actiCHamp Plus

The new versatile all-in-one lab amplifier

We are excited to announce the new actiCHamp Plus, offering a scalable and flexible solution for your laboratory EEG recordings. The actiCHamp Plus can be combined with all our active as well as passive electrode systems – incl. the R-Net, and is powered by a sturdy lithium-ion battery, the PowerUnit.

actiCHamp Plus at a glance

  • Compatible with all our active and passive electrodes
  • Scalable for high-density recordings
  • Easy synchronization for multiple recording modalities
  • Powerful lithium-ion battery pack
  • Integration with EEGLAB, MATLAB®, LSL, OpenViBE

All electrode options to best fit your needs

  • Record with easy to prepare active electrodes* (actiCAP slim) 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 in 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
