    Electrolysis is a tough problem while working with electrical equipment in a wet environment. To avoid any kind of electrolysis, the metal parts of the ASF-1 MKII are not and should not be connected to the audio ground of the unit. If the ground of the mixer / recorder is connected to the ground of the boat and the audio ground of the hydrophone would be connected to the hydrophone metal housing, the ASF-1 MKII would become the cathodic protection of the ship.
