1.11 Connecting Hydrophones to 3.5mm TRS Mic Input of Other Audio
Devices
It is possible to connect the hydrophones of VT USA-168A/B to the 3.5mm TRS mic input
of other audio devices using a XLR to 3.5mm TRS adapter shown below. The adapter needs
to be purchased separately. It will allow you to use the hydrophone with any preamp
designed to work with electret-condenser microphones (i.e. with plug-in-power). The 3.5mm
plug is wired for dual-mono output, which will drive both left and right stereo channels and
is also compatible with mono computer sound cards.
