parameterOutput power: 125-250WRated voltage: 220VDesign L15D-PRO Digital D-Class Power Amplifier by LJMAll LJM products are accurately measured using AudioPrecision 2 from the United StatesBased on the original factory design of IRAUDAMP7 IR company.Adopting the original imported main chip IRS2092S. And IR company’s digital audio dedicated MOSFET field-effect transistor IRFI4019.IRFI4019 is a Class D audio specific MOSFET produced by IR company. There is a significant difference from many industrial MOSFETs used online.It has low distortion. It is the best match for the same high-quality sound as the original IRAUDAMP7.Power amplifier parameters:Using voltage DC:+-35V to+-50VPower: 150W 8R THD<0.05%300W 4R THD<0.06%Area 147 * 60 MM long and wide.The power amplifier board comes with a DC output cut-off protection. Short circuit output protection.Overload protection. Equipped with thickened and raised heat sink for sufficient power. Can achieve a rated output power of 300W 4R.With the latest developments in semiconductor devices and circuit technology, Class D audio amplifiers are widely used in television/home entertainment, audio equipment, and high-performance portable audio applications. High efficiency, low distortion, and excellent audio performance are key driving factors for the widespread application of Class D amplifiers in these emerging high-power applications. However, if the MOSFET in the output power bridge circuit is not selected properly, the above performance of Class D amplifiers will be greatly compromised, especially when the output power is relatively high. Therefore, in order to design a Class D amplifier with the best performance, it is crucial for the designer to correctly understand the key parameters of the device driving the speaker and how they affect the performance of the audio amplifier.IR Company designates a digital amplifier specific field-effect transistor IRFI4019:VDS=150VPD=80W
