The Integrated Amplifier which Marantz U.S.A designed and carried out the checking up by the specification of Marantz U.S.A.
An equalizer part is a three-step hardwired-connection NF type which uses six stones of transistors, and, fundamentally, serves as the almost same circuitry as #7T.
A control of a mid range is possible for a tone control fraction. In consideration of the effect nature on Hearing impression, the control width of low and a quantity region is taken about twice compared with the mid range.
The main part has adopted the orthodox semi- complementary circuit.
A protection network is an ASO detection type, and also when an output is made to short-circuit by mistake interconnection etc., there is no care of flying a transistor.
It is the design which is not oscillated at all by the specification of Marantz even if it carries out the load intensity of the 10-micro F capacitor.
