CHASE
The main function of this key is to enable or disable chase mode on the RADAR. When the
(TC PREF) key is pressed on the Session Controller or the key is pressed on the KC-24 the
RADAR will locate to the current incoming timecode position, lock and then begin to play. Prior to using
the chase function, make sure the proper TC SETTINGS have been set in the SYNC menu.
CHASE MODE
CHASE MODE determines the chase behavior of RADAR. When set to RECHASE, RADAR will locate,
lock and begin playback, continually comparing its position with that of the incoming timecode. When set
to LOCK-AND-DROP, RADAR will locate, lock, begin playback and immediately switch back to internal
clock. When set to NUDGE, if the timecode drifts, the clock speed will temporarily adjust (override) to
bring the timecode back in sync.
Both the SYNC REFERENCE and POSITION reference will switch to INTERNAL (CHASE and SYNC
LEDs will switch off) if set to SMPTE or MTC. If the RADAR is required to stop manually and rechase to
the incoming timecode, the
key must be pressed (and key if also using SMPTE or MTC as a
SYNC REFERENCE) in order for RADAR to rechase again (SYNC and CHASE LEDs flashing). This lock
and release behavior is sometimes required for transfers from media with poor/damaged timecode or
during a live recording etc.
There are three options for handling the situation where the clock (sync) source and the timecode (chase)
are not in sync with each other:
LOCK-AND-DROP
Chase to the incoming timecode initially, but once positional chase is
established, stop looking at the timecode (turn CHASE off); therefore, rely
only on the clock source and ignore any timecode drift (this is the former
RECHASE DISABLED mode).
RECHASE
If the timecode drifts, cue RADAR
again and reestablish positional chase;
therefore, rely on both the clock source and the timecode source.
NUDGE
If the timecode drifts, this option will temporarily adjust (override) the clock
speed to bring the timecode back in sync; therefore, rely primarily on the
timecode source.
Timecode preferences can be accessed by pressing + (TC PREF). Changing these settings will
have a direct effect on chase operation. These preferences can also be accessed using the MAIN MENU
/ SYNC MENU / TC SETTINGS / TC FORMAT dialogue.
