L-124 Harmonics LFO

Harmonics LFO

From top:
rate knob + CV input jack + rate LED
four level knobs for harmonics
output jack + 2 polarity LEDs

L-124 is sinusoidal LFO, rate range of fundamental is from over 5-minute period to 20Hz. Set of harmonics (2nd, 3rd, 4th, 5th -or- 2nd, 3rd, 5th, 7th, jumper selectable) can be added to fundamental frequency in ratios set by knobs. Jumper header set = 2345, removed = 2357. Rate knob works as attenuator for input CV if rate CV jack is plugged-in. Under about 1Hz (= slow rates) rate LED blinks dimmed/full brigthess to show LFO is still moving (output changes really slowly). Output level 10Vp-p (-5V to +5V), distortion of fundamental sine is under 0,2% (quite good for LFO).
