accu8 crossover Low pass, The low pass crossover is 24 dB / oct. Setting it at 80 Hz will have the signal attenuated with 24 dB at 40 Hz (1 octave). To ensure accuracy for the individual crossover frequency the pot feature 41 clicks, each with a corresponding frequency. The same is valid for the bass boost settings, which also features 41 clicks.
