The ST191-DSA is perfect for laptop users! Small size, light weight, ruggedized high-impact case incorporates just the right combination of instrument quality connections.

The hot swappable/self-powered USB design utilizes a proprietary isolated, preconditioned, and regulated power supply scheme - optimized to maintain the highest signal integrity and performance regardless of environment. A buffered stereo output is provided to interface to the user system and the built-in high-quality headphone output is ideal for a truly professional monitoring experience in either record-capture/post-processing modes.

The ST191-DSA can be used with the Cetacean Research CR1 and other Cetacean Research Technology hydrophones, and is also sold separately. For a more advanced data acquisition interface, see the ST219-DAQ
