Symposium Precision Rack


The Precision Rack is a "no holds barred" attempt to make the best support structure possible for our shelves. Instead of using more common construction techniques, using wood, or hollow metal tubes, the Precision Rack is made from solid rectangular bars of aircraft grade aluminum, precision cut, machined, and beautifully hand-polished.

 

 

We have heard the opinion that a rack isn't important- that the shelves, the footer devices, and those things that actually and directly contact the component are the only things that matter. Although we would agree that these have the most profound influence on the vibration treatment of the component in question, the support structure is also important, and for several reasons.

The rack, or frame, should be rigid and have excellent energy drainage characteristics, and the frame should be damped to discourage resonance. As we stress in the description and design of our platforms, energy drainage is of primary importance in the grand scheme of vibration control and isolation. Without it, energy remains trapped in the active circuitry to cause more signal distortion (spikes and cones function on this principle). Racks and stands which provide stopgap "isolation" schemes (with, for instance, rubber air balloons or sorbothane motor mounts), then disregard the drainage or sonic signature of the actual shelf, are making a bad problem worse. We have found, after years of experimentation and research, that the battle for vibration control is fought and won at the component itself . That is, the closer to the component you provide proper damping and isolation, the better will be the ultimate result . Whatever energy is left over should be conducted to ground as efficiently as possible. The rack, therefore, should be like a cone or spike- rigid and dense in order to provide for proper grounding of mechanical energy.

The Precision Rack was designed to allow for lots of space for your components. The bottom shelf boasts a generous 14 7/8" clearance (with Svelte shelves) to accommodate taller amplifiers with Rollerblocks or other special "footer" devices- and still leave plenty of airspace for adequate ventilation. The middle levels have lots of vertical space, too, so you can use Rollerblocks, Couplers, or other "footer" devices under your other components without clearance problems.
