1. With the Thorens New References, for the first time ever a turntable is designed and optimized from scratch together with a fully active vibration isolation system. Thorens teamed up with the German company Seismion, which is internationally renowned for its class-leading active vibration isolators, to create a turntable, that is designed around the vibration isolation system as an integral part of the system. Seismion fully exploited its expertise in active isolation systems used for semiconductor industry, nanotechnology and scientific laboratories, to create a vibration isolation never seen and experienced in turntables before.
The active vibration isolation is based on piezoelectric acceleration sensors with an extremely high sensitivity, and an all-linear electronic control circuit to generate unrivaled low noise- and distortion-free control forces. This sophisticated mechatronic system is based on so called Sky-Hook-Damping and isolates disturbances already below 1 Hz and reduces them to less than 1% (-40 dB) at frequencies of 10 Hz and above. Such a performance is far superior to any other isolation including a high-performance Air Spring. Especially at the critical frequencies around the resonance, the active isolation has a performance which is up to 100 times better. At 10 Hz it is still about 17 times better isolated than with an Air Spring. Other dampers like rubber mounts are on a much lower performance level and not shown in this comparison.
