Yes, all of our current models support High Speed Synchro (FP flash / HSS).
Please refer to the manual of the model you are using as the setting and switching method varies depending on the model.

When using High Speed Synchro with AirR in a NAS system, the flash attached to the AirR must also be compatible with High Speed Synchro.
If a non-compatible flash is attached, the flash will not fire properly.
