The Integrated Amplifier which polished a function and the engine performance and was crowded as a component of CD age.
What has improved the dual
super unreturned circuit further, and raised the slew-rate characteristic is
adopted as a power stage.
In the output stage, it has three-step
Darlington push pull composition which uses the high speed and mass power
transistor of more than fT50MHz and Pc150W.
Moreover, it has
perfect direct-current composition which uses not a coupling condenser for all
the signal courses between speaker output terminals from MC input terminal by
direct-current servo circuit,The new current mirror circuit and interval of high
speed transistor adoption of fT250MHz excellent in a non-feedback system without
signal return and the high region characteristic have realized the high slew
Transformer [ of 220VA ] and block condenser 32,800micro F for
audios (8,200micro-Fx4) etc. is adopted as a power-source part.
generating of low-pass distortion is reduction-ized by setup of the floating
load circuit which clarified ground electric potential.
quality degradation which considers ripple current as a cause is sharply
improved by adoption of a newly developed pure dynamic power supply circuit.
The super equalizer constituted from the low-noise FET differential
amplification first rank has attained the wide-range characteristic of RIAA
deflection 20Hz-100kHz}0.3dB (at the time of MC).
In order to correspond
to a surround processor, a graphic equalizer, a channel divider, etc., the
circuit for connection "processor loop" is equipped.
terminal is adopted as a Phono input terminal.
Broadband real-time tone
control and a Subsonic Filter are carried.
