Introduction
The Ambient ACL 204 Lockit box continues the line of our highly accurate portable
synchronizers, which have become an indispensable tool in modern workflows where multi
camera shoots and dual system sound is the rule.
Like its predecessors, it provides time code with a deviation of less than +/- 0.1 ppm of a
given reference and a sync signal locked to this. The Clockit time code products can be
calibrated to this reference in the field using the Clockit Controller ACC501, providing the
same accuracy still after years, compensating the usual aging of the crystals, and opening
possibilities which are unique to the Clockit approach.
What counts on a set is that all recording devices run on the same speed, and with the
Clockit method of being able to tune the devices, this goal can be achieved.
The reference for tuning may be a GPS signal, but just as well the time code of the master
recorder or camera or a video reference signal generated by the studio / OB-truck’s
synchronizer.
In addition to those classical features of the Clockit product range, the ACL 204 features a
wireless network module and a serial data port, so the status of each unit on set can be
monitored and metadata of the connected devices can be communicated to the Ambient
Clockit Network ACN Master. ACN also permits to sync the ACL 204 remotely and write back
metadata to the recorders.
