A DC-coupled, digital amplifier system with a high input range and 24-bit resolution providing amplification and digitization of electroencephalographic physiologic signals from surface, cortical and depth electrodes. The amplifier provides 40 channels (32 isolated high-frequency referential channels, 8 bipolar channels) and an integrated pulse-oximeter and event button input. The unit has a POE 10OBASE-TX network connection for both power and communication.
