MARK LEVINSON ML-6AL 1,960,000yen(1981 release)

Description
 
Control amplifier which attained perfect monophonic recording-ization based on ML-7L.

A cross interferencee is suppressed by considering it as 4 case structures where all control amplifier on either side was made to become independent of a power-source part (PLS-154L) on either side, and the improvement in a tone quality is aimed at.

The basic design has inherited the design concept of ML-7L, and has adopted the block structure by circuitry and the plug-in circuitry of only phone amplifier and line amplifier. Furthermore, one line of a phone and a line each accept an input, and it is also making a control into the simple structure of only a volume, and is planning whether it is the further high purity.

The decoupling capacitor of a power source is extended to the space which was vacant with simple-izing and monophonic-recording-izing of the circuitry.

Wooden cases are attached.

There were L3 plug-in card of the high gain only for MC cartridge and an L3A plug-in card in phone amplifier as an option.
