IRS2092 mono amplifier board (DC power) 350W
product details:
n with original IRS2092, IRFB4227.
n electrolytic capacitor signal main circuit using the brand, the main filter capacitor using capacitance 4700UF / 100V * 2, to ensure a steady flow of power to support strong.
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 The board comes with temperature protection circuit, the general amplifier board is not, the temperature reached 75 degrees automatically turn off the output, better protect the whole amplifier board!
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.
