Phoenix A202 2-channel EEG Amplifier

Famous for its signal accuracy and rugged design, this amplifier was designed by Phoenix Neurosystems, a company with 30 years of experience manufacturing neurofeedback devices. Now manufactured by Southeast Signal, this robust and sensitive amplifier is USB-powered, so it does not require batteries like many other amplifiers. Signal response of this amplifier is superior to that of all other EEG amps tested by the technical staff at EEG Store.
