Seismion is thrilled to annouce the all-new Reactio 2 active vibration isolator. It is the consequent advancement from the original Reactio and the Reactio plus. The Seismion Reactio 2 is a professional tool for perfect vibration isolation without compromises. It was developed with the toughest criteria both from the high-end audio field as well as industrial use in metrology and semiconductor production. It features an exceptional isolation performance starting in the sub-Hertz range, in a totally new housing.
It features the following key specifications and improvements compared to our already highly successful Reactio plus:
- Excellent isolation performance
only a very exclusive circle of active vibration isolators is capable of such a performance. It not only efficiently isolates vibrations even in the very low frequency range, it also only adds minimal electronic noise due to selected electronics and sensors. As a result, the Reactio 2 achieves an exceptionally low vibration level
- Fully automatic leveling functionality
the Reactio 2 includes several deflection sensors and motors. By automatic leveling it is assured that the top-plate is always perfectly aligned with a repeatability of up to 25 µm. By that, the sensors and actuators always operate under optimal conditions
with a push on the button, the top-plate can be locked against the housing. By that also the passive isolation is eliminated, and delicate equipment like turntables can be setup
- Differential measurement technology
the vibration sensors of our Reactio isolators are designed with the differential measurement technology. By that, their susceptibility to interferences is greatly reduced compared to single-ended technology, which is the standard in industry
- 2x better noise performance than the former Reactio plus
the total noise generation is simulated by sophistical computer models, and with a selected choice of Operational Amplifiers the noise floor could be reduced even further. Ther result is a perfectly clean and silent background
- Higher passive resonance damping of top- and bottom-plates
for additional passive damping especially at higher frequencies, the top- and bottom-plates are now made of MDF fiberboards
- design optimized for high-end audio usage
high-quality push button, DC-connector and housing, all our isolators are hand-finished in our production site in Hannover, Germany. We only use highest quality components and a perfect finish
- Active vibration isolation and stabilization
Audiophiles strive for the perfect reproduction of recorded music. Vibrations are sound, and sound is vibrations. This becomes particularly evident with the sound pickup of turntables. At that level, it becomes impossible to distinguish between parasitic vibrations and the actual music information stored in the grooves. Furthermore, many other components, such as vacuum tubes, are microphonic, meaning external vibrations directly degrade the output signal.
Therefore, disturbing influences must be eliminated throughout the entire audio chain. The Seismion Reactio 2 brings you closer to that goal than ever before through the power of active isolation
(the advantage of active isolation).
