A-203MK Signature pure class A amplifier is on behalf of my company's transistor amplifier development and design experience and manufacturing capacity of the comprehensive performance. Using a large number of international audio products manufacturers and enthusiasts agree with the full balance amplifier circuit, so that sound quality, sound, sound field, drive capacity to achieve the culmination of the degree of performance.
A-203MK Signature is the original A-203MK standard version based on the upgrade products, mainly inside and outside the audio-specific devices for the Hi-END-class wire, terminals and electronic components.
The core of the preamplifier is the high-speed DC amplifier module developed for years of experience, IC and discrete components of the sound quality performance. Volume control using the United States CRYSTAL company's electronic volume control chip CS3310, so that the error between the channel level control within 0.5dB, much better than quadruple mechanical potentiometer ± 3dB control accuracy.
The whole transformer is filled with epoxy resin, effectively reducing the vibration noise generated by the transformer work, each channel power filter capacitor is used in Japan ELNA audio electrolysis, the total Capacity up to 120,000 microfarads, 32 high-power transistors composed of 100W class A output level, in addition to the performance of the delicate sound thick also pull the mountains and rivers of the potential.
In line with the performance of the machine to the extreme, the use of the German WIMA brand MKP 10 specifications and M-CAP licensing special film electrodeless capacitor, colored ring high-precision metal film resistors, parallel precision power supply. The post-stage signal input circuit consists of a Toshiba field-effect transistor consisting of a cascode differential amplification, and a Toshiba transistor for a second-stage differential voltage amplification and current drive. The speaker connection terminal uses eight German-made WBT brands, and the wire connected to the terminal uses the US LITON brand copper-plated silver speaker line. Transformer power input line to use the United States XLO power cord, with the fuse connected to Germany Vincent brand audio dedicated fuse. DC low-voltage power supply line also switch to the United States KIMBER audio dedicated wire. DC power supply filter capacitor upgrade to Japan NICHICON brand MUSE specifications. Signal channel circuit selection of the United States DALE resistance to significantly improve the sound quality performance.
A-203MK Signature introduced the CPU full-function control and data information screen display, so that advanced HIFI amplifier into the epoch-making digital technology, in order to make fans more convenient to use the machine, set up an infrared full-function remote control system, The control of the whole data exchange effect.
A-203MK Signature amplifier design to reflect the main purpose of product content, abandoned the high-power amplifier monotonous rugged style, to take the overall shape and detail of the interaction of the way, so that it has a symbol of the power after the class There are pre-class control charm, to solve the high-power merger machine modeling post-dull problem. The top cover is also changed from the original silk screen to engraved aluminum text, has been shown with the original standard board distinction. In today's world of silver machine boldly using black, and a small amount of aluminum metal parts decorated them, which not only enhanced the visual impact, but also made the black unprecedented charm, steady atmosphere, the overall relationship with the interpretation of the details Very exciting, wonderful, very patient.
