Audio Tip: How to Adjust an Audio Equalizer

It is always better to cut than to boost a frequency control when adjusting an audio equalizer. Boosting a frequency control can add unwanted distortion and cutting or reducing a frequency control can reduce distortion (or at least not add any). Here's an example: Suppose you want to increase the level in the 500Hz range. Rather than boost the 500Hz control, try instead reducing the 250Hz and 1000Hz frequency control, which in effect raises the level in the 500Hz range compared to frequencies above and below it. This technique will work for any frequency, give it a try. Here are more tips for adjusting an equalizer and improving system performance.
