Description

Doepfer's standard LFO: five waveforms at once over three frequency ranges, from one cycle every few minutes to the low audio range, with a reset input to start it in time.

Key features

  • Five outputs: inverted sawtooth, sawtooth, sine, triangle and square, about 8 Vpp
  • The two sawtooth outputs run at twice the frequency of the sine, triangle and square
  • Frequ. Range switch: L about 0.005 to 5 Hz, M about 0.1 to 50 Hz, H about 10 Hz to 4.5 kHz
  • Reset input: a rising edge sets the triangle to 0 V and restarts it on its rising slope
  • Two LEDs show the sawtooth and the sine / triangle frequency
  • Formerly called A-145
