The Doepfer A-143-9 Eurorack LFO-VCO Module is a powerful and competitively priced LFO/VCO synth module, featuring 2 frequency controlled inputs; CV1 without attenuator and CV2 with polarizer.

It is a voltage controlled sine LFO with 4 outputs. The phase shift between the outputs is 90 degrees. The sine shifted by 90 degrees is also called cosine, the sine shifted by 180 degrees is nothing but the inverted sine, and the sine by 90 degrees is nothing but the inverted cosine.

Two exponential frequency control inputs are available: CV1 without attenuator and CV2 with polarizer. Consequently the module can be used even as an experimental sine VCO but does not feature an exact 1V/oct CV input.

The main features of the Doepfer A-143-9 Eurorack LFO-VCO Module include:

• Eurorack LFO/VCO Module
• 2 Frequency Controlled Inputs - CV1 Without Attenuator & CV2 With Polarizer
• Dimensions: 40.3 x 50mm
