Hi Everyone,
I am making a front panel for a mixer and I need to know where to put the dB hash marks. I have a fader and an ohmmeter but I don't have a easily accessible audio circuit, nor do I have an accurate dB meter on hand.
How do I calculate the resistance corresponding to each 5 dB of drop, assuming that the top of the fader is zero dB drop and the bottom is infinite drop?
Can I just use this formula, normally used to calculate volts from dB and instead use it to calculate percentage of fader resistance, assuming the top of the faders is 1 volt or 100%?
V = Vref * 10 ** (dB/20)
Where Vref is 1, V represents my percentage, and dB is -5, -10, etc?
Thanks.
