Shunyata Research’s Hydra Sigma power distributor is the ultimate in the Performance Line of power conditioners. It builds upon twenty years of scientific research and development, patented technologies, and proprietary components that are simply unavailable in other products. The Hydra Sigma S12 features 12 outlets, patented NIC (Noise Isolation Chamber), MED filter technology, CopperCONN outlets, and the exclusive Cable Cradle that supports high-end power cables.
Shunyata Research has created its own vibration dampening solutions, after many years of research into its negative effects. Mechanical vibration can be very destructive to system performance. Our power conditioners are designed from inception to include advanced forms of vibration control that improve the recovery of subtle musical detail and nuance. All chassis panels and internal structures are treated with vibration dampening panels. Each outlet is isolated from the chassis with a vibration-dampening gasket that reduces vibration conducted through the AC cables. All internal modules, filters, and electronics are encapsulated in a vibration-absorbent compound.
Shunyata Research operates its own onsite Cryogenics International computer-controlled cryogenic plant. Liquid nitrogen is used to reduce the temperature of the contents to -320 degrees Fahrenheit. The computer monitors and lowers the temperature by a single degree at a time to prevent thermal shock.
We use this process to improve the performance of connectors and various electrical components that are used in our power products and signal cabling.
Over more than 2 decades, the reliability and durability of Shunyata Research products have become a legendary attribute of the brand. Shunyata products are completely non-reactive and run cool to the touch. They do not hum, vibrate, buzz, or generate heat and do not require any ventilation. Despite heavy-use applications in studios, medical labs, and home environments, Shunyata Research products maintain an almost zero failure rate. Many Shunyata Research products are covered under a limited lifetime warranty that can extend beyond the original purchaser.
In an era of products that are mass-produced, Shunyata Research invests in training career craftsmen who build our products by hand at our factory in Poulsbo, Washington. The exceptional fit, finish, and attention to detail have become a hallmark trait of Shunyata Research products going back to its inception in 1998. Shunyata Research has been building some of the finest power and cable products in the industry for more than twenty years. The commitment to building durable products that are designed to last a lifetime elevates our products to the top of their class.
Safety and quality control is job one at Shunyata Research. Before anything leaves the factory, we test each and every product thoroughly and carefully for safety and quality. This explains the long-term success of Shunyata Research products in the professional recording, medical, scientific, and consumer industries. Shunyata Research’s impeccable product safety and reliability track record for the past 23 years speaks for itself.
