Doepfer A-147-4v Dual Voltage-Controlled Low Frequency Oscillator
A-147-4 is a dual voltage controlled LFO, each with triangle, sine, rising & falling sawtooths, as well as rectangle waveforms. The pulsewidth of the rectangle can be controlled manually or modulated via control voltage. The waveforms are converted from a core triangle waveform. By means of a jumper the basic frequency range of each LFO can selected: about 0.02 Hz (~ 50 seconds) ... 2.5kHz or about 0.0017 Hz(~ 600 seconds) ... 220Hz. That way each LFO can be used also as a VCO with a max. frequency of about 2.5kHz. Each LFO features a reset input which can be used to reset the triangle signal.
