3 wayTL074 is an active filter 3 lines built by . In a 3 way point is able to pass 3 band tone (Bass, Midrange, and Treble) separately. Active is constructed of active filter Low Pass, Band Pass and High Pass are made with Op Amp TL074 that has slewrate very low and low noise. Working voltage for the of this active is a DC voltage symmetrical ± 15 volts.
Circuit Of 3 Way Active Crossover TL074
Working frequency of the activeLow Pass is a pass for bass tone frequencies below 300Hz are formulated with the following formula.
fh = 1 / (2 * π * R1 * C1)
For High pass filter of the above active crossover circuit is ansignal pass treble tone with a frequency range above 3000Hz, and formulated with the following formula.
fl = 1 / (2 * π * R3 * C3)
Then for the band pass filter for passing intermediate or midrange tone is the tone missed over the frequency range below 300Hz and 3000Hz frequency range.
