Simply connect your MC cartridge with a standard RCA phono cable, and internally, the signal is treated as a balanced waveform, allowing you to extract the benefits of symmetrical transmission identical to higher-end units with the shortest signal path without reconfiguring the system.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0612\/9139\/7377\/files\/pa.jpg?v=1781165140\" alt=\"\"\u003e\u003c\/p\u003e\n\u003c!-- 画像挿入：Pacto 本体（フロント） --\u003e\n\u003ch3\u003e\u003cstrong\u003eThe true value of Quatvol for your RCA system\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003e\"With just RCA, the interior is perfectly balanced.\"\u003c\/b\u003e At the heart of Pacto is a fully balanced circuit designed identical to that of high-end models. The floating differential input instantly detaches signals incoming from RCA from the ground and internally converts them into symmetrical transmission.
