Point Pods
 

Point Pods are an affordable solution for treating components with an effective, performance-improving vibration control device.

Description
The Point Pod is a slim, "mini" Symposium platform- only 2" by 3" (5 x 7.6 cm), and 0.315" (8 mm) thick. Their tops and bottoms are layers of hand finished, polished stainless steel, and their interior consists of 3 constrained layers of specially selected materials which damp and absorb mechanical energy with minimal reflection and time delay characteristics.


Application

Point Pods are ideal for use with small active components, such as mini-digital processors and power supplies, or with loudspeakers. They are also ideal for use with an inverted Rollerblock setup, as their stainless steel tops are hard enough for direct contact with the Rollerblock ball. Point Pods are most effective when used in direct contact with the chassis of components. In this primary application, they are effective either beneath or on top of the component, or both. They are also excellent for use when larger or taller isolation devices aren't appropriate or practical, as in equipment racks with limited vertical space. They are ideal for use on wood floors to protect spikes and cones from damaging surfaces, and can be used together with Symposium Precision Couplers or Rollerblocks to improve overall sonic results by providing a more neutral support surface. Point Pods are very effective with loudspeakers; in this application, they improve sonics by damping cabinet wall vibrations which cause loudspeaker driver intermodulation distortion.

SetUp
Use Point Pods as damping devices on small chassis devices; you will find them to be quite effective in improving dynamics, timbral character, etc. If you are STACKING components on top of one another, use Fat Padz to separate, isolate, and damp your components all at the same time!

Fat Padz

Fat Padz are stand-alone, vibration-absorbing devices which provide effective, "problem-free" resonance control and vibration damping with active and passive components. Compared to conventional cone-type isolation devices, Fat Padz are more tonally neutral, and more effective at reducing distortion, since they have the ability to dissipate energy as well as reduce the amount of new energy that can be introduced into the component from its support surface. They are more convenient and somewhat safer to use than cones, since they are physically more stable and cannot topple over.

Description
The Fat Pad is a mini Symposium platform- only 2" by 3" (5 x 7.6 cm), and 7/8" thick (2.2 cm) with tops and bottoms that are layers of precision laser-cut, polished stainless steel. Their interior consists of 3 constrained layers, including a 3/4" (1.9 cm) thick foam center section banded with textured vinyl edgebanding. The foam section is the same thickness as the Super Plus Platform. A Fat Pad can be considered an "expanded" Point Pod, since it is identical save for its thicker, banded foam center.
Application and Function
Fat Padz are convenient in situations where a full platform isn't practical. Their 7/8" (2.2 cm) height is enough to bypass most existing equipment feet, and should be used to directly support the metal chassis of active components. By coupling directly to the equipment chassis, Fat Padz damp excess mechanical energy from the component's structure, dissipating it as heat. By providing a non-resonant, non-compliant mechanical ground connection which simultaneously dissipates energy as heat (an important distinction to make over ordinary footer devices), Fat Padz reduce background noise induced in the electrical pathways of electronic and electro-acoustical devices.

Fat Padz also provide isolation from vibration originating in the support surface, such as a floor or rack shelf. They are very effective with loudspeakers, and can improve overall loudspeaker distortion levels by reducing intermodulation distortion caused by the reflection of mechanical energy to the drivers from the speaker cabinet.

Ideal For Stacked Components!
Fat Padz are ideal for stacked components; when convenience or room do not allow other deployments, Fat Padz are perfect as isolation and damping solutions for components which would otherwise simply sit on top of one another with their built-in feet. By placing Fat Padz in between the components, one will simultaneously damp both components AND isolate each one from another, improving results.

Placement and Set Up
Place Fat Padz as you would other "footer" devices. We recommend three, placed under the component so that the stainless steel top contacts the underside of the chassis, bypassing the rubber feet. If you're treating a small component, two may be sufficient. If possible, "butt" the edges of the top plate against any protruding screws, bolts, etc., as this will improve results.

Ultra Padz  - Maximum Isolation and Damping Power in a Discreet, Stable Pad
Ultra Padz are an alternative to a full platform, especially with heavy or very large components. As "smart" footers which provide greater damping and isolation than points or cone footer devices, their benefits exceed their modest cost!

