I am making a 5 band graphic equaliser project. For that I'll be using 5 second order band pass active filters using opamps,1 power amplifier,1 summer and a preamplifier. I have divided the audible frequency range into 5 centre frequencis viz-50Hz,250Hz,1kHz,4kHz,16kHz. Now the problem I don't know the "boost" and the "cut" level that should be applied? Is there any standard levels for that?(I read at most places as 12dB)
