1000W HIFI High Power IRS2092+IRFB4227 Class D Mono Digital power amplifier board
Product Details:
The latest production HIFI mono high-power IRS2092 digital amplifier board, can cope with 2 ohm load, this can not say that there is only, but also extremely rare. The effect does not have to doubt, the sound freely, low-frequency flexible, dynamic first-class.
Power amplifier board comes with temperature protection, speaker protection, midpoint DC protection, can bridge. Effective power 2 ohm 1000W, 4 ohm 900W, 8 ohm 600W. Stage 8 ohm can be bridged with two power amplifier boards to achieve 2000W power output.4 ohm is not suitable for bridging.
The main chip uses the original IRS2092 and MOSFET IRFP4227.