Introduction
Ultra Padz are stand-alone, vibration-absorbing devices which provide effective, "problem-free" resonance control and vibration damping with active and passive components. Compared to conventional cone- and point-type footer devices, Ultra Padz are more tonally neutral and do not "spotlight" one band of frequencies or another. They are also more effective at reducing distortion, since they have the ability to dissipate energy as well as reduce the amount of new energy that can be introduced into the component from its support surface. They are convenient and safer to use than cones, since they are more stable and cannot topple over.

Description
The Ultra Pad is a mini Symposium platform-only 2" by 3" (5 x 7.6 cm), and 1 5/8" thick (4.1 cm) with tops and bottoms that are layers of high quality, precision laser-cut, polished stainless steel. Their interior section consists of 3 constrained layers, including a 1.5" (3.8 cm) thick foam center section banded with textured vinyl edgebanding. The foam section is identical to that used in the Ultra Platform. An Ultra Pad can be considered an "expanded" Fat Pad, since it is identical save for its thicker foam center.

Application
Ultra Padz are convenient in situations where a full platform isn't practical or possible. Their 1 5/8" (4.1 cm) height is enough to usually bypass even the most ostentatious built-in equipment feet, if desired, and can be used to directly contact the metal chassis of components or be used directly beneath the points of cones and ball devices for enhanced results with these types of footers. By coupling directly to the chassis, Ultra Padz damp excess mechanical energy from the component's structure, dissipating it as heat, and also provide effective isolation by simultaneously absorbing and dissipating energy which emanates from the support structure. By providing a non-resonant, non-compliant mechanical ground connection which simultaneously dissipates energy as heat (an important distinction to make over ordinary footer devices) from two directions at once, Ultra Padz provide effective, non-resonant isolation from midbass frequencies through the limits of hearing. Under cones and point devices, they will enhance and improve the performance of these footer devices by providing a superior mechanical ground interface.

Function
Ultra Padz also provide isolation from vibration originating in the support surface, such as a floor or rack shelf. They are also very effective with loudspeakers, and can improve overall loudspeaker distortion levels by reducing intermodulation distortion caused by the reflection of mechanical energy to the drivers from the speaker cabinet.

Ideal with Stacked Components
Ultra Padz are ideal for stacked components; when convenience or room do not allow other deployments, Ultra Padz are perfect as isolation and damping solutions for components which would otherwise simply sit on top of one another with their built-in feet. By placing Ultra Padz in between the components, one will simultaneously damp both components AND isolate each one from another, improving results.


What You Can Expect to Hear!
The proper deployment of Ultra Padz, whether under existing cones and feet or by themselves, provide better damped, expanded dynamics; a darker, quieter background with reduced noise; less "aggressive" or "edgy" upper midrange and treble region reproduction (caused by a reduction in noise products), and superior bass, with greater harmonic richness, greater separation between instruments, and an expanded virtual soundstage with more accurate timbral and transient resolution.

Precision Couplers

The Precision Coupler replaces our former Large Coupler to provide improved performance and convenience. Made of top-grade 7075 aircraft aluminum and precision machined to scintillating surface finishes, Precision Couplers are used to form an efficient mechanical connection to the components placed upon Symposium Platforms and Isis Rack levels, for effective damping of internal equipment resonances - an essential requirement for best results with vibration control devices. The high mechanical transmission efficiency of the aluminum alloy also provides an excellent transmission path for the evacuation of mechanical energy out of components and into a mechanical ground, where it can be absorbed and/or converted to heat energy.

All Symposium platforms work best with a good mechanical connection or pathway between the component's chassis and its top layer; soft materials, such as rubber or sorbothane, impede the transmission of mechanical energies. Think of the Precision Coupler as the mechanical equivalent of the theoretical "Straight Piece of Wire" in an electrical circuit: its sole purpose is to conduct mechanical energy without amplification, attenuation, or filtering. In this way, internal mechanical noise (vibration) can be conducted directly out of the component and into the Svelte Shelf, where these energies can be converted to harmless heat energy without added colorations. If your component already has built-in metal feet or has a flat bottom which will be placed directly upon the platform, or if you already have special footers for this purpose, then they are not necessary. Precision Couplers will not add any "harshness," will not exaggerate bass, or "spotlight" upper midrange. In other words, they are neutral. We recommend them if you don't have an alternate, suitable "footer" device, such as Symposium Rollerblocks, cones, or some other appropriate footer device.

