E allows to set the unit by USB, ignoring switch settings. A turns off the video signal / audio generator if used as time code genearator only to save battery life. Exception: TC-lockout / userbit insert with dip switch 1 Yellow Switch: Main On/Off Rotary encoder switches with 16 positions behind the battery lid: Switch 1: Type of sync signal: This switch determines what type of signal is present on the BNC connector next to the edge of the unit. 1ฤก.1 Controls All changes of the settings take effect only after reboot of the unit. Please refer to 1.4 for battery lifetime and low battery reference. Extensive unit monitoring through 2 LEDs.24, 23.98, 25, 29.97, 30 Frame Timecode locked to PAL, NTSC and HD formats (SMPTE 296M and SMPTE 274M), Wordclock or AES-3 black audio in all standard sample rates with pull-up and pull-down.Crystal oscillator for video and trilevelsync locked to reference oscillator low jitter high stability signals.Can be calibrated in the field to 0.2ppm using Clockit Controller ACC101 or ACC501. Hightly accurate DTCXO reference oscillator.Clockit tunable reference oscillator for timecode generation gives typically less then one half frame a day timecode drift.The Lockit can be jam synced with external timecode, set using the Ambient Controller ACC501 via ASCII through cable or Infra Red, or set by Aaton "OrigenC" ASCII code. Each machine is jamsynced and Genlocked, (if possible,) to its own Lockit which is synced to a common source before the machines start. The Lockit can be used in any recording situation where the accuracy of the TC generators in the different machines is not known and where a cable connection is not possible. Typically, the drift will be less than one half frame a day, giving problem free editing and syncing in post production. Audio and video machines such as DAT, harddisc and DVD recorders and HD and Digibeta cameras can be synchronised to the Lockit box, thus giving very low drift between machines, allowing multicamera shoots to be carried out without cables or timecode radio links. The Lockit synchroniser ACL 203 Description The Ambient Lockit ACL 203 is a highly accurate portable timecode and video sync generator.
