ACN-ML – The Lockit flagship and hub of the sophisticated ACN System
Downloads | Purchased Parts Package | Accessories | Timecode Cables | Timecode Tutorials
The ACN-ML Master Lockit is both the flagship and hub of the sophisticated Ambient ACN system.
It 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
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.
Metadata Network
Lockit Metadata Communication
As productions already use Lockits and connect them to cameras, 3D-rigs, Sound recorders…, ACN-equipped Lockit units can also read out device-specific metadata for transmission to the Master Lockit server. While the internal memory centrally stores and hosts all metadata collected through ACN connected units, iPads running LockitSCRIPT automatically sync their data though the Master Lockit’s router functionality.
Based on the unrivaled accuracy of the Lockit system, the ACN uses global timecode as reference to create a comprehensive shot list containing crucial clip information like name, roll number, start and stop times of each and every recording and machine.
Ambient has developed Lockit OEM modules with full ACN capabilities available for effortless 3rd party integration. This provides other equipment manufacturers the ability to incorporate Ambient’s highly accurate timecode and metadata network.
The ACN utilizes an extremely reliable, proprietary 2.4GHz ̶ network with 16 selectable channels for communication to minimize lag and interference with other radio sources. All gathered information is buffered until it is successfully received and stored.

Remote Features
With Firmware 4.1, we integrate remote functionality for the renowned Sound Devices 633, 664, 688, and 788T into the Master Lockit’s capabilities. The new Remote Control Tab in the Master Lockit’s web interface provides wireless access to the most important recorder functions like Record Start / Stop, Track Naming, Track Arming, Metadata entry for the current and upcoming clip, Circle & Waste Clip, Track Metering (with the 788T), Access to the metadata of the last clips.
Audio Professionals can also combine the added control of Master Lockit along with CL-12/ Alaia Linear Fader Controllers as they perform seamlessly together for even more powerful control of 6-Series Recorders.
Cross-Platform Elegance
The Master Lockit control surface is self-contained and accessible from any device with a browser and WiFi – so it is not bound to a specific platform like iOS or Android. In other words, any device with integrated WiFi and browser can connect to the ACN-ML web interface without limitation.
Thanks to its responsive design, the control interface will always automatically adjust to your screen size. This not only enables use of a notebook on the sound cart, it allows seamlessly switching to a smartphone for run-and-gun situations.

DIT Features

With the LockitScript app, script supervisors note content information for every single clip. The Master Lockit Web Interface enables DITs to access the merged data through the Master Lockit in real-time, and to download important clip-based content information as e.g an ALE-File for direct import into your pregrading software.

How-To:
- Tell a script supervisor to work with the LockitScript app and a Master Lockit on set
- Connect to the Master Lockit WiFi with your laptop
- Enter the Master Lockit Web View in a browser
- Go to Tab “Metadata Export” and select the information and format you need
- Download the selected file directly to your accessing device
