Fresh off of our assembly line, these weeks Red Hot PCB features AFAB Enterprise’s latest version of their hydrophone preamp boards which are designed to provide signal conditioning when connecting the hydrophone to digital recorders, sound interface, or any test equipment.
These low noisePA4 hydrophone amplifiers can be phantom powered or used with external 6 to 12-volt DC power supply. The gain is user-adjustable from 6 to 56dB by jumper configuration and output wiring. There are several custom configurations that can be made to extend bandwidth, gain and power options.
Thanks to Robb from AFAB Enterprise for his contribution to this week’s Red Hot PCB.
