HAPI MKII User Manual
In Pro Tools, the Clock source should be set to Internal for the device emulated by the IOM-H-PT64
module (HD MADI in the following example).
Sampling Rate mismatch protection
Audio from Pro Tools to Horus and from Horus to Pro Tools is muted when the Sampling Rate asked by
PT is not met by Horus to avoid recording when Sampling Rates mismatch.
Enable the Auto-follow SR option and Synchronize on PT module to avoid any SR mismatch.
Setups with multiple devices
If your setup is made of several Pro Tools Hardware interfaces that need to be synchronized, our
recommendation is to select Internal Clock Source of your IOM-H-PT64 module as the Master Clock.
The other devices present in the setup can be synchronized several different ways.
If two Hapi interfaces are used in a setup, they can be synchronized through the Word Clock
connectors. To send the actual Sample Rate, the Follow SR option in Setup -> Format must be
enabled.
