Product Name:

 

eego

 amplifier 

Product Code:

  EE-211, EE-212, EE-213, EE-214, EE-215 / version 1.2  

EE-221, EE-222, EE-223, EE-224, EE-225 / version 1.2 

Classification: 

CE class IIa according to the MDD 93/42/EEC Annex IX 

Description:

  

The 

eego

 amplifier has been designed as a mobile recording device for high-density 

EEG and other electrophysiological signals. It provides access to recorded data over a 
USB connection to external software over its signal driver interface. The 

eego

 

amplifier comes with a built-in rechargeable battery for recordings of several hours. 

The device provides maximum 64 channels of referential EEG and (optionally) 
synchronously recorded 24 bipolar input signals.  

The 

eego

 amplifier is used in combination with the 

eego

 recording software. 

An SDK is available for direct amplifier communication. 

The implemented active shielding technology protects the EEG inputs from grid 
interference noise. 

Sampling rate and gain can be set through the user interface of the control software.
