The Net Amps 400 amplifiers use EGI's ADAPT technology, which builds on-board computing directly into the amplifier and includes state-of-the-art hardware and firmware. ADAPT includes:

  • a built-in Intel processor supports computing capabilities; such as remote software and firmware updates
  • upgraded, more robust electronics for faster processing
  • fiber optic signal input and output for optimal digital bandwidth and an extra level of safety isolation
  • built-in clock sync port for MR and MEG applications, and for synchronous acquisition by multiple amplifiers 
  • support for 32 extra channels of physiological measurements using EGI's Physio 16 input box

The Net Amps 400 series amplifiers are specifically designed for EEG acquisition using EGI's HydroCel Geodesic Sensor Net with 32, 64, 128, or 256 EEG channels, with additional capabilities for input from up to 32 bipolar channels. Three amplifier configurations allow you to choose the best one for your needs.
