Thank you and have a nice day!Description:This power amplifier board is 268W dual-channel front and rear stage integrated power amplifier board. Uses LM3886 and NE5532, the stereo sound is clearer and stronger.
The input capacitor and the interstage coupling capacitor adopt CBB 2.2UF top capacitor. The main filter capacitor adopts audio dedicated capacitor capacity 210000UF, and adopts 25A and above rectifier flat bridge. ensures a strong and continuous power support.
The uses a five-ring metal , and the main circuit uses a five-ring metal film with an accuracy of 1% to ensure a good signal-to-noise ratio.
PCB uses 1.6mm thick double-sided sheet, 2.0 oz copper thickness, tin full process, to ensure good passing performance of current. First-class PCB quality.
The negative feedback tuning designed by the pre-timing part can reduce the crossover distortion and offer better hearing sense. The volume adjustment is: treble, mid-bass, and total volume.Specification:PCB size: 93x150mm
