C-200
Description
Utilization of direct-coupled, push-pull drivers in all stages of the Accuphase C-200 has vastly improved the characteristics preceding negative feedback application. This has resulted in an equalizer circuit with outstanding fidelity and stability.

Employment of complementary - symmetry, Class A amplifiers in the last stage of the equalizer circuit which utilize rugged power transistors and are fed by symmetrical dual (positive and negative) power supply systems ensures wide range input handling capability up to 400mV rms at 1 kHz with less than 0.05% distortion.

The C-200 stereo control amplifier is equipped with a disc low enhance switch which accentuates rich bass tones that add to music enjoyment. This switch offers 0, +0.5 and +1 dB change against the RIAA characteristic curve at 100 Hz.

Output voltage of cartridges vary depending upon the manufacturer. Disc level controls are provided to unify the levels of Disc 1 and Disc 2 quickly and easily. Disc 1 has provisions for impedance matching to transformer-coupled moving coil type cartridges. This is achieved with a 3-point impedance matching switch which provides impedance selection of 47, 30 or 20 K ohms.

Turntable motor and tone arm resonance vibrations outside the audible range can still mar sound reproduction by causing intermodulation distortion in the hearing range. The C-200 stereo control amplifier is equipped with a subsonic filter which eliminates such low frequency vibrations below 25 Hz.

A directly coupled, special amplifier for exclusive headphone use is provided to ensure highest fidelity for private listening through stereophones.

Regardless of the signals handled, the power supply delivers constantly regulated, non-fluctuating voltages. Even against normal AC line voltage fluctuations, this power supply is capable of delivering very stable DC output voltages.

Bass and treble tone controls, both provided with 10-step selection, plus a further choice of two turnover frequencies for both, permit selection of practically any tone variation. This switch permits instantaneous comparison of any tone adjustment against a truly flat response characteristic.

The C-200 has a total of 10 inputs and 7 outputs terminal systems which make it easily adaptable to a wide variety of program sources in almost any conceivable type of installation.

A total of three tape recorders can be connected simultaneously. Copying from one tape recorder to another is possible even while listening simultaneously to another program source. This is achieved by a separate tape copying switch that is independent of the tape monitor switch.
