Page 4: General Information
We will coordinate communication with your dealer in case you purchased the device locally. INTENDED USE The eego amplifier is intended to be used by or under the direction of a physician for acquisition of EEG signals and to transmit them digitally to a computer. -
Page 5: Safety Warnings
The following warnings and cautions apply to the eego amplifier: Proper use of the eego amplifier depends on careful reading of all instructions and labels that come with or on the device inaccurate measurements may be caused by incorrect use of the device. -
Page 6: Precautionary Measures
The eego amplifier should not be used adjacent to or stacked with other equipment; if this is still necessary, verify normal operation in the configuration in which it will be used. Do also not stack multiple eego amplifiers directly on top of each other. -
Page 7: Maintenance And Cleaning
USB devices, and do not make changes to any connections. If the eego amplifier is upgraded or replaced for any reason, make sure to have the control software and interfacing computer checked for compliance by eemagine support before continuing to work with the device. -

Page 9: The Eego Amplifier, Hardware Setup Description
Figure 2-1. The eego amplifier EE-211 amplifier shown from the front. The amplifier (white) is mechanically protected by the eego amplifier soft-shell (blue). Two high density connectors (EEG IN 1 and EEG IN 2) provide access to 64 shielded referential inputs, reference and ground. The openings allow securing the amplifier, e.g., on the table. - Page 10 The trigger adapter XS-230 allows to connect eego amplifier with DSUB25 compatible trigger sources. Figure 2-3. The eego amplifier shown from the rear. The ON/OFF pushbutton to the left is the power button. The TRIGGER high density connector gives access to 8 electrically decoupled TTL lines for recording of synchronized trigger input.

Page 13: Biosignal And Impedance Measurements
Measurements of physiological parameters such as EEG require highest quality and fidelity of the electronic equipment and sensors used with it. The eego amplifier has been developed on the basis of latest state of the art core electronic components (integrated circuits). The modern chip-set allowed miniaturizing hardware without compromises in signal quality and keeping the power consumption at a minimum. -
Page 14: Recording Trigger Input
(less than) ms (milliseconds) and a few nV (nano Volts), depending on the selected sampling rate, signal range and resolution (see eego amplifier datasheet). Each signal is treated by its own converter, so that no multiplexing effects occur. -
Page 15: Battery And Charger For The Eego Amplifier
WARNING: Do not attempt to open the amplifier or battery compartment yourself! The battery charger for eego amplifier comes with a power cord and plug fit for a particular region. A green LED indicator in the power supply shows whether the device is turned on. -
Page 16: Led And Sound Status Indicators For The Eego Amplifier
LED AND SOUND STATUS INDICATORS FOR THE EEGO AMPLIFIER The LED light-pipes at the side edges of the eego amplifier communicate POWER and DATA status as well as possible hardware problems. The two multi-color LED indicators at each side operate symmetrically. -
Page 17: Appendix A: Connectors And Pinning Tables
APPENDIX A: CONNECTORS AND PINNING TABLES EEG CONNECTORS (REFERENTIAL) The eego amplifier has two EEG input connectors, EEG IN 1 and EEG IN 2. The 68-pin high-density, high-quality connectors give access to the 64 shielded referential inputs, the reference electrode and the patient ground, and are typically used according to the pinning tables below. -
Page 18: Bipolar Connector
EE-21x EE-22x User Manual BIPOLAR CONNECTOR The eego amplifier has one bipolar input connectors, BIPOLAR IN. The 50-pin high-density, high- quality connectors give access to the 24 bipolar inputs and the patient ground. The patient ground is identical to the referential channel patient ground. Only one patient ground connection should be established and used when preparing a subject. -
Page 19: Trigger Connector
EE-21x EE-22x User Manual TRIGGER CONNECTOR The eego amplifier provides an 8-bit trigger input via the 36-pin high-density connector at the amplifier backside. The trigger connector is compatible with the XS-230 trigger adapter, which should be used whenever connecting the amplifier with a trigger source (TTL). -
Page 20: Power And Usb Connector
Do not connect any other power source to the amplifier! The USB connector of the eego amplifier is typically connected with the USB port of a computer (USB plug type A). This cable is necessary for data transmission. It does not power the amplifier or battery but supplies the electrically isolated USB communication module. -
Page 21: Appendix B: Amplifier Technical Specifications (Emc)
32 unipolar EEG inputs) Guidance and manufacturer’s declaration – electromagnetic emissions The eego amplifier is intended for use in the electromagnetic environment specified below. The customer and/or user of the eego amplifier should ensure that it is used in such an environment. - Page 22 RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the eego amplifier is used exceeds the applicable RF compliance level above, the eego amplifier should be observed to verify normal operation.
