MARK LEVINSON ML-7L 1,230,000yen(1980 release)

Control amplifier which adopted the stream composition by plug-in type block as a developed type of ML-1L in order to exceed the threshold of the conventional modular construction.

ML-7L consists of main-unit part ML-7L and power-source part PLS-154.

By having adopted several times as large a platform as a module, the freedom of the component-partses using improved sharply, and could give and design each circuitry for the margin, and the plug-in type block has realized the improvement in a performance.

Input selectors were arranged further and it has renewed circuitry by large-sized plug-in circuitry block. Moreover, low-impedance-ization is realized covering the whole signal path, it multiplies by the independent power supply by the remote-sensing scheme excellent in the regulation, and the descriptive power is raised.

There is an L3A plug-in of the high gain which can link MC cartridge directly in phone amplifier as an option.

Wooden cases are attached.
