DIGIGRID DLS/DLI
3.5 Clocking in I/O Mode
A Pro Tools HD/HDX or HD Native system has its own playback engine and its own clocking environment. A SoundGrid network has
its own driver and its own clocking environment. There are therefore two complete clock systems at work:
• DigiLink-compatible I/O devices connected to a DLI/DLS
• A SoundGrid network that includes the DLI/DLS
Regardless of system size, the rules of managing clock remain the same. Details change according to the specic hardware devices
and the type of Pro Tools used.
3.5.1 Clocking Example #1: DLI/DLS is SoE Master; 192 is Loop Sync Master
This conguration adds eciency to Pro Tools HDX mixing environments. In this conguration, a SoundGrid network delivers
exibility to a control room equipped with a Pro Tools HDX system. DiGiGrid DLS interfaces provide 48 I/O channels to the HDX
system and a SoundGrid DSP server for plugin processing. A DigiLink, compatible I/O is used for hardware connections.
All these devices are joined via DigiLink and clocked with Sync Lock. Everything else in the network is connected with Ethernet
cables. A DiGiGrid MGB/MGO interface connects this network to a MADI source or destination, for instance a console or a MADI
distribution system. DLS is SoundGrid network clock master. The MGB MADI interface clock is slaved to the SoundGrid Network.
