While we are on the subject - what is the relationship of potentiometer resistance to volume output?
Are attenuators linear or logarithmic?
If you have an attenuator that scales in .5 db increments from -72db to -0db is it linear or logarithic?
Is -36db half the attenuation as -0db? At -36db on the scale are you killing half the power available? On a single frequency test tone would -36db on the scale be half the SPL of -0db?
Can't be that simple.
