The Ambient Master Lockit is a timecode master and ”On the Set“ metadata server.

With its dual processor architecture, the Master Lockit truly is the most powerful timecode device we have ever built. Using the acclaimed Lockit timecode generator with its rock-solid, high-accuracy, temperature-compensated oscillator, along with the sophisticated ACN, the Master Lockit offers features like generator-buffered timecode transceiving or 0.0ppm drift between linked units through the unique continuous jam with control and monitoring through the integrated web GUI.

The new control center for all Lockits in your arsenal

The Master Lockit adds control, flexibility and comfort to your existing Lockit setup. Being designed to perform as central hub in your system, the unit is able to display and control all other ACN devices on set.

Access the ACN control system using the browser of any computer or mobile device via Wi-Fi for elegant wireless functionality. This enables you to name your Lockits and assign them to the camera or audio recorder to which they are connected.

What’s more, you can remotely jam sync all units on set, view battery status, set the time, use time of day, see the last clap time of the ACN-LS. Thus, one ACN-ML on your sound cart or in your bag improves efficiency by enabling control and monitor capability from a single location. Simply switch on your Lockits in the morning, set them to the correct ACN channel, and mount them on the device. The rest can be performed remotely and you always are up to date what your units are doing.

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 reduces paperwork, duplicate listing and overtime after wrap.

Both the ACN timecode devices and the LockitNetwork apps are excellent stand-alone tools. When used together, these technologies provide accuracy and elegance unsurpassed by any other workflow.

That’s why we decided to include a free-of-charge LockitScript app license with upon registration all ACN Lockit devices (blue).
