DOEPFER A-143-4 QUAD VCLFO - VCO

Module A-143-4 is a fourfold voltage controlled low frequency oscillator (LFO). As the frequency range includes moderate audio frequencies it can be used as a four-fold VCO too. four independent VCLFOs/VCOs with triangle core frequency range switches: low (bottom position) = LFO mode, high (top position) = VCO mode two frequency control CV inputs for each unit CV1 without attenuator (~ 1V/oct) CV2 with attenuator manual frequency control internal jumpers for the frequency range of the manual frequency controls: jumper not installed: ~ +/- 1 octave range (mainly for VCO applications) jumper installed: ~ +/- 5 octaves range (mainly for VCLFO applications) Sync inputs: combined Reset/Direction inputs for unit #1 - #3 separate Reset and Direction inputs for unit #4 (normalled sockets, i.e. Reset is connected to Direction if the Direction socket is unused) up/both/down direction switch for unit #4, for technical details concerning the Reset and Directi
