Generally, three-stage active Equalizer filters require three control bass, treble, and MID. Today, modern amplifiers tend to rely increasingly on digital signal processors (DSPs) to produce the bass and tone; consequently, the preamplifier and input signal switching is usually within the same DSP IC. The signal amplitude at the output, may be as much high as 20Vp/p. Output of 9 volt peak to Peak can be achieved. TL081 contains only a single operational amplifier, and it matches TL071 and LF351. Which low quality than Active tone control. However, what would happen if this DSP stopped working or the microcontroller that controls it failed and there was no way to replace it. Bass, Mid and Treble. If you have an audio preamplifier whose "tone control" does not fully satisfy you, you may replace the existing stage with this stylish 3-way stereo tone control circuit which can act not only on treble and bass, but also on mid tones. Jul 13, 2018 - Bass Treble Tone Control Circuit Bass and treble circuits can be combined to form a two control tone adjust circuit, as shown here.
