Stereo power amplifier which pierced through the orthodox approach which the Marantz accumulated through the development of many high power amplifier, and was completed.
In order to obtain high power by a high quality, the power transistor with the especially excellent linearity is adopted. With the parallel three-step darlington circuit stream composition of four, a total of 16 power transistors are used.
Moreover, the reduction in a noise and a Low-noise-izing are attained, without realizing simple-ization, improving a nakedness property and applying a lot of NFB by adopting a cascode circuitry as all the voltage amplification stages.
The soy milk of a high regulation large-sized power transformer and the custom-made electrolytic capacitor for audios developed specially is carried out to the power-source part.
Especially the electrolytic capacitor adopted the high-class screw termination type of computer grade, and has acquired the high robustness.
The large-sized peek power meter is carried.
A logarithmic compression mold indication is adopted, and it can monitor, without switching a range from a very small output to the maximum output.
Moreover, as for the recovery time of meter, Normal/Peak Hold is switched by the switchpoint of the front panel.
The AC code to which remote which can control ON/OFF of the power source of power amplifier by the preamplifier side is attached is carried without letting a big electric current pass in a preamplifier directly.
The large current which serves as a noise source from the interior of the preamplifier which treats a weak signal by this is banished, and the influence on a tone quality is suppressed.
