ML-7L
Commentary

This control amplifier uses a plug-in block configuration as an advanced version of the ML-1L to overcome the limitations of the conventional module structure.

The ML-7L consists of the main unit ML-7L and the power supply PLS-154.

The plug-in block has a board that is several times larger than the module, so the freedom of using parts is greatly improved, and each circuit can be designed with allowance, and performance is improved.

The input selectors have been further organized, and the circuit structure has been renewed with a large plug-in circuit block. In addition, low impedance has been realized over the entire signal path, and expression power has been improved by synergizing with the independent power supply by the remote sensing method with excellent regulation.

The phono amplifier has an optional high-gain L3A plug-in that can be connected directly to the MC cartridge.

Comes with a wooden case.
