    4. FUNCTION OF PANEL COMPONENTS “RATE CV” knob ① This is the Attenuverter for the CV signal input from the "IN CV" jack. VC DUAL DELAY ⑫ “RATE” knob ② This knob is adjusting the internal sampling rate of the internal delay circuit.
  • Page 7 “LO CUT” knob FB A FB B ⑤ This knob controls the cutoff frequency of the built-in -6 dB/Oct-sloped low cut �ilter, which is – along with the HI CUT in series - �iltering the output signal of Delay A before it´s fed back into the input of Delay circuit A (independent feedback loop for each delay circuit) or Delay B (crossfeedback mode) FEEDBACK dependent from the position of the feedback switch, and also routed to the...

    5. CHARACTERISTIC All audio · CV input signals are normalized (interconnected) from delay A to B. Conversely, when inputs A and B are performed using two cables, it is possible “Normalization” means that audio / CV signals are automatically duplicated to independently control and process Delay A and B (See FIG.
