Aquarian Audio Hydrophones
The Aquarian Audio is a high-performance hydrophone that offers exceptional versatility in a wide range of applications.
It currently is in its third generation of rugged and portable systems. The first units were originally conceived as recreational devices for sea kayakers wanting to explore with a device that was convenient to use and could withstand elements at sea.
The Aquarian hydrophone system has evolved to fit the needs of professionals while being even smaller, tougher and easier to use than its predecessors.
You CAN even use it as a contact microphone in free air: The Aquarian hydrophone system also works exceptionally well as a contact microphone by simply attaching the hydrophone (with a special adapter) to the media.
The Aquarian Hydrophone System is used in a diverse range of applications; each user's listening requirements are different.
No headphones, amplifier or patch cables are included.
Please do not overlook the importance of a good quality headset or amplifier/loudspeaker system to overall system performance.
It is easy to integrate into virtually any recording or amplifier system. The embedded preamp within the hydrophone will drive cable lengths up to 250 meters with negligible signal degredation, allowing you to use the system for remote listening.
• Gold-plated, user-replaceable output jack for corrosion resistance
• Can withstand a one-meter drop onto solid rock
• Power amplifier is short-circuit-proof and thermally protected
• Compact and lightweight; standard assembly fits in the palm of your hand
• High Sensitivity and very low self noise
• Proprietary sensor design and high-gain amplifier components give the user much higher sensitivity than many systems costing hundreds more.
• Quality low-noise preamplifier and power amp components keep hum and hiss to a minimum
• Integrated hydrophone sensor / preamp assembly and high-quality, low-mass cable minimize handling noise
• Easy to connect to PA, stereo or recording equipment
• Very power-efficient
• Low cost, simple to use and care for

The H2a hydrophone is the same transducer assembly used with other Aquarian Audio hydrophones, with a FET buffer preamp built into the hydrophone. It is designed to be compatible with electret-condenser microphone inputs that are found on many consumer and professional electronic devices. This makes the H2a an extremely versatile hydrophone because it can be connected to a broad array of devices without requiring a power supply or adjustments of its own.
The H2a offers true plug-and-play convenience with computer sound, minidisc, tape, and digital recorders. It can also be used with wireless lavaliere microphone transmitters and camcorders. Any device with a 3.5mm (mini) microphone jack is very likely to be compatible with the H2. Using appropriate adapter plugs, the H2a can also be used with wireless phones and radio transmitters.
The H2a is stocked in different lengths. Longer cable lengths can be custom ordered.
The H2a is also available with an XLR output. Phantom power is required.
Has a 3.5mm TRS output plug (miniJack).
Needs a "plug-in-power" connection.
Anything that works with a condenser microphone will work with this hydrophone also.
Manual with Specifications HERE
Custom cable lengths are available on request.
Please note: The 3.5mm TRS output plug is the only connector that will fit through a 1/4" NPT female mounting hole. If you intend to use the pipe mount and require an XLR connection to your preamp, contact us about installing a small pin connector inside of the XLR plug for solderless removal and replacement, or install 3.5mm TRS connector and use the H2a > XLR adapter.
Leave notes about your application so we can be sure to correctly install your cable and connector.

The H3 hydrophone was designed as a leak finding tool. It offers exceptional sensitivity in a very small size that can easily be inserted into plumbing systems. Additionally, its mechanically-balanced dual-element design minimizes acceleration noise. This helps lower handling noise and vibration-induced noise. The H3 is also used as a waterproof microphone in industrial applications where dust and coolants would make standard microphones unreliable.
The H3 hydrophone can be optionally assembled with our WT150g sliding stainless steel weight assembly for sinking the hydrophone. There are several advantages to placing the weight on the cable, rather than building it into the hydrophone. When the hydrophone is dropped, the cable flexes and deflects that impact away from the hydrophone. It also dampens vibrations in the cable that would be induced into the hydrophone signal as acceleration noise. The weight can be moved if needed to allow insertion into a pipe. These attributes are especially useful to the leak detection specialist.
The H3 offers the following advantages:
- Low cost
- Small size (16.5mm diameter)
- High sensitivity
- Robust, low-mass design provides high mechanical shock resistance
- Balanced element design minimizes acceleration noise
- Available in four different output configurations to interface with almost any microphone amp
- Compact (4.5mm OD) Low-noise cable with tough urethane jacket
- High dynamic range
- Low self noise
- One-year limited warranty
