Frequency Modulator, Ring Modulator and Stutter.
modulating from slow tremolo up to vocoder like sound!
FUNCTIONS: ring modulator, frequency modulator, stutter
CONNECTIONS: audio input, audio output
SWITCHES: modulation on/off, modulation source in/out, frequency (vco) low/high, wave sinus/triangle, rectangular on/off.
POTENTIOMETERS: frequency (vco), modulation depth
VCO RANGE: Low range: 1Hz...300Hz, High Range: 100Hz...20kHz
IMPEDANCE: Input 30k, Output 2k
SUPPLY 12V stabilised, 30mA max.
Frequency control range: is set by P4. Turn P5 at lowest frequency and set P4 to maximum resistance. Switch frequency to high and turn P2 so that the oscillator signal appears at the output.
Turn now P3 slowly down until the oscillator stops, then turn it up until it starts reliably. Done.
Important! This depends on supply voltage, it must be stabilised, otherwise the DC setting drift and you'll need a re-adjustment of P2!
Carrier level: is set by P3 and P4(fine), turn P3 until the oscillator signal is no more present at the output, use P4 for fine adjustment.
