Ghani Lawal- Sub-Bass filter produces a 2V 343Hz output even when there is no signal input, that is why the LEDs are always activated
- The Midrange filter only lights up a few of the blue LEDS for the same voltage that lights up all 10 LEDs for the other filters, that means it is attenuating the signal by at least 18dB, or at least 85%
