  10. The function keys can be set to any of the options you require but you are advised to set F1 to Live and F2 to Cue –4 . Cue –4 plays back the disk 4 seconds behind the recording and is a very good check that the disk is working correctly.
  11. Next go to item 35 and set the jog EE OFF to ON. This will make the jog knob LIVE and moving the jog knob will cue up the disk to the current record time less 3 seconds (buffer in the SX machine)

  15. If loop record is successful the machine will go into LIVE Mode (F1 auto selected)
  16. Now press F2 the disk should play back 4 seconds behind the recording.

If it is still not working properly it might be necessary to delete all files from the hybrid. This is done from the machine.
  17. With loop record working, press Enter to enter timecode cues
  18. Press search to search to the last cue entered. Remember that there is a 3 second buffer in the hybrid which will prevent you cueing up LIVE action before 3 seconds. The AVM-4 will wait the required period to prevent accidental cueing in this 3 second window. If the cue is more than 3 seconds away from the LIVE recording the disk will cue up instantly. Moving the Jog knob will instantly force the disk to cue up at the buffer point (3 seconds after recording)
  19. To view previous cues, press CUE VIEW (browse), move jog knob to the desired cue and press search to search to that cue.

27. To force the disk to cue up while in CUE VIEW, hold down the shift button while moving the jog knob. This allows the operator to view the first video frame of every cue in memory. There are 1000 memory cue points.

28. If you know what cue you wish to go to, enter the cue number directly into the keypad followed by SEARCH.

29 If you wish to make a tape recording while in loop record select item 34 slave SX to on.

30 To enter a quick cue, hold down the shift button and press the nominated function key (F5 or F6 in our example) at the cue point. To cue up just press the function key. Note: F5 and F6 are cues 15 and 16 in memory. If all function keys were set to quick cue they would reside in memory locations 11 to 18. It is therefore possible to view the quick cue timecodes by using CUE VIEW.

31 To search to a timecode on the disk press SET IN followed by the timecode number to store this number press ENTER. To only search without storing the number in memory just press SEARCH.

32. F4 was set to user delay this mode allows the operator to set item 33 in the menu to the playback delay he requires.


33. If you wish to operate the disk or tape from the Avm-4 it must first be selected from the front panel before putting the hybrid into remote. Coming out of remote while in loop record will cancel the loop recording. This is to prevent the disk from crashing.
