I was wondering if the Olimex active electrodes could be used with other EEG amplifiers, and if so, would I need to use a certain number of active electrodes but also include a passive one, for the ground signal? I may have an opportunity to purchase a used Stellate EEG system and am unsure whether your active electrodes may be used with other systems like Stellate or Nicolet. I am debating whether to purchase the used hospital EEG system or a couple of Olimex EEG SMTs. I am very new to this and greatly appreciate any feedback you can provide.
The active electrodes work at 5V and follow the layout here: https://www.olimex.com/Products/EEG/Electrodes/EEG-AE/resources/EEG-AE.pdf (https://www.olimex.com/Products/EEG/Electrodes/EEG-AE/resources/EEG-AE.pdf). Generally our EEG-SMT devices are more of a hobbyist electronics tool (despite packing good accuracy) than professional hospital equipment. The devices you mentioned tend to be in the second category.

Hi, sorry for the trivial question.
It is possible to use AE at 3.3V ?

It is not recommended. There are ways to make them work - among those: driving the 5V from the EEG-SMT to 3.3; providing external supply for the AEs. Still I think this is not a justified effort.
