PA-2S User Manual ___________________________________________________________________________ 2.3. System Grounding The 19" cabinet is grounded by the power cable through the ground pin of the mains connector (= protective earth). In order to avoid ground loops the internal ground is isolated from the protective earth. The internal ground is used on the BNC connectors or GROUND plugs of the modules that are inserted into the EPMS-07 housing. -

3.2. System Description The PA-2S amplifier is a plug-in unit for the npi EPMS-07 modular system. It is designed to amplify small bio-electrical signals. Two channels are available and can be used independently from each other in AC or DC mode. DC offsets can be compensated either by the using the OFFSET controls (coarse and fine) or they can be eliminated using the AC position of the input switches. -
