The new electronic fractional frequency power amplifier circuit diagram

Published:2012/12/19 2:25:00 Author:Ecco | Keyword: electronic, fractional frequency, power amplifier

The circuit uses integrated power amplifier driver XG404. It can also achieve good characteristics of the filter divider while making power amplification, so it is a relatively ideal fidelity power amplifier. The rated output power without distortion ( harmonic distortion is less than 5% ) is 24W. The cutoff frequency on bass channel filter is 300Hz, C1 = 2C2 , C2 = 0.16μF, then R = 25KΩ, AU = ( R1 + RF ) / R1 = 100 ( FIG RF = 10KΩ , R1 = 100Ω ), and the cutoff frequency depends primarily on the coupling capacitor.   (View)
