Overview & Features
ASF-2 MKII Standalone Hydrophone Kit
The Standalone Hydrophone kit ASF-2 MKII is affordable, easy to use – and simply a great sounding hydrophone. Designed with key components used in the renowned ASF-1 MKII, the ASF-2 effectively utilizes the same professional hydrophone technology for outstanding underwater audio capture. With a frequency range of 70Hz-20kHz, we designed a microphone able to capture a perfect spectrum of sounds while effectively avoiding low frequency noise created by cable handling.
The Hydrophone Kit includes:
- Ambient ASF-2 MKII hydrophone with 10 mt of cable (optionally can be ordered with 15, 20 or 25 m)
- Zoom H5 Audio Recorder
- DT-770 Pro studio stereo headphones by beyerdynamic
- Watertight transport case
Hydrophone designed to withstand roughest conditions
The housing is machined out of high-quality aluminum with an anodized exterior for protection against the corrosive nature of seawater, while the 10m polyurethane cable is cast into the housing for a water-tight seal. These design attributes enable the ASF-2 Hydrophone to easily withstand the roughest field conditions. In addition to being an affordable hydrophone, the ground-breaking design of the ASF-2 is makes it affordable to operate as it is compatible with standard professional audio equipment.
Terminated with an XLR connector and powered by 48V Phantom, this plug-and-play hydrophone is designed for use with today’s professional field mixers and recorders for outstanding underwater recordings.
Never before has professional underwater audio capture been so affordable.
Zoom H5 Audio Recorder
The H5 is Zoom's newest recorder, offering the same substantially
improved low-noise, high-gain mic preamps as used in their flagship H6
multi-channel recorder. The H5 includes a unique interchangeable mic
capsule assembly and includes an X/Y capsule with advanced shock mounts
and 140dB capability. Five mic capsules are available, including
mid-side, shotgun and additional combination inputs.
Connect the highly-directional shotgun mic capsule for zooming in
on surface sounds while connecting one or more hydrophones to the XLR
inputs for simultaneous surface and underwater recording.
The H5 can also be used without an attached capsule, making it very
compact and rugged for use with only hydrophones or other external
signals. Battery life with two AA alkalines is rated at 16 hours. The H5
can also be used as a USB audio interface for doing real-time audio
analysis with your laptop or iPad. Truly an exceptional value in this
price range!
Sound from all channels is mixed to both earphones for listening by
default. You do not need to use the recording function to use the H5 as
an amplifier. Sound from the hydrophone is monitored in real time
through the headphones. Though the extent of recording features could
initially confuse non-audiophiles, the user interface is easy to learn
and it remembers your settings. The recording function can be used for
making voice notes (with attached mic capsule) or for customer
documentation or employee training. It is also economical to use with
its long battery life and support for NiMH rechargeable batteries.
