Features

  • Versatile DC-Coupled amplifier with fast settling time, high dynamic range and high common mode rejection ratio for high-quality, continuous ICU monitoring
  • 33 DC-Coupled referential inputs
    • 24 inputs for scalp electrodes (including reference)
    • 9 inputs for additional channels or emerging applications (including reference)
  • Four dedicated true-differential inputs for EEG or other physiological signals (e.g. ECG, EOG, EMG, Respiration, etc.)
  • Up to 2,048 Hz sample rate for each input*
  • Continuous independent impedance checking to verify electrode connection integrity (can be disabled by user)
  • Selectable sampling rates for recording high frequency EEG on all channels synchronously*

Amplifier Inputs

  • 24 dedicated, DC-Coupled referential EEG electrode inputs
  • 9 dedicated, DC-Coupled inputs for additional EEG signals or emerging applications (with dedicated reference input)
