VS-1680: Digital In Unlock Message
The VS-1680 allows you to record a digital signal from the external digital
audio equipment using the VS-1680s SPDIF or Optical digital inputs. When
recording from the digital audio equipment, you have to make sure that the
Master Clock parameter of the VS-1680 is switched to Digital In1 (when using
SPDIF input) or Digital IN2 (when using Optical input). There are a few reasons
why the display of the VS-1680 may show a dialog "Digital In Unlock!" and the
VS-1680 will prompt you to switch back to Internal clock:
1) Current VS-1680s song has a different sample rate than the sample rate of
the material you want to record. Please, check the sample rate of the material
you wish to record (if using DAT recorder - it is better to check the sample
rate while the material is being played) and create a new VS-1680 song with
matching sample rate, if needed.
2) The digital cable is damaged and needs a replacement. Try to replace the
digital cable you currently using on any other digital cable or even a regular
RCA audio cable for that matter.
3) The digital cable is not connected to the correct In and Out connectors.
Even if you are sure that you connected your digital cable to the correct In
and Out, check it again - you may be surprised!
4) Make sure, that the digital device you are recording from is capable of
transmitting Digital Word Clock as a part of its digital signal. Please,
contact the manufacturer of your digital audio equipment to verify this.
