Here’s a photo of how the FAB2010 XLR Input Module and FAB2110 Input Transformer Module connect to each other.

I added a 2-pin header on the FAB2010 XLR Input Module. Later, I’ll show you how to connect those pins to your switches to control -20dB Pad and switching of Phantom Power.  I’ll also show you how to connect these pins to a Microprocessor, like an Arduino (AVR) and show it’s logic level capabilities.
