Audio Database MARK LEVINSON ML-7 1,180,000yen(1980 release) Description 　 It is the control amplifier which adopted as the amplifier circuitry the plug-in stream composition into which the module synopsis was developed. ML-7 consists of a main unit (ML-7) and a power-source part (PLS-154). The stream composition by a total of four plug-ins of two phone amplifier and two line amplifier is adopted. There was L3 plug-in of the high gain which can link MC cartridge directly as an option in phone amplifier.
