Product description:

   This product is all the parts are original authentic, pure unpretentious, quality; the use of high-quality original parts, not only the safety and quality is guaranteed, long life, is more important is to make the actual performance can meet the design goals of a strong guarantee. Pursuit of the best quality is the consistent aim of our restaurant.

product details:

n  with original IRS2092, IRFB23N20D.

n  electrolytic capacitor signal main circuit using ELNA, NXB brand, the main filter capacitor capacity by Japan Chemical 4700UF / 80V * 4, using 25 * 2 (50A) flat bridge rectifier, ensure strong support for a steady stream of power.

n  Resistance selection Rings metal resistance, the main circuit employs a precision of ± 1% metal film resistors rings, ensure the machine a good signal to noise ratio.

N  the PCB using 1.6mm thick double-sided sheet, 2.0 oz copper thickness, HASL whole process to ensure the size of the current through the good performance.PCB-class quality.

n  using 20A high-current inductors shielded, ensuring crisp and powerful sound.

n  particular, to add the current advanced UPC1237 speaker protection circuit, 30A relay control, effectively control the impact of sound power, make your speakers more secure.

n  entire circuit board trace layout are very strict and reasonable, the overall PCB traces using a little grounding. The amplifier board is stable and reliable output power; beautiful mellow sound, open sound field. Dimensional sense of strong, powerful low-frequency sound calm, very good signal to noise ratio, wide dynamic range; details clear, excellent transient response, play a variety of music all rise to the occasion at home playback environment has a very good performance.
