Ambient ACL 204 Lockit Sync Box Timecode and Sync Generator - Used

  • Used. 8/10 Condition. 
  • Unit has been repaired and refurbished.
  • Units have the latest Firmware and have been Factory Reset

For about 20 years the Ambient Lockit is the market leading portable, time code and sync generator worldwide. Like all Clockit devices the ACL204 is based around a highly accurate, tunable, temperature compensated crystal. This way it is used to synchronize different devices without any cables or fragile wireless transmission.


  • Highly accurate timecode generator
  • Generator buffered timecode transceiver
  • Drift of less than 1 frame a day (~0,1ppm, 0ppm within the ACN)
  • Supports all SMPTE frame rates
  • Supports all standard video sync and word clock formats
  • Sunlight readable OLED Display
  • Adjustable timecode offset
  • Dual Sync Mode, 2 TC Out for 3D use
  • Midi timecode interface with LTC/MTC conversion
  • Built in ACN transceiver with internal antenna
  • RS232, USB port
  • Works 30 hours on 2 AA batteries
  • Robust machined and anodized aluminum body
  • Dimensions: 100 mm x 74 mm x 36 mm
  • Weight (without batteries): 250 g

All Sync & Timecode Rates

Surpassing the already comprehensive facilities of its predecessor it not only covers all timecode rates and sync formats but it also allows the user to apply an offset to the TC output to allow for the processing delay created in some HD cameras.

3D Rig functionality

3D camera rigs can be made lighter and neater by utilising the 2nd TC output, and the sync OP which can be switched to drive a dual load.

The Ambient Clockit Network

The integrated transceiver and the 2nd Lemo socket can be used to interface with the Clockit Network System. It also allows the ACL 204 to work as a fully functional, generator buffered wireless Time Code transceiver. With firmware version 3.1 or higher the new c-jam mode does not stop after the first jam. It will resend smaller timestamps every 4 seconds.
All receiving units now compare their internal generated timecode with the highly accurate timestamp and pull up or down the generator speed until they are perfectly matched.This way a drift between all ACN devices on set can be avoided completely.

Use your Lockit as computer  Time Code & Sync Interface

Plugged in into a computer, the Lockit transforms into a highly accurate Midi Timecode Interface with LTC / Midi Timecode conversion. This way the ACL 204 opens up the possibility to sync for examples multiple cameras with a Pro Tools workstation.

To accommodate for all this the hardware has been completely revised into a flexible, fully programmable FPGA architecture. A front loaded OLED display will give instant visual feedback about the current configuration and assist while moving through the menu to make adjustments.

This is now done on the fly with an easy to operate one-finger navigation system - no more need for screwdrivers or powercycling the unit.

No mismatching Time Code & Sync settings anymore

An intelligent algorithm will prevent configuration of improper, mismatched TC and Sync rates or unintended alterations to the setup.

Still being a simplistic TC and Sync box at the core driven by 2 AA cells in the familiar rugged footprint the ACL204 can be considered the pinnacle of portable synchronization.
