» The professional Ambient underwater sound « With the ASF-2 MKII we use parts of the ASF-1 technology to create an affordable, great sounding hydrophone. It comes with a 10m moulded cable to make it easy to use - no extra equipment required.
This is a natural process which won’t damage the unit nor affect the usability. If the corrosion is starting to dissolve the metal, stop using the ASF-2 MKII immediately and check if the housing is connected to any ground. (More info in “4. Powering”) Never use the hydrophone within acids or bases.
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-2 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.
