Balanced Line to Mic Pad DIY??

Zero Cool · 21st February 2006, 10:43 PM

Can anyone tell me how to make a quick and easy Line to Mic level pad that wont load down the mic line?

I have a plate with 2 XLR jacks on it, one needs to be Line Level input, the other Mic level input. however i only have a mic level input to connect to. I need to build a passive pad on the back of the plate.

Only one of the jacks or the other will be used at any one time so i need a way to drop the line level down to mic level, yet at the same time, if they choose to use the mic input, the passive pad wont load the mic line down too much to be unusable.

Any ideas????
