페이지 인쇄The output of your H2b is configured dual mono—both the left and right stereo channels are from
the same source. This configuration is quite versatile because the hydrophone will drive both channels of
a stereo device and will work with all standard computer sound cards. Inserting a TS, or mono, plug into
the output jack of the H2B will short the output. This will not damage the H2b but will prevent operation.
The H2b uses a 3.5mm female TRS jack for electrical connection. This jack is also referred to as 1/8"
stereo, mini, or phone jack. This is a very common audio connection. Mating plugs and molded patch
cables are widely available. This connection also allows the plug to rotate within the jack while threading
the H2b into its mount if a blind connection is necessary. The tip and ring connections are wired "hot"
while the sleeve serves as signal ground and is electrically connected to the stainless steel body of the
hydrophone.
If this connection will be exposed to a damp or corrosive environment, you can extend the life and
reliability of the electrical contacts by applying a silicone grease to the mating plug before insertion and/or
an RTV sealant between the housings of the plug and hydrophone. Using high-quality and well-shielded
connectors and patch cables will help control unwanted noise.
Specifications
The H2b is intended to be durable and low-cost. Deriving high sensitivity and low noise from lower-cost
components were made a priority over maintaining strict tolerances. The following specifications are
typical of a limited sample group and are not guaranteed. They are for basic comparison information only.
Specifications are dependent upon the audio device to which the H2b is connected. The hydrophone
sensor is capable of picking up sounds from below 20Hz to over 100KHz. The output impedance of the
H2b is set in part by the bias current supplied by your audio device. High-frequency performance is also
limited by the output impedance of the hydrophone and the cable impedance—which is a function of
length. Please also note that further limitations in your overall system may result from the sampling rate of
digital recorders and by the input stage of your audio device's microphone preamp. Despite the
uncertainties of above, you should expect to easily capture the entire human auditory range of 20Hz to
20KHz.
