All Hydrophones are Active meaning that the amplifying electronics are inside the hydrophone casing. There are two MODES:

1. Long Distance HIGH GAIN with Automatic Gain Control and

2. Short Distance LOW GAIN with NO Automatic Gain Control.

The first mode is used to listen to creatures at a distance with no powered boats operating in the area. The second is used when other powered boats are close by. A contact at the surface end of the cable sets the MODE.

Sound is provided at "Line Levels" not "Microphone Levels". In addition to the plugs connecting to your ship board stereo amplifier system, a red wire connects to the stereo 12 Volt positive source. This supplies a low current bias to the hydrophone active electronics.
