Using the Hydrophone
To ensure optimal results, certain steps must be taken to prepare the
Hydrophone for use, bearing in mind any possible adverse effects of the
environment or medium in which it will be immersed. Please read the
important tips and precautions below.
Important: The 3-pin XLR connector is not waterproof. Do not immerge the
XLR connector in water and keep it dry at all times.
Important: The water medium often has a different electrical potential than
the ground potential of the electrical equipment. This phenomenon might
cause unwanted noises and hum in the Hydrophone. In order to prevent
these noises from occurring on the recording, the water medium must be
properly connected to the chassis ground of the electrical equipment in use.
A cobber wire immersed in the water and connected to the chassis ground
will solve the problem.
Important: Many small air bubbles covering the element can affect the
sensitivity of the sensing element. The element must be in full contact with
the medium in order to meet the specifications. A wetting agent such as liquid
soap can be applied to ensure that bubbles do not adhere to the surface of the
Hydrophone. Clean the Hydrophone carefully before and after use.
Important: The Hydrophone is supplied with a 10 meter (30ft) long special
quality cable as standard. It is not possible to extend existing cables.
Hydrophones with longer cables can be ordered on special request.
