(2012.7.5 latest upgrade, more stable performance)
This product is all genuine original parts, plain, pure quality; the use of high quality original parts, not only the safety and quality to be protected, long life, more important is to make the actual performance to achieve a strong guarantee of design goals. The pursuit of first-class quality is our consistent purpose.
N using original IRS2092, IRFB23N20D.
N electrolytic capacitor signal main circuit using ELNA, NXB brand, the main filter capacitor using the Japanese chemical capacity of 4700UF / 80V * 4, the use of dual rectifier 25 * 2 (50A) rectifier bridge, to ensure a strong stream of dynamic support.
N resistance selection of five-ring metal resistance, the main circuit with ± 1% accuracy of the five-ring metal film resistors to ensure a good signal to noise ratio.
N PCB with 1.6mm thick double-sided plate, 2.0 oz thick copper, tin spray the whole process to ensure the size of the current through the performance of good. First-class PCB quality.
N 20A high current shielded inductor to ensure that the sound crisp and powerful.
The following are the same as the "
The entire board board layout is very rigorous and reasonable, the overall PCB alignment using a little grounding. The power amplifier board work stable and reliable, the output power; sound beautiful round, sound field open. Three-dimensional sense of strong, low-frequency stable solid, signal-to-noise ratio is quite good, wide dynamic range; clear detail, excellent transient response, play a variety of music are comfortable, in the home playback environment has a very good performance.
