Doepfer - A-143-4: Quad VCLFO/VCO

Manufacturer Description: 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.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 corefrequency range switches: low (bottom position) = lfo mode, high (top position) = vco modetwo frequency control cv inputs for each unitcv1 without attenuator (~ 1v/oct)cv2 with attenuatormanual frequency controlinternal 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 - #3separate reset and direction inputs for unit #4 (normalled sockets, i.e. reset is con
