Accurate high pass and low pass filters reduce low frequency rumble and high frequency hiss. Selectable slopes of 6, 12, 18, 24, 30 and 36 dB/Oct and frequency control range covering the entire audible spectrum make the NF575 filters extremely flexible.
Advanced notch filters allow the user to select the amount of signal cut, cut frequency, and width (Q). All five NF575 notch filters can be linked harmonically to address common cyclical noise problems such as 60 Hz hum.
