Features
1; current output stage using a pair of IRFP240 / IRFP9240 mosfet transistor, the output impedance is low, Deliver surficient output power, closer to the ideal amplifier.
2: Carry a perfect midpoint voltage protection circuit, speaker delay protection circuit, the main chip using the Japanese production UPC1237, the integrated circuit is stable and reliable.
3; using a DC servo circuit, coupled with a reasonable PCB layout, making the amplifier midpoint output is less than 5MV.
4: double-sided 2mm glass board PCB design, 1% precision metal film resistors, the United States mica capacitors, Germany Weimar capacitors, imported audio dedicated high voltage electrolytic capacitors, all components to ensure that the new original import, put an end to second-hand goods.
5: LME49830 power amplifier board for the mono design, the composition of the two-channel need two of the power amplifier board, each channel using a LME49810 + a pair of FET design, left and right channel PCB symmetrical structure.
