I´m designing a passive 600 Ohm constant K filter ( High-pass T filter).
I usually use typical balanced line drivers (such as THAT 1646 line driver) and receivers for interfacing my designs with other circuits but I would like this filter to be 100% passive.
So, I would like to use input and output transformers to interface my filter with my audio mixer aux sends. This will be my first transformer based project so my knowledge on this field is quite scarce. Maybe they´re not even necessary?
Checking my mixer specs the Aux send is 150Ohm impedance and the line input is 10KOhm.
So, the transformers main primary/secondary impedance ideal characteristics should be:
Input transformer: 150 Ohm primary - 600 Ohm secondary
Output transformer: 600 Ohm primary - 10 KOhm secondary
I would like to know this is correct and if other important characteristics are needed in order to select an appropiate one for each stage (input and output).
