The Integrated Amplifier which adopted the design of separate amplifier SC-6 and SM-6.
Pure Class-A 30W+30W by the stream
composition of whole page perfect push pull DC. Freshness is high and switching
distortion etc. is the power which is not generated theoretically.
even a switchpoint comes out and a modification is also possible to AB class 120
W/ch. Since the difference of the sound by change is contracted, the high speed
high fT transistor which fully attained wide band-ization for cut-off frequency
with 90MHz is adopted as the power stage. Switching distortion called weak point
of AB class was suppressed to the relative minimum, and it is delicate and, and
yet, is finished in powerful AB class amplifier.
The control amplifier part also serves as a Low-TIM design with the power
amplifier part, and a nakedness property is improved by the material selected
carefully and the proficient circuitry. The amount of NF was reduced and
the distortion on Hearing impression was banished.
A power-source part is filled up with
the newly developed 22,000-micro F super audio capacitor and a special resin, and the compact transformer which took heat-resistant measures is adopted as it.
Furthermore, the heat pipe with high effectiveness was carried in the
heat-dissipation organization, and the high exothermic at the time of a pure
Class-A operation is cooled in it.
In order to raise the quality of a
disk play, the straight DC switchpoint to which phone amplifier is direct
connected to the power stage is equipped.
For this reason, the transistor which also attains to channel 13 stone
of one side is used for the Low-noise-izing of each block, a raise in an
S/N ratio, and MC head amplifier handling a detailed signal, and it polishes
even on the level which is fully worthy also as a single article.
Moreover, a phone input switchpoint is equipped with the cartridge
loading selector of 27kohm, 47kohm, and 100kohm, and any cartridges are
The design of a right-and-left independency is adopted as a tone control
circuit. Moreover, 2 point variable type is adopted as a loudness circuitry,
and two kinds, +8dB and +4dB, can be chosen as it in 100Hz.
Speaker change-over-switch loading in which a simultaneous play and a
change are possible.
Subsonic-Filter adoption which cuts unnecessary
