OVERVIEW
The SA12 is a phantom powered preamp that essentially creates an “electret hydrophone”. It draws power from a microphone jack, making it easy to connect a hydrophone to typical consumer recording devices such as a digital recorder or computer. It is ideal for underwater recordings and cetacean research within the audible range. Available in standard 25 dB and 15 dB configurations, the gain can be customized.
