Audiav Grandmaster Signature Designer Line. Custom world leading co-designed products with Audiav Furniture & Minus K Technology: Use the same cutting-edge technology that 1000's of research facilities, hospitals and the elite scientific community's benchmark product has to offer! These designs have been used with sensitive audio technologies, electron microscopes, laser systems, micro-engineering fabrication, genetics, military and many other research applications. Incorporating the finest technologies inside an Audiav design can seamlessly blend the ultra-high-tech with exquisite home decor. How it Works: Vibration isolators employ a revolutionary concept in low-frequency vibration isolation. Vertical-motion isolation is provided by a stiff spring that supports a weight load, combined with a negative-stiffness mechanism (NSM). The net vertical stiffness is made very low without affecting the static load-supporting capability of the spring. Beam-columns connected in series with the vertical-motion isolator provide horizontal-motion isolation. The horizontal stiffness of the beam-columns is reduced by the "beam-column" effect. (A beam-column behaves as a spring combined with an NSM.) The result is a compact passive isolator capable of very low vertical and horizontal natural frequencies and very high internal structural frequencies. Designs typically use three isolators stacked in series: a tilt-motion isolator on top of a horizontal-motion isolator on top of a vertical-motion isolator. A vertical-motion isolator is shown in Figure 1. It uses a conventional spring connected to an NSM consisting of two bars hinged at the center, supported at their outer ends on pivots, and loaded in compression by forces P. The spring is compressed by weight W to the operating position of the isolator, as shown in Figure 1. The stiffness of the isolator is K=KS-KN where KS is the spring stiffness and KN is the magnitude of a negative stiffness which is a function of the length of the bars and the load P. The isolator stiffness can be made to approach zero while the spring supports the weight W. A horizontal-motion isolation system consisting of two beam-column isolators is shown in Figure 2. Each isolator behaves like two fixed-free beam columns loaded axially by a weight load W. Without the weight load the beam-columns have horizontal stiffness KS. With the weight load the lateral bending stiffness is reduced by the "beam-column" effect. This behavior is equivalent to a horizontal spring combined with an NSM so that the horizontal stiffness is K=KS-KN, and KN is the magnitude of the beam-column effect. Horizontal stiffness can be made to approach zero by loading the beam-columns to approach their critical buckling load.             Figure 3 shows a schematic of a Series SP-1 vibration isolation platform consisting of a weighted platform supported by a Series SM-1 vibration isolator incorporating the isolators of Figures 1 and 2. Flexures are used in place of the hinged bars shown in Figure 1. A tilt flexure serves as the tilt-motion isolator. A vertical stiffness adjustment screw is used to adjust the compression force on the negative-stiffness flexures thereby changing the vertical stiffness. A vertical load adjustment screw is used to adjust for varying weight loads by raising or lowering the base of the support spring to keep the flexures in their straight, unbent operating position. This feature is automated in single-isolator systems and to achieve automatic leveling in multiple-isolator systems. Please contact Audiav on the Contact Us or a Dealer for more information. Audiav's Diamond Series clients are hell-bent on the finest sounding performance furniture available anywhere in the World, with a look that constantly exudes luxury.   Diamond racks have a world-class performance benchmark. The world's most advanced isolation, presented in a unique powerful style, and a luxurious appearance that gives your sensitive reference components a proper place in the most sophisticated of environments. The Diamond Series* by Audiav is the World's only true performance piece, with the option to have a co-designed Audiav and Minus K supreme isolation platform "built in". The A-Line Specialty platform series can separate the men from the boys. A-Line platforms are the best performing isolation platforms available anywhere and at any price. This jointly designed system meshes the finest technology with home decor appeal. NOTE: Very tall / heavy equipment is recommended or the rack will easily "swallow" your smaller components in proportion. The Diamond Series has a way of making even larger amps look wimpy and small.  *Available with optional channel set gemstones or genuine carbon fiber inserts. *Available with "A-Line" Audiav Designer Line Platforms between a joint engineering agreement model with Minus K.
