Rec Run
Generator
Timecode runs while recording and is stationary
when not recording. In this mode, timecode
defaults to the last stationary value at power-up.
When switching to Record Run from another
mode, the internal generator will stop at the last
timecode value.
Free Run
Generator
Timecode runs continuously. Timecode continues
counting for up to two hours after power-down.
Free Run Auto Mute
Generator
Timecode runs continuously; however, timecode
output is muted during standby. This is useful for
triggering external devices when in free run time-
code work
fl
ows.
Free Run Jam Once
Generator
Allows the mixer to automatically jam to an ex-
ternal valid timecode source when
fi
rst connected.
Once jammed, the mixer will retain the timecode
count even when disconnected from external
source and for up to two hours after the mixer is
powered down.
24h Run
Generator
Timecode runs continuously with its value based
on the mixer’s time and date settings. This is use-
ful for work
fl
ows requiring timecode be referenced
to the Actual Time clock.
24h Run Auto Mute
Generator
Timecode runs continuously with its value based
on mixer’s time and date settings; however, time-
code output is muted during standby.
Ext-TC
Reader
Timecode is derived from external timecode
sources.
Ext-TC Auto-Rec
Reader
Timecode is based on external timecode sources,
and allows recording on the 688 to be triggered
via external timecode starting and stopping.
Ext-TC/Cont
Reader/
Generator
Timecode is based on external timecode sources.
If timecode is disconnected, the 688 continues
counting from the same value, using its internal
timecode generator. This is useful when working
with wireless timecode sources, allowing the mix-
er to free-wheel through wireless dropouts.
Ext-TC Auto-Rec/Cont Reader/
Generator
Timecode is based on external timecode sources,
and allows recording on the 688 to be triggered
via external timecode starting and stopping. Also,
if timecode is disconnected, the 688 continues
counting from the same value, using its internal
timecode generator. This is useful when work-
ing with wireless timecode sources, allowing the
mixer to free-wheel through wireless dropouts. In
the event of a dropout, the 688 will stop recording
when it receives a stationary value.
