The Gemini Model-4 is the perfect solution for high-end headphone systems. Headphones are particularly sensitive to power line noise and ground plane noise. The Gemini Model-4 is relatively compact and fits nicely into smaller system racks. The Gemini Model-4 is a great solution for smaller office or bedroom systems where its dual functions can significantly improve performance without the complexity and cost of large power conditioners and expensive grounding systems.
The Gemini Model-4 is a unique product that is actually two devices in a single chassis. It includes both a high performance power conditioner and an advanced ground noise reduction hub. It features patented NIC™ noise isolation chamber technology that provides a common grounding point for all components and extends the Gemini’s noise reduction capabilities to all system components. This significantly reduces AC noise and voltage differences between chassis components that may help to reduce potential ground loops.
Technology
DTCD™ Analysis is a technique that measures instantaneous current through low impedance electrical conductors and contacts. Shunyata Research uses it to optimize the design, specification and construction of parts and materials to ensure maximum current delivery performance. Each part, conductor, noise circuit and material allows for maximum throughput of instantaneous current.
Listeners will experience earth-shaking low-frequency performance from even the highest-current amplifiers as well as dynamic contrasts unheard of outside of a live event. More than any other design parameter, Shunyata Research’s skill in eliminating resistance and maximizing peak-current delivery is unmatched.
The NIC™ ( Noise Isolation Chamber ) is a patented technology that reduces high frequency power line noise.
NICs™ use a non-reactive ferroelectric substance that actually absorbs high frequency noise. This reduces noise without any of the negatives associated with power filter coils, capacitors and transformers.

Traditional power conditioners are designed to block incoming noise from outside the home, but do not address the noise that is generated by the electronic components themselves. In fact, most conditioners reflect noise back into other components connected to the power conditioner. CCI™ ( Component-to-Component Isolation ) is one of the most significant but often overlooked aspects to power system performance. The CCI™ filter consists of a proprietary multi-stage filter that reduces electrical noise and interference generated by a component’s power supply.
CGS - Chassis Grounding System
The CGS ( Chassis Grounding System ) is an internal ground-buss that uses patented NIC™ technology to reduce ground plane noise. CGS provides a common grounding point and extends the noise reduction capability of the power conditioner’s internal Noise Isolation Chambers to other electronic components. CGS helps to minimize inter-component voltage differences between component chassis and may reduce the hum associated with ground loops while improving low-level resolution and clarity.
The system includes four terminals, that allows up to eight audio components to be connected.
We offer several models of CGC Ground Cables each made to your custom length and termination requirements.
ArNi® is a type of wire created by Shunyata Research designed to be the finest quality wire available for audio purposes. It begins with the highest purity of copper available – OFE C10100 or Ohno ( single crystal ). Then it is formed in virtual hollow tubes eliminating skin effects and eddy current distortions. In addition, the wire undergoes our proprietary KPIP™ process.

The GEMINI Model-8 rugged construction, dual zone AC filtering, 20A current capability and ground-noise reduction system is the perfect complement for high performance audio or video systems.
Gemini Model 8's onboard Chassis Grounding System complements the patented NIC chambers and multi-stage filtering capability, delivering unparalleled noise reduction and fidelity for any complete video, music or professional recording system. Whether for high current amps, subwoofers, recording consoles, or for the most delicate digital and analog sources, the Gemini Model 8's design insures maximum fidelity and system wide flexibility.
Notably, the GEMINI Model-8 is a full 20A high-current power distributor with a 20A IEC inlet, making it an indispensable asset for all customers aiming to optimize the performance of their entire music, video or recording system!
By deploying the GEMINI as your power distributor, you can expect a remarkable enhancement in both audio and video quality. However, when you engage the Grounding System (cables sold separately), the GEMINI transforms into a one-of-a-kind product, taking your system's performance to a whole new level, with noise-free operation.
To ensure impeccable fidelity, the GEMINI Model-8 offers four posts for chassis grounding only, further diminishing any unwanted noise that might affect your audio experience ( please note that signal grounding is not provided ).
Electromagnetic Breaker
Over-current protection is a requirement for today’s high current audio power distributors. The vast majority of manufacturers use an inexpensive thermal fuse or breaker. Both are specifically designed to heat up as the current level rises. This causes voltage drops, increased contact impedance, thermal noise, excessive heat generation and current limiting effects. There is a better solution — the hydraulic electromagnetic breaker that utilizes low-impedance relays and a sensing coil that reads the current level without heating up or limiting current. They can operate right up the to the maximum current level without heating up or limiting instantaneous current. They are rarely used in competitive products since they cost 10-20 times that of a common fuse or thermal breaker.
Power distributors react very similarly to power amplifiers in their sensitivity to vibration. Using the Shunyata vibration analyzer, Caelin Gabriel developed the Shunyata Isolation Footer, which possesses excellent measured vibration dampening characteristics. Shunyata Research also produces several SSF ( Stainless Steel Feet ) that employ energy absorbing polymers. ( Note: SSF feet are standard on some models and optionally available on others )
Cryogenic Processing
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.
