The Isis Rack combines two innovative technologies pioneered by Symposium: the Svelte Shelf and the Rollerblock isolation system. The combination makes for a startling advance in rack technology.

Built-in Rollerblock isolation.

The Isis Rack features Symposium Rollerblock Isolation - not merely providing isolation of the shelf, but isolating the entire level (including the legs) from other levels while still maintaining a constant-density mechanical ground path (Patent Pending). It is interesting to note that two of the requirements for proper component support - isolation and mechanical grounding - are seemingly contradictory: this is the essence of the solution that the Rollerblock Module provides.

"Svelte Shelf" Technology

Symposium's popular "Svelte Shelf" has been considered an essential component by audiophiles for years, an accessory device that some have called "compulsory." The Svelte Shelf's constrained-layer stainless steel sandwich construction provides lower distortion and a rarely heard, coloration-free neutrality. Every Isis Shelf, Basic or Svelte, is supplied with 3 Precision Couplers, which provide exellent mechanical coupling between equipment chassis in order to make best use of the energy absorbing function of the Isis shelves.

Magnetic Bias technology

Magnetic Bias bearing technology (Patented) keeps the bearings of the Rollerblock isolator units conveniently centered while lifting or changing levels, and also provides a frictionless motional damping ("bias") during operation.

Build-as-you-go Modular design

The Isis is a modular system- you can start with just one or two levels and build up to multiple levels at your own pace. Change shelf spacing, isolation options, or type and number of shelves now or later - even shelf size can be changed.

Lightning Rods for Mechanical Energy!

The purpose of any rack's leg system should be to transmit energy to ground efficiently.The Isis system features solid legs of precision machined, aircraft aluminum - for unsurpassed mechanical grounding and sonic performance - and quality you don't get anywhere else. Wood legs and tubular metal legs, even when filled with sand or lead shot, cannot match the mechanical transmission capacity of the Isis' 1 7/8" diameter, solid aircraft aluminum leg sections.

EMI/RF "Faraday" shield design

Because of its shelf system construction, the Isis Rack system helps reduce distortion in sensitive components by providing RF/EMI shielding for your components. Multiple stainless steel layers form a "Faraday Shield" which reduces the harmful effects of EMI and RF, especially that which is generated by proximity to certain components, such as High Definition video receivers, which can emit higher amounts of EMI and RF energy. New Isis levels now have dedicated Ground Connection posts at the rear of each shelf for electrical connection between components and shelf, and shelf and dedicated electrical ground.



Shelf and Finish options
Choose several different shelf options, including Basic or Svelte Levels. All Isis shelves are precision laser-cut from polished stainless steel and are available in either standard 19x16 or heavy duty 21x19 sizes. Symposium also offers the "XL" (Xtended Level) 21x23" deep shelf for very deep components, a 24x20 Xtended Top or dedicated Turntable Tops with vertical damping for true state-of-the-art results with the finest front end transports and turntables. Choose from three different finishes, including deep black anodized, natural brush finish aluminium, or premium "Silver Edition."

Shelf spacing flexibility

The modular nature of the Isis Rack allows for different component spacings determined by the leg-set lengths of each section, and leg-sets can be swapped out to change spacing at any time. Custom leg-sets of virtually any length are available on special order.

High energy transmission reversible levelling spikes

Rack levelling through custom, heavy duty 1/2-20 threaded bottom spikes, reversible for hard floors or for carpets is made possible even when the rack is fully installed, with convenient orthogonal access holes. Spikes are made of the proper materials for excellent mechanical transfer through to mechanical ground (aircraft aluminum or optional Tellurium copper).
