Ultra compact! Plug-type virtual grounding (ground terminal)!

This is an ultra-compact virtual grounding (ground terminal) that has succeeded in increasing the surface area of the conductor by an original and epoch-making method, making full use of the knowledge and know-how of virtual grounding that we have cultivated up to now.

The lineup of plug shapes includes RCA plugs, banana plugs, φ3.5 stereo mini plugs, and Y-plugs. Other plug shapes are planned to be commercialized in the future.

The various plugs are gold-plated for reliability and performance, and the body and cap of the virtual grounding section are sandblasted with a pear-finish finish to expand the effective surface area of the metal conductor and to integrate it with the design.
