The GEMINI Model-4 is an ideal power distributor combination for headphone systems or high-performance audio-video systems with 4 or fewer components. The onboard Chassis Grounding System only adds to the profound noise reduction.

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.

Note: The GEMINI Model-4 will be sold as a package that includes a 1.5 meter Venom HC v2 C15 power cable. 


DTCD logo

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.

NIC™ Technology

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.

CCI™ Noise Reduction

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.
