The Active3 and the Active2.5 use the new MK3 connector. The Active2 uses the old MK2 connector.
You can read more about the compatibility of the electrode sets here: All questions about the Active3 system.
For the new Active3 model, it is no longer possible to have the CMSDRL integrated in the A-set, so the separate CMSDRL cord will always have to be used.
Because the new Active3 model (and Active2.5 model) use a different connector, it is important to always order the correct electrode sets for your AD-box.
All the differences between Active2 and Active2.5: - No integrated CMSDRL possible anymore on the Active2.5
- New Mk3 connectors (not compatible with previous AD-boxes)
- AD-box has a new top with colors
