I have a regular dynamic microphone (e.g. Shure SM57) and a regular power mixer with a PA system. When I connect my microphone to the mixer with a regular XLR-XLR cable I get a satisfactory volume at 25% value of that channel volume (assuming I have some master volume on).
Now, I want to use the jack input instead of the XLR input on the mixer. The reason is that at some later stage I would like to use an effect pedal (which only takes jack input). I am using Audix t50k to convert signal from XLR to the jack input. Thus I have microphone -> XLR-XLR cable -> Audix t50k -> jack input on the mixer. And in this case I have to put the volume to 75% value of that channel volume to get the satisfactory volume as before.
As far as I understand, this is an expected behavior. What do I have to do to still use 25% of that channel volume while using impedance matching transformer?
