SoundGirls.Org member and blogger Kerrie Mondy has created this program. Knowing your frequencies is important not only in stopping feedback quickly but also in identifying what may be over-abundant or lacking in your mix.
Train your ear by listening to how the program material is affected when various frequencies are boost and cut.
For best results, listen on your stereo or with a good set of headphones that have ample bass response. Some computer speakers will not reproduce the low frequencies accurately.
