For people who are building/racking mic preamps and want to add a line input to them here is a simple way.
This provides you with a input that any modern or vintage line level device can be comfortable driving, cuts the level -50dB and provides a source output that looks like a microphone signal to your preamp. Use a non-shorting (BBM) switch, so any phantom power you have on your mic input connector will never reach your line input connector.
You can also use this resistor network with XLR barrel connectors to make pads that you can take for use with any mic preamp for tracking or mixing. Any time you want to put some preamp love on line level signal that could benefit from it.
Enjoy,
Joel
