IRS2092 Class D Audio Amplifier Board Dual Rectifier with Protective Power IRS2092 IRFB23N15D
Overview
The 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 , solid and powerful low-frequency steady , very good signal to noise ratio , wide dynamic range ; details clear, excellent transient response , playing all kinds of music are comfortable with , in the home playback environment has a very good performance.
Features
- Using original IRS2092, IRFB23N15D.
- Signal main circuit electrolytic capacitor using ELNA, NXB brand, the main filter capacitor using the Japanese chemical capacity 4700UF / 80V * 4, using 25 * 2 (50A) flat bridge rectifier , ensure strong support for a steady stream of power
- Resistor selection of rings metal resistance , the main circuit employs a precision of ± 1% metal film resistors rings , ensure the machine a good signal to noise ratio .
- 1.6mm thick sheet using double-sided PCB , 2.0 oz copper thickness , HASL whole process to ensure that the size of the current through the good performance . PCB -class quality .
- Using 20A high current shielded inductors , to ensure crisp and powerful sound .
- Special add current advanced UPC1237 speaker protection circuit , 30A relay control , effective control of the boot impact sound , make your speakers more secure.
