i tried asking this question on a computer forum, but no one knew.. i'm using TrueRTA with a berhminger ECM8000 mic, rolls phantom power and the creative soundblaster audigy 2 zs for notebooks. i tried it out and it looked okey, but i forgot that the rolls puts out a balanced signal. i can't find any information on whether the soundblaster can use a balanced single, if it affects the measurements, ect. thanks :)
