth
⑯LFO Waveform Switch
The LFO waveform can be selected between triangle (" ") and square (" ")." " will
provide a continously up-and down gliding pitch, while " " makes the oscillator shifting
between two tones.
⑰Envelope Follower/ext. CV Modulation Depth Control
The internal envelope follower converts the volume of the input signal on the instrument
input into a control voltage modulating the oscillator frequency. Amount of modulation
can be varied by this knob.
If the external frequency CV (= Control Voltage) input is used, the internal envelope
follower will be switched off; instead the signal on can be adjusted by this pot (frequency
modulation depth).
