Platis 65

Record players literally measure vibration, which obviously makes them extraordinarily sensitive to external, microphonic interference. What is less obvious is the vulnerability of all audio electronics to mechanical vibration. Noise coming through the structure of the building, the floor, from other audio components or from just playing music impact the component’s housing and vibrate the sensitive electronics inside, masking or blurring the signal. The affects may be less apparent than with a turntable, but they are no less destructive to the sense and enjoyment of the musical signal.

To minimise this microphonic influence, components must be isolated from the room and each other via independent isolation platforms, used in conjunction with equipment stands or shelves. Using an incredibly sensitive vibrometer, we have analysed the interface between equipment and its supporting surface and developed our PLATIS isolation platform.

PLATIS 54 and PLATIS 65 are passive isolation platforms that filter structural vibrations and prevent them reaching sensitive audio components. The base frame is milled from solid aluminium, and provides locating tracks for the multi layered silicone and aluminium dampers so that they can be positioned to optimally support each component. In conjunction with the composite aluminium laminated top plate, these effectively filter vibration throughout the audible range. Adjustable feet also ensure that you can level each component independently, irrespective of its weight distribution, a crucial concern in both isolation and audio performance terms that is often overlooked when a whole system is installed in a single rack.

Upper plate and lower frame are separated by multi layer silicone & aluminium dampers which filter vibration in audible range.  See DEWESOFT  graph photo measured with DEWESOFT system:
