Doepfer A-143-3 Quad LFO shure The logical states of the

The logical states of the inputs ("1" = high / "0" = low) are linked together in 3 ways: AND

The transformer also helps eliminate hum and buzz caused by ground loops by isolating the input from the output

according to DIN/IEC 651

The frequency dividers of the 4 subharmonics is adjusted with up/down buttons as displayed with 2 character LED displays

Doepfer A-143-3 Quad LFO shure The logical states of theModule A 143 3 is a low cost four fold modulation oscillator, often called LFO (low frequency oscillator). Like the other modules of the A 143 series (A 143 1 and A 143 2) not a very "exciting" module, just a bread and butter device and a simple demon for work. The module contains four simple LFOs. Each LFO is equipped with three waveform outputs: triangle, rectangle and rising sawtooth. The frequency of the sawtooth output is twice the frequency of
