Submersible Preamplifier

£1,464.00 excl. VAT

The submersible preamplifier is an essential part of the hydrophone signal as it buffers the signal and provides a 50 Ω source. It connects either directly to an interchangeable probe (‘HP’ series), or, if required, via a 20 dB in-line attenuator (A20/1).

More detail

Power is provided by the DC coupler (DCPS) so that the DC power and the acoustic signal share the same conductors in the interconnecting coaxial cable between the preamplifier and the coupler.
