Solve audio equipment vibrations problems with anti-vibration isolation pads

You can improve your systems performance with anti-vibration isolation pads and without big investment.  Structure-borne vibration have a serious impact on system performance that can be reduced. All you have to do is to place P4TO anti-vibration isolation pads under your equipment feet.

Material

Ring-porous wood is being used for manufacturing of anti-vibration isolation pads. After pyrolysis process in anoxic conditions under specific temperature, the chemical structures and cell wall components of wood is changed and, among other things, lignin, cellulose and hemicellulose are affected, so that the structure can absorb vibration, i.e., transform vibration into heat.

Usage

Anti-vibration isolation pads can be used under various equipment: CD, DAC, amplifiers, preamplifier, turntables, speakers, wires or other audio or video equipment.

Structure-borne Vibration

Unwanted structure-borne vibrations affect performance of all audio and video equipment. Reduction of these vibrations can significantly improve performance with better dynamics and better resolution. In most electronic designs, vibrations in the chassis are transmitted to the sensitive circuitry within. These vibrations are the cause of quite serious sonic aberrations that significantly limit the sonic potential of the component. Capacitors, in particular, are sensitive to mechanical vibrations. A few manufacturers attempt to control extraneous movements by gluing these parts to the circuit boards. This method, however, will only be effective if the circuit board has been effectively decoupled from the chassis. This usually is not the case.

Also components inside equipment like transformers in power amplifiers can generate vibration. If you have a power amplifier and a DAC or Turntable on the same rack or shelf, structure-borne vibration from the amplifier can reach more sensitive equipment.

Air-borne vibration

Speakers produce sound by moving air. Airwaves can affect such surfaces like shelf that your turntable sits on and can create structural vibration from this air-borne vibration. For this reason it is better to place speakers as far form equipment as possible. However, even then air-borne vibration can reach surfaces of racks and shelves. This is why separating equipment from the surface it sits on will improve performance by reducing air-borne or structure-borne vibration from the surface.

Measurements in laboratory

All measurements were made in anechoic chamber by using MLS signal and a 2-way loudspeaker was used as vibration “generator”. Measurements show response of a system under test in various conditions. Direct contact was measured with metal feet underneath loudspeaker. No contact was measured holding loudspeaker in hands suspended in air.
