actiCHamp Plus: Versatile all-in-one lab amplifier

actiCHamp Plus is a scalable and flexible amplifier solution for a wide range of laboratory EEG recording applications. It can be combined with all our active as well as passive electrode systems and is powered by a sturdy lithium-ion battery, the PowerUnit.

actiCHamp PlusAll electrode options to best fit your needs
    • Record with easy-to-prepare active electrodes (actiCAP slim/snap or actiCAP Xpress Twist) for best data quality
    • Easily switch to passive sponge-based electrodes (R-Net) when high channel counts and quick preparation times are crucial
    • Choose gel-based passive electrodes using our fully customizable BrainCaps*
Scalable solution
    • Modularity for recording 32 to 160 channels
    • 8 additional AUX channels for including extra physiological sensors
    • Up to 100 kHz sampling rate
Highly integrated for multimodal recordings
    • Clock synchronization outputs allow for easy integration with external devices (e.g. TMS, EMG)
    • Forward incoming triggers to other signal acquisition systems (e.g. fNIRS)
Powered by lithium-ion technology (the PowerUnit)
    • Long battery life with low self-discharge rate
    • Extended recording times due to higher battery capacity

* Adapter/control box may be required for this combination.
