4. Powering / Electrolysis

The ASF-2 MKII can be powered by 48V phantom power supplied by professional audio mixers &

recorders.

Electrolysis

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. This would cause immediate irrevocable

damage to the unit.
