Ambient ASF-1 MKII – Hydrophone
The professional Ambient Hydrophone
Crystal clear, low noise audio from infra- to ultrasound
The ASF-1 MKII is completely designed and manufactured by Ambient Recording in response
all the requests for an affordable, yet professional hydrophone for working with standard
audio gear. The goal was nothing less than to create a very natural sounding, low noise
underwater microphone. Well, it took us nearly 3 years but finally we did it.
With the development of the Ambient “Sound Fish” we focused on high audio quality with
best handling. Therefore we designed a linear, low distortion microphone preamp offering
a linear frequency response from 10Hz- 40kHz.
Waterproof up to 100m
Following our idea to create an underwater microphone for professional sound recordists
we worked hard to build a hydrophone which can be fed directly from standard 48V Phantom power.
Thus, this microphone works right out of the box with all your existing audio gear
without additional adaptors. The ASF-1 MKII is machined out of high quality aluminum-brass
and can easily withstand the water pressure of 100m depth.
Additionally the used materials (special formulated NBR, polyurethane cable) stand out for
their long term resistance against seawater. Within the purchased parts package we
included a 10 meter underwater cable with sealed AHS underwater connector.
Thus, the AFS-1 MKII can be used right out of the box without additional adaptors or cables.
Other cable lengths are available on request.
