Power Amplifier header
MTF-PA AmplifierGeoSpectrum Technologies offers low-noise, low-power amplifiers suitable for any of its hydrophones. The gain, bandwidth and filters can be set at time of manufacture. The output can either be voltage signalling or current signalling, the latter of which is recommended for longer cable lengths. These amplifiers are well-suited for streamers and other low-power applications.

GeoSpectrum Technologies currently offers the following Power Amplifiers:

M620 Power Amplifier

M620 Power AmplifierThe M620 Power Amplifier from GeoSpectrum Technologies includes a Crest Pro 200 Series Audio Amplifier. The assembly is housed inside a rugged rackmount rolling case. The front panel includes access to the power amplifier attenuation dials, as well as signal input/output connectors. See the specification sheet for more information.
