Hi,
I would like to add a three stages pad (with 0 / -20 / -40 db attenuation) to the mic channel input.
I'm thinking to add this (right side) pad design to the input of my 602:
How can I calculate the values of the four resistors of this pad circuit so it will work fine with the mic input transformer (it's a Beyer TR BV 351 015 006 / 1:15 ratio / 200 Ohms)
Here's the pad circuit connected to the mic input transformer:
