ER-1 Differential Extracellular Amplifier
The ER-1 is a compact, inexpensive, and versatile amplifier which is primarily intended for extracellular use. The ER-1 offers a number of both high and low pass filtering settings and a range of gains. The remote headstage has high imedance differential inputs and includes a bypass relay to connect the electrode to an auxiliary instrument such as a stimulator.
