a simplified, and inexpensive phase lock loop module featuring only an input, output and a single modulation input, combined with a frequency knob to control the locking frequency and a depth knob to provide
attenuation to the modulation input (which modulates the frequency). sensitive to both amplitude and wave shape on the input for various effects and degrees of locking. the modulation input responds only to
positive voltages, negative voltages are ignored.
analog signal path.
ac coupled for audio use.
high quality tht components including aluminum knobs and panel with metalphoto graphics, alpha potentiometers, switchcraft jacks, and through hole plated pcb.
