PAVGeneral purpose preamplifier Description and Features PAV preamplifier has the function of AST, and could effectively shielding electromagnetic interference and resisting impact with metal shell. It is phantom power supply, and it is compatible with most common sensors and acoustic emission acquisition boards on the market. Technical Specs > The power supply should be a good match with the output impedance, otherwise it will lead to the gain of the preamplifier to deviate from the nominal gain value, resulting in signal amplitude deviation. > If acoustic emission acquisition board from other manufacturers are selected, a PPS preamplifier power supply is required. > Wiring must be correct.The following two wrong operations may lead to damage to the preamplifier: The input voltage is 25% higher than the power supply requirement Connect the power supply to the sig nal input connector.
