Does the MQ101 Environmental Equalizer, when added to any system, works like a tone control?Sorry Matt, the answer is yes. Take a look at this article for Tone control circuit. Equalization is done by adjusting tone controls. The MQ101 has 3 tone controls, low, mid, high, and their specifications are listed here. The frequency used for low is lower than that of a typical bass control, and the frequency used for high is higher than that of a typical treble control, but they are still tone controls. Even a 10 band EQ is just a device with 10 tone controls at those specific frequencies.
