Enhancements related to operation
It is now possible to control the Shift Lock switch (which
temporarily keeps [SHIFT] activated while it is not actually
pressed) without opening the System Parameter window
(VS-1680 Owner's Manual, p. 187).
Press [PLAY (DISPLAY)].
Hold down [SHIFT] and press [YES].
fig.6-30
Thereafter, each time you hold down [SHIFT] and press
[YES], Shift Lock can be toggled on/off.
When Shift Lock is OFF, the SHIFT indicator will light only
while you continue pressing [SHIFT]. When Shift Lock is
ON, the SHIFT indicator will light, or go out each time you
press [SHIFT]. [SHIFT] is active when the SHIFT indicator is
lit.
Direct current offset on the mix bus can be removed.
For example, in some cases the level meters of a device
(mixer etc.) connected to the output of the VS-1680 may
move even though no sound is being output. This is caused
by a direct current offset on the mix bus (MASTER output,
etc.). This component can be removed.
Press [PLAY (DISPLAY)].
Hold down [SHIFT] and press [F5 (SYSTEM)].
Make sure that the System menu is displayed. If not,
press [F6 (EXIT)].
Press [PAGE] so that [F2] indicates "GLOBL," and then
press [F2 (GLOBL)].
Use [ ][ ][ ][
"DC Cut," and use the TIME/VALUE dial to make the
setting.
If "DC Cut" is not shown, press [F2 (Prm2)], and use the
TIME/VALUE dial to make the setting.

When this is turned "On," any direct current offset on the
mix bus will be removed before output.
