Like its bigger brother, the »Tiny Lockit« provides a rock solid, highly accurate, temperature compensated timecode generator.

For about 20 years, the Ambient Lockit is the market leading portable, timecode and sync generator worldwide. Like all Lockit devices, the ACN-TL is based around a highly accurate, tunable, temperature compensated crystal for reliable synchronization of multiple devices without cables or fragile wireless transmission. The new ACN network-generation adds even more accuracy and comfort to the system, while maintaining the renowned reliability. Except for the sync signal output, the Tiny Lockit comprises the full functionality of the Lockit, including ACN support, auto tuning, wireless jam syncing, as well as metadata transfer and logging.

Built-In timecode wireless & C-Jam

The ACN-TL also can be used as fully-functional, generator-buffered timecode transceiver. This provides the stability of an Ambient Lockit generator with the flexibility of a wireless TC system but without the fear of dropouts. In addition, it also offers a variable timecode output level for recording TC on audio track.
Due to its smaller form factor, the ACN-TL is especially suitable for applications on small cameras and in setups where a sync signal is not required. With it’s machined, pearl blasted and anodized aluminum body, the Tiny Lockit can easily withstand the roughest production conditions.

RED Digital Camera Features

ACL204RedWe proudly announce that RED Digital Cinema has joined the Ambient ACN family.
With firmware 4.1, all ACN-TL Tiny Lockits, ACL 204 Lockits and ACN-ML Master Lockits are able to read out and distribute metadata from RED Scarlet, Epic, and Weapon cameras that is then stored on a Master Lockit.
The stored metadata can then merge with data generated by the Script Supervisor using the LockitScript app, and exported to post, or accessed via the Master Lockit’s WiFi for DIT use.

Our RED protocol integration includes nifty feature which greatly simplifies the setup RED cameras and Lockits. When connecting the ACN-TL to the CTRL port of the camera, the Tiny Lockit will automatically sense camera type, and timecode frame rate – and match those settings. Then just connect the timecode cable, and the RED camera is plug and play.

The built-in ACN enables for 0.0ppm drift, wireless tc & remote control
The integrated transceiver and the 2nd Lemo socket can be used to interface with the ACN system via USB, RS232, or GP I/O. It also allows the ACN-TL to work as a fully functional, generator buffered wireless timecode 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. When used in a network with a Master Lockit, all ACN-TL units and other ACN Lockits can be displayed, named and remote controlled via the Master Lockit web interface.
Use your Tiny Lockit as computer Timecode Interface
Plugged in into a computer, the Tiny Lockit transforms into a highly accurate Midi Timecode Interface with LTC / Midi Timecode conversion. This enables ACN-TL to sync multiple cameras with a Pro Tools workstation.This is made possible by the ACN-TLs 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.
Free-of-charge LockitScript App
The LockitScript app elegantly accommodates all the daily needs within the demanding role of a Script Supervisor. This comprehensive and time-saving tool helps fighting paperwork, duplicate listing and overtime after wrap. 
Both the ACN time code devices and the LockitNetwork apps are excellent stand-alone tools. Once used together, you can experience the beauty of two worlds working smoothly together.
That’s why we decided to include a free-of-charge LockitScript app license with upon registration all ACN Lockit devices (blue).
