Aquarian Audio S1 Hydrophone
The S1 hydrophone is a modified version of the AS-1 hydrophone, manufactured by Aquarian since 2013. The S1 is designed to provide stable and linear broadband response within the range of frequencies supported by the best mass-produced audio recording devices.
It builds on the AS-1’s capability and convenience by supporting multiple in-built signal-conditioning options and two body styles. Integrated signal conditioning will generally improve sensitivity and lower noise, while making the hydrophone more convenient to use with standard devices.
Configurations:
| Signal Cond. Code | For Use With (additional details below) | Cable | Output | Product Code |
| S1e | Microphone preamps typically incorporated into higher-quality digital recorders, audio interfaces and mixing boards. 24 or 48-volt phantom power is required | CA-70 | XLR | S1eX |
| S1i | Microphone preamps typically found in more compact, lower-cost recorders. Also used with adapters for smart phones, single-board computers and their daughter boards (“hats” or “shields” for Raspberry Pi or Arduino and similar), compact USB sound dongles and more. | CA53 | 3.5mm TRS | S1iM |
Body Style:
S1e: The S1e standard output is XLR male, which will not pass through an M10 mounting hole. We solve this problem by modifying the XLR connector so that the contact pins can be removed during wire routing.
S1i: The low-profile 3.5mm connector that is used on the S1i will easily pass through an M10 mounting hole. No special considerations are required.
