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.
