Integrated amplifier which investigated cost
performance for SU-V 10X with the base.
The ill effect from the output
stage resulting from the speaker load intensity which has adopted the stream
composition and is changed at the time of a real drive in the gain control
circuits which formed highly efficient operational amplifier in the predrive
stage is eliminated, and the distorted occurrence in the predrive stage itself
By carrying a power linear circuit, the linearity in an
output stage is improved and the high-definition speaker drive is realized.
The microcomputer has canceled the transitional distortion of an output
stage in real time by computer drive. Moreover, by linear feedback, the
independent feedback circuit which enables an infinite amplification is
constituted in a NFB loop, and distortion of an audible region is reduced.
Furthermore, switching distortion and crossover distortion are canceled by the
bias circuit made to become independent of a signal system.
transformer which is proud of a low loss and large capacity is carried in the
power-source part. An oxygen-free-high-conductivity-copper line is used for a
coil, and the regulation is sharply improved by adopting the original full sort
coil which can coil a bold line by a high-density 20% or more conventionally.
Very little low ESR (equivalent series resistance) type of a loss is adopted
as the power source capacitor for smooth.
The concentrated power block
which unified the output stage and the power-source part skillfully is adopted, and high ζc by electromagnetic radiation is canceled.
equalizer part serves as MC basic design.
The 2 steps of turnover change
functionality is carried in the tone control.
The video input
termination is carried and an interconnection of a composite signal is possible.
The image / voice-input termination is carried also in the front panel.
Apart from the source currently heard, the Lec mode selector which can
choose the sound-recording source freely is carried.
only for an external equipment convenient for an interconnection of a graphic
equalizer etc. is carried.
