Description

The model changed the model and developed as the 5th phase of C-200 series.
On the basis of all the magnification stage push pull drives, it consists of dregs cord Buu and a strap complimentary Class-A push pull circuit.

The inputs of the composition of amplifier are constant current load, and dregs cord Buu and an FET buffer input with a strap,Power is demonstrated to reduction of a weight noise, and low distortion-ization, and then the Darlington Class-A push pull of an output is driven by the dregs cord Class-A differential push pull and the dregs cord Class-A push pull.
The feature of dregs cord connection has little feedback during input and output, and is that the good characteristic is acquired especially in a high region. Moreover, a profit is large, a linearity is maintained to the operating limits of an element, distortion decreases, and S/N is improved.
Furthermore, the important power-source part has arranged and strengthened the full-scale constant-voltage power supply circuit on right-and-left channel each substrate.

Equalizer amplifier is carried in order to correspond to playback of an analog disc.
Although the system which changes a profit is adopted, the change of MC/MM prepared the exclusive input circuit united with the characteristic of each cartridge, changed it simultaneously, and has obtained the engine performance which matches at the time of the head amplifier use only for MC.
Moreover, by the impedance of MC cartridge, the MC LOAD change which chooses load resistance is carried, and it can choose out of three kinds, 10, 30, and 100ohm.
Furthermore, the power-source part is strengthened with equipping a full-scale constant-voltage power source.

The straight signal course consists of the shortest in changing by controlling a relay electronically in a logic circuit by functions, such as an input change and a tape monitor, in order to suppress degradation of the sound quality cut with taking about a signal course.
The relay only for an audio of an encapsulated type is used for a relay, and durability is raised reliability and over a long period of time.

The presence equalizer is carried for equalization of a program.
Considered so that music expression can be adjusted most effectively, the variable range of frequency has become six kinds 4 point.
The inside compass is 500Hz and 2kHz in center frequency, and 500Hz controls 2kHz of attitude of vocal to expression of a rhythm musical instrument again. The value which determines the sharpness of a crest has chosen the value from which the most natural change is obtained from the audition result of program sauce.
It is possible for low-pitched sound and the loud sound to be able to choose two kinds of frequency, respectively, and to adjust whole energy balance and atmosphere.
The presence equalizer is constituted from combination of an added type filter, and an element also thinks sound quality as important and is selecting it carefully.
Moreover, the presence equalizer is considered so that it may separate from a signal course in the state of OFF.

Hearing impression at the time of small volume reproduction was rectified, and the loudness Compensation switch which prepares energy balance is formed.
Two kinds of curves can be chosen according to the characteristic of a regeneration level or a listening room.
The degree of compensation is automatically adjusted with the position of volume control volume.

Three-set (one of them inside of front sub panel) connection is possible for a tape recorder etc., and mutual dubbing is also possible for it.

The balance input and the output circuit are carried.

The surface panel upper part is made into a certain gold tone scratch hair line by the tradition of an Accuphase, and the lower sub panel serves as a black hair line.
Furthermore, the sideboard of the natural persimmon is attached to both sides.
