But were not even in that stage yet.
Yeah, I realize that, and you're correct. I was only responding to your statement that you would have to purchase new connectors. I meant that in the end, there is no getting around it. The meter is unbalanced, so you'll eventually require the unbalanced hookup.

The problem is now that the soundcard is measured to low. The spl meter isn't connected yet, only line in with line out. Or has it anything to do with the soundcard being unbalanced?.
Yeah, the soundcard cal is definitely the first problem at hand, and that can be accomplished with a balanced (or unbalanced) conection between line-out and line-in of one channel.

Are you able to make that connection and select it in REW. In other words, is the channel one selected when you select LEFT in REW or RIGHT. Try both.

I wonder why this isn't mentioned in the REW guide that you need a ST 1/4 jack if it's so importent.
Because 99.9 % of soundcards simply use a 1/8" unbalanced connector which supports left and right channel. Your breakout box is unusual.
