input values?

[back]

hello.

i want to calculate the values of rc at a jrc 4580.

now i have 20uf for dc blocking in series and 47k input resistance and causes bass roll off at about 50 hz.

i know that if i increase c it will go down but what about R.

if i decrease it roll off will go lower?

how do i calculate?
