Doepfer A-143-3 Eurorack Quad LFO Module

A workhorse for modulations with four identical simple LFOs oscillating between 1/30Hz and 4-5 kHz. Each LFO features a frequency control, a switch for the time range and outputs for triangle, rectangle and rising sawtooth.

Each LFO unit's frequency can be set coarse with a three-position switch and fine with a potentiometer. A red LED shows activity of the LFO.
Waveform-wise there are triangle, square and sawtooth with double frequency, all available at individual outputs.
