8.2.3 Baxandall Tone Control

Figure 8-9 gives an example of ultra-low noise and THD tone control. This circuit provides 20 dB of gain at the first stage, followed by two separate tone controls for bass and treble. The passive circuit is designed to yield a flat gain response with the potentiometers both set to 50%.
