Infrasound vibrations in buildings and structures that are not perceived by the human ear, oscillations of wooden floors and floors can reach high levels, the operation of acoustic systems causes oscillations of the floor and racks with audio equipment, these vibrations penetrate into electronic components and speaker systems and distort the music signal. Isolation of audio equipment from the floor (in a general sense) is a prerequisite for realizing the potential of the audio component.The global experience of the scientific community and industrial laboratories has adopted pneumatic isolation of vibration-sensitive equipment as a standard. In no other laboratory will you see sensitive microscopes or micromanipulators on spikes or balls that can be found in the audio industry. The world of audio has long been ruled by marketing and beautiful spikes, multiple ceramic balls, beautifully packaged, easy to sell to trusting audiophiles. But laboratories and industrial enterprises are focused on results, so pneumatic isolation is chosen as vibration insulation of equipment around the world.

For the purposes of home and professional audio, Knecht Audio presented StandEcht Air Base pneumatic insulation platforms. The size of these platforms is 450*450 and 450*650 mm, which allows you to place them in any audio rack or on the floor. Inside these platforms there are 3 and 4 pneumatic cushions, respectively, which allows you to place equipment up to 150 and 250 kg, respectively. The large area of internal pneumatic cushions and the elasticity of the walls allow the insulator to function at low pressure (0.3-1 bar) and thus achieve malleability at low load on the platform, which gives a resonant frequency of this platform of about 3 Hz. This means that the platform as a low-pass filter will pass through oscillations below 3 Hz, and vibration with a frequency above the natural resonance frequency will decrease exponentially.

StandEcht insulation is used in conjunction with damper  DampEcht to achieve better vibration reduction of components. StandEcht Air Base insulation only separates the component from the vibrations following from the floor, and DampEcht allows you to extinguish the vibrations penetrating through the acoustic noises of the music being played and the internal vibrations of the components. Weight of StandEcht Air Base: 450*450 – 14 kg, 450*650 – 20 kg. Height 51 mm when pumped up. Stainless steel support surface: black, gray, polished. The main body is made of birch plywood covered with: transparent varnish, tinted and black varnish. You can choose any combination or request an individual color and finish. The platform comes with a template for leveling and a pump.
