Description
The Accuphase E-202 is a Integrated Stereo Amplifier which possesses a great many separate component class features and characteristics.

Full play has been given in its design to the advanced engineering techniques that were developed far the P-300 Power Amplifier and the C-200 Control Center which spearheaded the Accuphase line of highest quality audio equipment.

Among the many special features of the E-202 is the high power output of 100 watts per channel into 8 ohms assuring excellent sound quality at ALL listening levels.

This high power capability, with distortion at less than 0.1% over the entire audio range of 20 to 20000 Hz is fully guaranteed.

Heavy duty power transistors in a parallel push-pull drive output stage and large heat sinks back up this Accuphase Warranty.

Design emphasis was placed on maintaining excellent sound quality also at the low listening levels.

P-300
Description
It is a mistake to calculate the value of a power amplifier solely in terms of $/power or cost/power.

Other more important factors should also be considered to assess its overall value such as those power qualities like low distortion, well-regulated power supply and power bandwidth, as well as additional functions and appearance values.

Music delivered through a good power amplifier should have an extra quality of deep, rich bass and the subtle nuances of inner musical fabric which stir and warm the soul with emotion.

A good power amplifier must also have the range to reproduce precisely the softest to the loudest passages of music, and, at the same time, it must be able to handle, without distorting, all the large input amplitudes that may be involved.

The P-300 can coast through all of these requirements without strain due to its large, heavy-duty power transformer and 2 x 40,000 microfarad filter capacitors, its all-stage, push-pull circuit configuration, and well selected and thoroughly tested parts.

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.
