Neural Signal Amplifier Input
The Amplifier has four 34-pin banks. Each bank consists of 32 channels, a bank reference pin, and a ground pin.
The electrodes within each bank are differentially amplified with respect to the reference input of the same bank. If
channels on all banks are to be electrically measured with respect to a common reference, this reference needs to be
connected to the reference input on every bank.

Additionally, four 6-pin APS banks provide power (±5V) to the headstage and are capable of delivering 130 mA of
combined current from the Amplifier. The ground pins on every bank are tied together. For best results, the
Amplifier should be the central grounding point for electrical ground connections to the research subject.
