The D-LFO consists of two identical low frequency oscillators. The LFO2 can be internally sync-ed to LFO1 by an internal switch. The TRIP POINT control the voltage point at which the waveform is sync-ed; continuously from lowest to highest point of the waveform. Additionally the external signal can be used as sync source in two modes; the SYNC T converts the external signal to a very narrow pulse for a distinct sync and the SYNC G extract pulse width of the external signal for sync with a "steady state" sync-ed waveform. The RM/AM is a ring modulator / amplitude modulator. It is coupled to both LFO's outputs and has a separate output "RM-AM" and input for external signal (pre-patched to the LFO2's output).
