The Ambient Recording ASF-2 MKII Hydrophone is an affordable, easy to use, great-sounding hydrophone. Designed with key components used in the renowned ASF-1 MKII, the ASF-2 MKII effectively utilizes the same professional hydrophone technology for outstanding underwater audio capture.

With a frequency range of 70 Hz to 20 kHz, the company designed a microphone able to capture a perfect spectrum of sounds while effectively avoiding low-frequency noise created by cable handling.

The housing is machined out of high-quality aluminum with an anodized exterior for protection against the corrosive nature of seawater, while the 33' polyurethane cable is cast into the housing for a water-tight seal. These design attributes enable the ASF-2 MKII Hydrophone to easily withstand the roughest field conditions. In addition to being an affordable hydrophone, the ground-breaking design of the ASF-2 MKII 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.

Related Questions and Answers

Q: 1. Is it Mono or Stereo?

A: The Ambient Recording Soundfish 2 MKII Compact Hydrophone with Cable is mono.

Q: 2. a recommended distribution amplifier that share TC and genlock with one cable please?

A: A recommended distribution amplifier that could share TC and genlock with one cable on the Ambient Recording ACN-CL Lockit Compact Wireless Timecode Synchronizer would be the AJA C10DA Analog BNC 1x6 Distribution Amplifier, B&H # AJC10DA.

Q: 3. What is the relevance of genlock sync at 1080p or 1080i, can someone elaborate, why does it matter?

A: Cameras can be either set to progressive (p) or interlaced (i) recording format. Depending on the chosen format there is the need for an adapted genlock signal. Ambient Recording ACN-CL Lockit Compact Wireless Timecode Synchronizer are able to provide either p or i. So regardless the recording format all cameras are able to be synced wirelessly.

Q: 4. Can I use this mike on an iPhone?

A: The Ambient Recording ATM216 Tiny Mike Miniature Electret Shotgun Microphone for DSLR Cameras (B&H # AMATM216DSLR) will work on an iPhone with the proper 3.5mm (1/8") adapter.

Q: 5. can I use a split cable to genlock 2 cameras ? Or do I need to devises ?

A: No, you can not split the output from the Ambient Recording ACN-CL Lockit Compact Wireless Synchronizer to sync multiple cameras at once.

Q: 6. Is this unit waterproof?

A: Yes, the Ambient Recording Soundfish 2 MKII Compact Hydrophone is waterproof.

Q: 7. for virtual production volumes, can the device be synchronized to an evertz 5700 and then run standalone as a timecode and genlock generator on camera? also maintaining genlock that would normally come from evertz?

A: With the LTC output of the Evertz 5700, you can sync the Ambient Recording ACN-CL Lockit Compact Wireless Timecode Synchronizer in TX mode. As a TX master, the Lockit will adapt to the speed of the LTC signal, and it will regenerate and broadcast the time code and sync to all of the following ACN units. For virtual productions, I would recommend using the Lockit+ (B&H # AMACNLPE) as the TX master as it gives you more insights about the current sync status in its web interface.

Q: 8. What's the different between the MkII and the original ASF-1?

A: The molding around the case of the mic has been redesigned.

Q: 9. Will this device accept an SDI signal as a genlock input, broadcast this over ACN, and output a wordclock referenced to it? I see lots of discussion of genlock output, but not input. I have a camera without genlock, and I want to avoid pops when combining HDMI + AES - SDI. Therefore I want to synchronize the audio ADC to the un-genlockable camera.

A: no this device will not work as a genlock for a camera without genlock, it's base/fundamental mode of synchronization is time code

Q: 10. What's the difference between this and 'ASF-1 MKII'? Does the ASF sound better fidelity wise? Thanks!

A: The Ambient Recording Soundfish ASF-2 MKII Compact Hydrophone has an omnidirectional polar pattern with a frequency response range of 70 Hz to 20 kHz, a total harmonic distortion rating of 0.1%, and the dimensions are 1.9 x 1.2 x 1.2" (47 x 30 x 30 mm). The ASF-2 MKII can be used for underwater applications up to 100' (30 m). The Ambient Recording Sound Fish ASF-1 MKII Hydrophone has an omnidirectional polar pattern with a wide frequency response range of 7 Hz to 40 kHz, a total harmonic distortion rating of 0.1%, and the dimensions are 6.9 x 1.0 x 1.0" (175 x 26 x 26 mm). The ASF-1 MKII can be used for underwater applications up to 328.1' (100 m). Physically, the ASF-1 MKII is a larger and longer microphone with a thicker cable than the AFS-2 MKII, and the AFS-1 MKII can be submerged to a much farther depth than the AFS-2 MKII. The AFS-1 MKII also has a much wider frequency response range than the AFS-2 MKII.
