About the item Accuphase C-200X ¥270,000 (released in June 1980)/¥280,000 (revised in January 1983) Based on the C-200 and C-200S, the C-200X is a stereo control amplifier that has been greatly improved by introducing the latest technology. Based on a full amplification stage push-pull system, it employs a cascode bootstrap push-pull differential input system. The cascode bootstrap provides large gain and improved high-frequency characteristics, At the same time, it also improves the distortion rate by increasing the input impedance. This circuit is used in the equalizer amplifier and the high-level tone control amplifier. The equalizer amp and high-level tone control amp use the DC servo system and are completely directly connected from the MM disc input to the output. The DC servo amplifier uses an IC, and the output of the IC does not directly control the signal system of the differential input amplifier, The output of the IC is not directly controlled by the signal system of the differential input amplifier, but by controlling the base current of the constant current source. This servo circuit minimizes the influence of noise from the servo system on the signal system and has excellent DC drift control capability. Therefore, it can be used in an equalizer amplifier with high low-frequency gain to achieve excellent results. The head amplifier section consists of differential push-pull inputs and RET pure-complementary output circuits. The input section, which affects sound quality, is directly connected without using capacitors. Independent constant voltage power supplies with RET and ICs are placed at a total of six locations for the head amp, equalizer amp, and high-level amp (left and right). The head amp, equalizer amp, and high-level amp are each equipped with a multiple power supply system. These are located in close proximity to each other in the circuit and maintain a low impedance over a wide bandwidth, This reduces interference between the units. The headphone amplifier section uses a pure DC Class-A complementary direct-coupled dedicated amplifier. A printed circuit motherboard system is used for the connection between the unit amplifiers, the power supply and some functions. The glass epoxy motherboard contains sockets to plug in each unit amplifier, a power transformer, rectifier, filter capacitors, and a front panel push switch, The front panel push-switches are mounted on the motherboard. Each part is connected by printed circuit conductor paths, eliminating variations in characteristics caused by uneven routing, which tends to occur with wire wiring, and ensuring uniform performance, This eliminates variations in characteristics caused by uneven routing, which is often the case with wire wiring, and ensures uniform performance. The tone control section employs a 2dB step system with independent left/right 11-contact rotary switches, which has been used since the C-200. A turnover switch is also provided, and an ON-OFF switch is also provided to deactivate the tone control. A loudness compensator is provided to correct the audibility and energy balance during low volume playback. Two different curves can be selected according to the playback level and listening room characteristics. Subsonic filter and high filter are provided. -20dB attenuator switch, mode switch with 5-contact rotary switch, and disc input impedance switching switch, output ON-OFF switch, and other functions.
