Seismion - new active isolation platform from Germany
- Thread starter TLi
- Start date
I finally bought a 400mm x 500mm Seismion Reactio2 active vibration isolator, and I love the results.
Initially, there was a concerning evisceration of bass fundamentals essential for anchoring a stable foundation for music, but I quickly realized that it was part of the settling process which takes at least a few hours to complete. Thereafter, the truncation of the undesirable feedback loop (both airborne and structural) between the speakers and the DAC allowed my system to better resolve bass signals more discretely.
For my new basement listening room where most of my components will be placed on the ground between the two loudspeakers, the Reactio2 will no doubt be absolutely essential. I will for sure be buying a lot more of these!

The “Transport Lock” section on page 7 of the Reactio2’s owners' manual is unclear to me. Wished Seismion could restate the paragraph using bullet points, or sequential progressions "1), 2), 3), ...".
Are there any owners of the Reactio2 familiar with this function who can explain this better than what's provided? I'll need to check it in as baggage on my next flight, and I want to ensure that the unit won't be damaged in transit.
I'll also be sending them an email, and sharing the answers.

Dear XCop, thank you for posting the diagram from page 6 of the Reactio2's user manual. The problem still persists, as there is a discrepancy between the diagram, and the following sentence:
"...first take off all equipment placed on the isolator. Then turn the isolator off and afterwards on, by shortly pushing TWO TIMES the status button. Finally, long press the status button to activate the leveling."
Huh?
Nowhere in the diagram does it show what happens when (starting from the green isolation ON position) the status button is short-pressed twice, followed by a long press.
Something is still wrong with the way the paragraph is written on page 7. I've read it multiple times, but it simply does not jive with the diagram.

John, you don't need to worry about the manual.
If you want to lock the isolator, just turn it off by a long press to the power button. After a few seconds, you will notice the mechanism closing down and the platform lowers to a lock position.
To de-activate the lock, just press the power button again. Simple enough.
Other active isolation platforms like Herzan and Accurion have similar operation.
Hello QuadDiffuser,
sorry for late reply, but let me try to describe the procedure in more detail, and also the reason behind it:
1) remove all equipment from the top plate
2) shortly press the button to turn off active isolation (only if it was active before)
3) shortly press the button to turn on active isolation (which firstly performs an automatic levelling)
4) once the levelling is finished and the LED is green: long press on the button -> isolator performs locking procedure
5) once motors are stopped and LED blinks in red, you can remove the isolator from electrical power
You see you end up in the "short" - "short" - "long" operation of the button, which you also wrote.
The reason why you should not just do the long press is the following, and it makes in fact a difference:
During the locking procedure, the internal springs are compressed by some amount, so that the top-plate is pressed against the housing. I don't know the precise pressure, but let's say it is about 100 Newton (10 kg).
When you start the locking process while the isolator is levelled to the equipment weight, then these 100 Newtons are added to the already existing prestress, which counters the equipment weight. You can test it when you simply remove your device from the top-plate. Without new levelling, the top-plate would be then blocked against the housing. If the weight was 30 kg, then the blocking force would be nearly 300 Newton. And with the locking procedure, the force would be even 300+100=400 Newton.
Therefore, the isolator first needs to level to the unloaded case, and this is done by turning off (short click), and turning on again (short click) after the equipment is removed.
I hope this explanation is understandable, Otherwise please let me know.
Greetings,
Marcus
