Grills, low frequency sound solid and strong, signal to noise ratio is excellent, wide dynamic range detailed, excellent transient response, play a variety of music to cope, playback of the family environment and achieve very good results. This amplifier Board is stable and reliable, high-power output sound beautiful and mellow, sound field open. N Whole circuit board layout is quite strict and reasonable, PCB wiring using ground as a whole. N The integrated "rectifiers, power amplifier, Horn protection for one user to install more convenient" N Resistance selection of rings of metal resistance, main circuit using precision metal film resistors ± 1% ring to ensure good signal to noise ratio of the whole machine. N Front input and Interstage coupling capacitor adopt Siemens top capacitors 2.2UF, electrolytic capacitors signal primary circuit using Taiwan brand names, main filter capacitor by Japan chemical industry capacity 10000UF/50V*4, 25A bridge rectifier flat to ensure strong continuous support. N The original Morocco NE5532 TDA7293 and Texas.
