Trig mic signal too hot, solutions?

Hello, I've bought a set of triggers together with a trigger to midi interface, but it seems that the trigger signal is way to hot for the device, I've got the gain on minimum(15 stages) but it still dual triggers most of the time and false triggering.

Is there any simple way to reduce the signal level with lets say around 75%? I've thought about installing resistors in the signal path, and I don't care about if the sound character changes as they will be used only to trig samples!

Thanks!

make a pad in-between the two. there are many ways to make a pad... do a search for an attenuator/pad calculator
