The H2a hydrophone is designed to work with any recording device, computer, or transmitter that offers a plug-in-powered, 3.5mm microphone input. It uses the same low-noise, robust transducer assembly as our other hydrophones, but includes a low noise internal impedance buffer amp. Operation is very simple: just plug in and use. No additional power supply or proprietary preamp is required. The H2a offers the following advantages:

  • Low cost
  • Low self noise
  • Good sensitivity
  • Robust design handles accidental drops and temperature extremes
  • Compact (4.5mm OD) Low-noise cable with tough urethane jacket
  • Connects directly with thousands of consumer audio, wireless and computer products.
  • Adapters allow use with telephone, radio, and pro audio equipment.
  • High-quality Neutrik gold output connector
  • Compact size and easy hand of cable
  • High specific gravity and streamlined shape keeps hydrophone down in currents
  • 1-year limited warranty

COMPATIBILITY NOTES: The output connector used with H2a is also used for many other types of audio connections. A compatible jack does not ensure proper operation.

MARINE STEREOS: The H2a hydrophone will not work with a line or auxiliary audio input on a marine stereo system. It will connect to many stereos, but these will not supply plug-in power or adequate gain. A mic preamp is required.
DIGITAL RECORDERS: Many of the new digital recorders require that you go into the menu system and switch on plug-in power. The H2a will not work before doing this.
