PAN 01 : I know little about pretty much everything!

I use this Passive D.I for live vocals at the end of a guitar pedal chain so that when it's going back into the desk the sound man doesn't have to struggle with trying to compensate for the low volume of the mic going through guitar pedals alone and at the same time eliminating unwanted feedback.

Apparently Mic's and guitars have different impedances.

Like I said I don't know much about about anything but I know that paired with a Shure A85F this does exactly what I needed it to do.

Cut's out feedback and helps the sound man mix my live vocals within my performances.

It's a simple design, very light, maybe too light... suspiciously light actually. Could be a problem in the long run getting beaten up by tours but only time will tell.

Can't complain though.. Cheap as chips.
