The following article will guide you through syncing the VS-1680 to the VS-2400CD as well as passing digital audio from the VS-1680 into the VS-2400CD. This is useful if you would like to integrate two VS systems together or transfer tracks from an older VS system (e.g. VS-1680) into a new VS system (e.g. VS-2400CD).

Note: These instructions are no different for the VS-1680, VS-1880, or VS-1824.


  1. Connect the MIDI OUT jack of the VS-2400CD to the MIDI IN jack of the VS-1680.
  2. Connect the MIDI OUT jack of the VS-1680 to the MIDI IN jack of the VS-2400CD.
  3. Connect DIGITAL OUT jack of the VS-1680 to the DIGITAL IN (Coaxial or Optical) jack on the VS-2400CD. NOTE: Make sure that both the VS-1680 and VS-2400CD are powered on and that the current song’s sampling rate (48kHz, 44.1kHz, or 32kHz) is the same on both units.

Note: Use the CURSOR arrow buttons to move the cursor and then use the TIME/VALUE dial to change a setting in the following VS-2400CD and VS-1680 procedures.
