The Integrated Amplifier developed not aiming at a
technology but aiming at the sound near [ it is infinite to a human being's
sensitivity, and ] it for the technology.
Unlike a general high gain
equalizer stream composition, full-scale MC head amplifier with the
super-low-noise transistor selected carefully is carried.
Moreover, by the
high precision equalizer element and a whole page perfect push-pull circuit,
phone amplifier realizes a wide band and a low-noise, and also can enjoy the
play which employed efficiently the personality which each man-month cartridge
has with the Dolo selector.
The AB class DC power amplifier part puts into practice the Low-TIM design
original with a Marantz which suppresses dynamic distortion to the minimum
from the input stage of matched-pair dual FET to the output stage of a
three-step Darlington connection with a super high fT transistor.
The mass toroidal transformer and the super audio
capacitor are adopted as a power-source part.
The mic mixing circuitries
including both the tapeses dubbing functionality, and a phone and tuner compact
disk in which all sources and mixing are possible are carried.
