WebJul 8, 2016 · Problem is, I'm really hearing the crossover notch distortion which makes the headphone out and the internal speakers not very useful for recording purposes. I've tried to bias TR9 as per the schematic: changing R58 to get 1-10mv across R37/R38, but when I remove R58 I still have crossover distortion AND the voltage across R37 is 20mv.

WebJan 24, 2024 · Setup of component crossovers. Passive crossovers are into coaxial speakers, so you do not need to worry about connecting up those crossovers. You … WebThe cross over distortion is the problem that occurs when both the transistors are OFF at the same instant, during the transition period. In order to eliminate this, the condition has to be chosen for more than one half cycle. Hence, the other transistor gets into conduction, before the operating transistor switches to cut off state. WebCrossover Network. Another typical application of filters is the crossover network that couples an audio amplifier to woofer and tweeter speakers, as shown in Figure. (1a). … daily cotton
