Tone controls
In another thread which google ½ FUBARed, tone controls were
mentioned. Pots are the best way to control audio. Now I never built this circuit but let me splain it. I want opinions, and number one is audio quality. cost does not matter. I wanted a bass control with extreme range and a continuously variable turnover. Rather than playing around with the geometry of the components I simply amplified the signal about 20dB, and resistively divided it back down, and sent it throught a low output impedance buffer. Put the R/C network at the slider and a rheostat determined the crossover frequency. At the time I figured getting tightly matched stereo pots was hard enough, I didn't need to complicate it. The specs boiled down (it took a while to do the math) to +-18dB from 0Hz to a variable crossover of 44 to 484 Hz. I know idiots blow speakers if you give them a control like that, but I would still like to build one just for the hell of it. Can you still buy pots ? I'll take just about any resistance and build around it at this point. Actually my system is so flat from about 30-16,000 or so, I only want those extreme ends boosted, nothing else. Even a 12 band EQ will not do that. Can potentiometers still be had ? especially the audio taper ones ? The design is like a mixing filter and should suffer alot less phase problems. But can I get the pots ? JURB |
