Hello,
I have some Whitsle Rock Audio DI PCBs and I'd like to rack them in one enclosure but they need some modifications.
Ideally I'd like them to operate at +22V (or + 24V ) instead of +16V and also I'd like the output impedance to be low enough so as I can plug them into my preamps' mic inputs. So maybe around 100-200Ohms.
(FWIW, almost all my preamps have transformer on the input but I don't think it really matters in this case)
Can you please help me as I'm not quite sure what resistor values need to be changed?