Each Precision Coupler features nearly perfectly parallel top and bottom surfaces, and one side has a threaded 1/4-20 hole for attachment to similarly threaded foot posts or for screwing two Precision Couplers together to form one high coupler to clear very high feet. The Precision Coupler is 13/16" (0.8125" or 2.06cm) thick; two joined together form a double thickness unit that is 1 5/8" (1.625" or 4.12cm) high.

Precision Couplers may also be joined to the same 1/4-20 threaded hole found in Rollerblock Jr. devices in order to facilitate higher clearance requirements using Rollerblock Jr. In the picture at left, Precision Couplers were joined with Rollerblock Jr. to facilitate proper height of the turntable when deployed with its separate drive motor. Please click on image for larger picture.

The Precision Coupler's threaded hole may also be used as a receptacle for spikes and cones. Beyond protecting your floor or surface from the sharp point of a spike, the Coupler improves sound quality by damping the spike in an effective mechanical termination.

Each Coupler is 0.8125 inches high (13/16" or 2.06 cm) and 1.875" (4.76 cm) in diameter. For a further discussion of the Precision Coupler.

Super Couplers
Overview and Theory
Made from the same 7075 aluminum as the Precision Coupler and the Series 2 Rollerblock, the Precision Supercoupler borrows from Rollerblock technology to deliver improved coupling efficiency to surfaces for better energy transfer. Four Precision Supercouplers are supplied with the Quantum Platform. The performance potential of the Quantum demanded a leap forward in coupler technology, and the patented coupling technology of the Rollerblocks provides this advantage.

Hard Coat Anodizing
The Precision Supercoupler consists of a 0.8125" thick disc of hard coat anodized 7075 aircraft alloy aluminum which has been precision machined to nearly perfectly flat and parallel top and bottom surfaces. As in the Rollerblock, hard coat anodizing differs from the "garden variety" anodizing (usually black in color) found on most electronic components in that it causes a profound change in the hardness of the surface of the aluminum, creating a "skin" which is harder than most steels. Typical surface hardness with this process is on the order of chromium steel or greater; the ordinary black anodized finish (such as on CD players, etc.) is little more than a surface dye or coloration. The hard-coat skin of the Precision Supercoupler, as in the Rollerblock, serves two purposes: first, it constrain-layer damps the surface of the aluminum alloy body, making it less prone to self-resonance and making it appear harder to the interfacing surface, and second, it acts as a higher-density layer which enables faster transmission of mechanical energy, enabling better drainage of energy at higher frequencies. In principle, its purpose is to take advantage of mechanical "skin effect" at the higher frequencies of transmitted mechanical vibration.


The Matrix
The bottom of the Precision Supercoupler has a "matrix" pattern of holes, along with beveled edging. As in the Series 2 Rollerblock, this "matrix" serves both as a waveguide which enhances the penetration of mechanical energy into the support surface by presenting a more optimal angle interface (see the "Our Technology" section", but also increases contact pressure to the supporting surface, affecting superior energy transmission.

The Threaded 1/4-20 hole
Like the Precision Couplers and Rollerblock Jr., the top of the Precision Supercoupler has a hole threaded for a 1/4-20 thread, which is a very common thread for many posts and equipment feet. This hole, dead center, can serve several purposes: it allows threading to dedicated posts or anchors; it allows screwing two Precision SuperCouplers together (or to Rollerblock Jr., which have the same hole) for special coupling applications needing added height; or, the hole can be used as a receptacle for the tips of spikes and cones under racks and stands. In this last regard the Precision Supercoupler makes an ideal floor protector, since it not only protects floors but also provides a superb "termination" for vibratory energy exiting a rack or stand through its bottom spikes.

Deployment
SuperCouplers should be used like any footer device, to make a "bridge" between the bare chassis of the component and its mechanical ground, i.e. the shelf, platform, etc. In the case of the Quantum or Quantum Signature Platforms, one Precision Supercoupler should be placed on each of the Quantum's quadrant sections, thus coupling each section to a different part of the component's chassis. In all cases, the matrix side can face up or down.
