Specifying A Reference Clock - Roland V-800HD MK II Owner's Manual

Specifying a Reference Clock

You can specify a clock to which operation of the V-800HD MK II is
referenced (a reference clock).
NOTE
Video output from the SD OUT connector is referenced to the
V-800HD MK II's internal clock irrespective of the reference-clock
setting.
1.
Select the [MENU] button g "System" g "Reference."
2.
Use the [VALUE] knob to specify the reference clock.
Value Explanation
