Cable*
NC-1-07 Active hydrophone
(integrated
preamplifier)
• Vessel with normal
level of noise (below
-100 dBV).
• Limited number of
sensors.†
• No filtering options.
• Not used for
positioning system
41-44 KHz 4-6 mA Green
NC-1-06 Active wideband
hydrophone
(integrated
preamplifier)
• Vessel with normal
level of noise (below
-100 dBV).
• Large number of
sensors.†
• Use at great depths (>
500 m).
• Gain configurable (Low
or High)
• Filters configurable (38
and/or 50kHz)
30-60 KHz 25-29 mA Yellow
NC-1-08 Active wideband
hydrophone
(integrated
preamplifier)
• Vessel with normal
level of noise (below
-100 dBV).
• Large number of
sensors.†
• Use at great depths (>
500 m).
• Gain configurable (Low
or High)
• Filters configurable (38
and/or 50kHz)
30-60 KHz 18-22 mA Yellow
*Note that cables are colored according to the type of hydrophone: blue for passive, green for
active narrowband and yellow for active wideband.
† Standard active hydrophones have an available bandwidth of 6kHz. So, if: (PRP_number * 100) +
(NBTE_number * 800) < 6000 you have enough place. If: (PRP_number * 100) + (NBTE_number *
800) > 6000 then you need a wideband hydrophone.
