The stereo Integrated Amplifier of W super scheme.
W and the super servo scheme which solved DC leakage to an output, the influence on the tone quality by the noise component resulting from source impedance, etc. are adopted as a power amplifier part.
Moreover, the super servo scheme of the super-low-pass cut is built also into the equalizer amplifier corresponding to MC.
Without fluctuating a bias entirely, the linearity of the circuit operation was raised and linear switching which suppresses crossover distortion is adopted.
Although it is B class operation which adopts, shares and amplifies two power transistors, the crossover skewness which tends to be generated at a wave-like joint by adopting a special corrective network is suppressed.
Furthermore, it has succeeded in the three-step Darlington stream composition of a High fT power transistor, and the thing which will carry out a double push pull and which it is alike and is banished more out of an audio frequency band also to switching distortion.
A MC-man month compatible variable gain equalizer and 2 amplifier stream compositions called only high gain power amplifier are adopted.
Equalizer amplifier is a development of the non it1 Capacitor-Less NF constant translation method by an electric-current translation super servo scheme which needs neither head amplifier nor a boost transformer even if it faces a using of MC cart,By the outstanding three-step differential amplifier of the nakedness property etc., it is being planned whether they are the improvement in S/N, and high gain.
Moreover, the power amplifier by W and a super servo scheme was raising the gain of 20dB, omitted tone amplifier and realized the wide dynamic range and the low distortion.
The softness circuitry is carried. Unlike the usual tone control, this circuitry can choose three kinds of different tone characters.
The large-sized power transformer of a twin whined scheme is used for a power-source part, and it is a chemicon for a rectification,The correlation of a careful hearing and the physical properties of a material is investigated, and the low impedance wide-range chemicon of a multi-tab scheme is used as the printed circuit board and a low inductance circuitry made to link directly.
Moreover, thorough low impedance-ization, such as using the hot bus (bus-bar) line made from a copperplate for a power feeding/power distribution of each section, and an earth line, is attained.
The direct tone scheme except the tone-quality failure with tone amplifier is adopted.
The difference of temperature by each part is detected, and the auto tracking bias scheme which enabled the always stabilized low-distortion drive is adopted.
In order to suppress an occurrence of a high order higher harmonic, it is the design of the tone-quality priority which uses non-magnetic-material material.
集成的立体声放大器的W超计划。
