I forgot to add, to set the level I just matched it to the output of my CD player so that when I change sources between my CD player and TT the volume stayes about the same. If the TT is your only source start out with the lowest gain and if you can't get the desired volume step up the the next higher gain until you can get the listening level you want. It will depend on how much gain the rest of your system has as to how much gain you need from the phono stage.
