Today's project brought to you by the budget musician. XLR attenuators/pads.

Unscrew and remove the female side of the adapter and unsolder leads.

Solder R1 and R3 on xlr pin 2 and 3

Reconnect leads to R1 and R3 of their previous pins.

Shove everything back into the barrel, replace screw, test it out and your done.

*bonus the DIY T-pad circuit is calculated to the actual input impedance of your specific preamp unlike store bought versions meaning amount of attenuation is more precise.
