Combining the features of the njm741 with the close parameter matching and tracking of a dual device on a monolithic chip results in unique. Any music as we know is in the form of a consistently varying frequency therefore when such a varying input is applied across the indicated c1 end terminals the same is delivered across the base t1 and ground. Ic 4558 is a monolithic integrated circuit designed for dual operational amplifier.
We recommend the low noise pre tone control circuit using 4558 instead.
The circuit is based on 2 4558 opamps with the main audio input and bass output volume adjustment. Power supply symmetrical 15vdc. Some of the text files within the pdf file. It was a very interesting ics because have special features of the low signal noise so commonly used in the high class amplifier.
