The new improved external output terminal;
A set of audio signal input terminals (LINE 5) are used to connect the other preamplifier audio output terminals so that the unit can be used as a stereo
A-203GS Class A amplifier is representative of my company over the years on the transistor amplifier development design experience and manufacturing capabilities of the integrated 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 performance reached its peak level.
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 American Crystal Corporation manufactured 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, , 32 high-power transistor composed of 100W A class output level, in addition to delicate performance in addition to the delicate thickness of the potential pull the mountains and rivers of the potential.
In line with the performance of the machine to the extreme, the use of MKP audio special film electrodeless capacitors, 1% high precision metal film resistors, parallel precision voltage regulator. The post-stage signal input circuit consists of a field-effect transistor consisting of a cascode differential amplifier, a famous transistor for a second-stage differential voltage amplification and current drive.
A-203GS introduced the CPU full-function control and data information screen display, so that advanced HIFI amplifier into the epoch-making digital technology field, in order to make fans more convenient to use the machine, set up an infrared full-function remote control system, The Manipulation Effect of Human - Computer Dialogue with Full Data Communication.
A-203GS amplifier design to reflect the main purpose of product connotation, abandoned the American high-power amplifier monotonous rugged style, to take the overall shape and details 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. Details of the rich and elegant, every detail is from inside to outside, derived from large to small, natural wonderful and no artificial. In today's world of silver machine bold use of black, and a small amount of aluminum metal character decorated them, which not only enhanced the visual impact, so that the black had an unprecedented charm, steady domineering, the overall relationship with the interpretation of the details Very exciting, wonderful, very patient, temperament in the show eternal.
