PAB anti-vibration platform handling manual

PAB anti-vibration table with suspended shelves handling manual

The platform is supplied ready to use, however some initial setup is required:

• levelling of the plinth (in the newest models by turning the feet and countering them);
• rising and levelling of the shelf using the tensioners for the strings mounted in the plinth (the shelf is risen by turning the keys clockwise, and lowered by turning them in the opposite direction).

Before the electronic equipment is placed on the shelf we advise to check, if the strings are secured on the pulleys in the funnels, by removing the caps of the columns (this needs only be done for older platforms, newer ones are constructed in a way, that prevents the strings to fall off the pulleys).

After placing the equipment it may happen, that despite previous levelling, the shelf tilts, or even touches the platform (your device can be heavier on one side, or heavier than the maximum load of the platform). In such case you need to tension one or more strings, lifting the device by hand, to minimize the stress on the strings, especially its sheering on the edge of the hole in the plinth, where its guide rail is bent. Attention: in case the device is heavier than the maximum load it should not be placed on the shelf, as it may tear the strings or damage the tensioning mechanism; in such case please contact us immediately.

After a few hours of use, the strings may extend if the load is higher than indicated above, and the shelf may touch the base. If this happens, all strings need to be tightened so that the shelf can swing freely (unhindered movement of the shelf above the base is essential for the platform to operate correctly). Usually this lifting and leveling the shelf again is the final one. However with very heavy devices, with a weight close to the maximum load of the platform, it may become necessary to repeat the whole procedure.

Please avoid placing more than one unit on a single platform. Otherwise, the platform may become overloaded, which will inhibit its resonance damping properties (partly due to the mutual interaction of vibrations inherent in each of the units).

When operated correctly, PAB platforms will last a lifetime. However, since the strings that are a critical component of the product may break, we provide a set of spare strings and PVC tubes with each platform (the tubes protect the holes in the support columns, and are subject to normal wear).

To replace a broken string, proceed as follows:

• remove the electronic unit from the shelf;
• secure the shelf and the base against damage;
• loosen the remaining strings so that the shelf rests on the base;
• remove the broken section of the string from the shelf pin;
• place the platform upside down by putting it on top of the shelf;
• remove the other end of the string from the column and the tension screw;
• guide the replacement string through the PVC tube so that you can grab its end after inverting the platform. ATTENTION: The mounting screw at the bottom of the platform must not be unscrewed, as it will cause the load-bearing assembly to fall apart, and will void the five year warranty for the product;
• pull the string through the hole in the tension screw, and tie a knot at the end (heat both ends of the string with a lighter to prevent the knot from untying);
• place the platform the right way up, and place it on its feet;
• guide the string through the pulley and the oval opening in the funnel and tie a knot that will tighten under load and heat the end of the string with a lighter;
• loop the string around the shelf pin and tighten it;
• lift the shelf to the appropriate height and level it using the tensioners;
• place the electronic unit on the shelf.

All PAB anti-vibration platforms with string suspended shelves work in the same way, therefore handling is similar in all cases. While PAB monitor AVP and PAB reference AVP appear different, they are merely inverted, and have an extra shelf installed on top to cover the support column attachment points that extend upwards and to accommodate monitor speakers of various sizes, while the second kind has an inverted PAB basic AVP inside.

If you do not want to repair a platform by yourself, please send it to us. We will repair it free of costs, you will only need to cover transportations fees both ways.

The table is supplied ready to use, however some initial setup is required:

• removal of the transportation wheels and fastening of the PAB anti-vibration feet;
• levelling of the table top by turning the feet and countering them.

Raising and levelling of the shelves for the electronic equipment using the supplied PAB key, inserted in holes in the metal sheets, which cover the modified tensioners (the strings should be tightened equally, turning the key a few times, so that the shelf is not overly tilted. The shelf should be supported by hand while doing so, to minimize stress on the strings).

After some time it may happen, that despite previous levelling, the shelves tilt to one side or rest on their bolts (this may happen, when the device is heavier on one side, or its weight is close to the maximum load of the shelf, 42-56 kg). In such case some or all strings need to be tightened again, after supporting the shelf by hand, to minimize the stress on the string, especially where it crosses the edge of the hole in the crossbar, to which the tensioner is mounted (in the newest version of the table this is no longer necessary, as a special transmission mechanism was employed, which eliminates the contact of the string with non-moving surfaces and decreasing its friction). Unhindered movement of the shelves in the PAB table is essential for its function, as it is for all the PAB anti-vibration platforms.

Please avoid placing more than one unit on a single platform. Otherwise, the platform may become overloaded, which will inhibit its resonance damping properties (partly due to the mutual interaction of vibrations inherent in each of the units).

The massive and large table top can be used for placing a turntable or very heavy amplifiers. It can stand a load of 160 kg, if appropriate PAB anti-vibration feet are used.

When operated correctly, PAB platforms will last a lifetime. However, since the strings that are a critical component of the product may break after big overload of the shelves (for example after violent positioning of the electronic equipment or when somebody supports his or her weight on them), we provide a set of spare strings and PVC tubes with each platform (the tubes protect the holes in the support columns, and are subject to normal wear).

Replacement of a broken string is easy. Below are the steps to be followed:

• remove the electronic devices from the shelf and the table top;
• lower the shelf with the broken string so that it is supported by the bolts;
• remove the aluminum sheets covering the mechanisms in the table leg (using one of the supplied keys);
• remove the broken string from the bolt in the shelf;
• remove the rest of the string from the opening in the bolt of the tensioner;
• place the new string over the pulley (Attention: if this cannot be done on the hanging pulley, then remove the two bolts holding its enclosure, remove it, and after placing the string reassemble it);
• make a self-tightening knot on one end of the string and put on the bolt of the shelf (please heat the end of the string with a lighter to prevent untying first);
• lead the second part of the string through the PVC tube (if the tube is damaged ? eg. crushed or cracked ? it should also be exchanged);
• lead the string through the hole in the bolt of the tensioner, tighten a knot on its end and heat that end with a lighter;
• place the electronic devices on the shelf;
• rise and level the shelves on appropriate height using the PAB key for the tensioners (Attention: the shelves rise, when the key is turned clockwise);
• use the table for a few hours and the adjust the shelves again (especially the one with the new string);
• place the cover sheets.

Do not remove the bolts from the shelves at no occasion! This would result in widening of the openings in the shelves and increase the vibration of the bolts after placing them again, what would greatly diminish the anti-vibration abilities of the table.
