Ambient ACN-CL Lockit
"The Lockit" Timecode Synchronizer for cameras and audio recorders, Timecode and Genlock, ACN compatible
Since its first appearance in 1993 the ACL "Lockit" has become synonymous for reliable on-set synchronization.
Over time it was updated with a host of features we now take for granted from HD sync to metadata. Two AAs soon replaced the 9V battery, flying leads changed to fixed sockets, the BNC timecode output was sacrificed in favor of a second Lemo sporting TC I/O and a serial metadata port, a display-guided menu thrown in and, of course, we introduced the ACN, a powerful wireless timecode and metadata network.
Despite all these changes and a massive increase of processing power, we were able to maintain its iconic form over all those years. But now it's time for our old buddy to step aside for the next generation.
Just like the NanoLockit, jamming units to time of day with the internal Real Time Clock is a one button experience, but with the additional perk of a crisp OLED display. Lockit can also operate as master by automatically jamming units that are added or restarted during the day.
The OLED also brings the useful timecode compare tool introduced with firmware 6.0 so it is easy to determine if other equipment is still in sync - with an accuracy of 1/100 of a frame.
Size and Signals
While our smaller units were always marked by a prefix such as Tiny or Nano, the ACN-CL proudly carries the name "Lockit" and it wouldn't do so without supplying both timecode and sync signals.
Designed for today's equipment it supports 1080P and 1080i genlock for project rates 23.976 to 60 FPS while audio recorders are covered with wordclock up to 192 KHz.
Dual Lemo output connections provides maximum flexibility and continued use of available cables. TC in and out follow industry standard and allow for syncing of 2 cameras in parallel or jamming via a cable while leaving the synced unit connected.
The primary output carries timecode and genlock/wordclock. This gives you the freedom to choose running it either on straight, Y-split cable or 2 separate leads using the second connector for timecode which also connects to devices that support ACN for metadata transfer.
Powering and charging
External power and charging are available through a common USB-C port. Connected to a Mac or PC the Lockit transforms into a MIDI timecode interface without additional configuration and allows for deep level editing of the settings.
Not just for the bling the sync LED is now full RGB so we have another color for status indication and party mode. We fit all of this and more in a compact solid aluminum case that makes the ACN-TL TinyLockit and even ALL601 LancLogger look large by comparison.

Great build quality, super performance!
Lots of TC solutions on the market now but none have the built quality like Ambient and the functionality is superb. Def buy again.

Small learning curve but a great unit.
I bought one of these to see if they can eventually replace all my ACN-TL tiny lockits. Half the size and weight. Battery life 16 hours, NP-50 battery charges in about 2 hours in the lockit. Less menu options but more will come with coming updates. No offset yet but am told it will be coming soon. Read more
Most other functions are there. You will be setting some of them in the toolbox via a computer connected to the web. Photos shown are of the prototype not the unit that ships. Check the Ambient site for updated images. Overall, after figuring out how to navigate the menu I like it. Solid unit and I can see myself replacing the rest of my units with these. Cables are included, one LTC-out, one Sync, One USB-C to USB-A. Kit comes ready to roll.
