At the core of its design is the \"true dual-mono topology (left and right independent configuration),\" which treats each channel as a completely independent magnetic system. In conventional transformers, fine mutual interference between channels and magnetic field leakage are unavoidable. To thoroughly eliminate these, the 4x4 places fully balanced (differential) drive transformers independently for left and right channels. It establishes maximum-grade isolation (separation) both electrically and magnetically. This thorough \"isolation\" generates an unprecedentedly solid and clearly defined signal structure.\u003c\/p\u003e\n\u003ch4\u003e■ \"Floating Differential Transmission\" Achieving True Full-Balanced Drive\u003c\/h4\u003e\n\u003cp\u003eAlthough the 4x4 uses RCA inputs, it achieves complete internal balanced (differential) drive through its unique \"floating differential interface.\" The incoming signal is completely electrically separated from ground and transmitted to the primary side of the transformer as a symmetric positive-negative signal.

The priority here is not to add a particular timbre (character), but to maintain linear and highly reproducible magnetic behavior. Precisely controlled winding technology ensures vast bandwidth and highly accurate phase response, minimizing parasitic interference within the magnetic structure. Although the highly versatile RCA is used on the input side, the internal design is a \"floating differential interface\" (floating differential contact).
