The EA136 Pre-Amplifier System can be used with our isolation and data acquisition units or as a stand-alone upgrade to boost the performance of older systems.

Amplifiers have PTP noise of 0.89 uV (1-100Hz) 3uV/C drift for outstanding DC and noise performance. Input impedance is 1GW; offset potential tolerance is +/-40mV (requires Ag/AgCl sintered electrodes). Factory configuration is 64 monopolar, 4 bipolar channels for a total of 68; second board also provides 68 channel for a total of 136.

Our modular connectors make it easy to disconnect for a break, or to modify the array for use with a different amplifier - even during the same session.
