Sagamihara-city, Kanagawa, Japan  |  2023 – Soulnote A-3 Launch! Technology Complete separation of left and right channel GNDs The GND separation technology incorporated in the P-3 pre-amplifier is applied to this model with a power amplification circuit. Originally, how to ground the GND of a power amplifier that handles high current to the chassis was a key design issue, and there is no precedent for GND non-grounding. However, ungrounding of the power amplifier’s enclosure was achieved through simple non-NFB circuits, optimized artwork design, minimization of high current loops, elimination of inductance components,…
