Hello, today finally my measuring microphone of Audio System came. I immediately got into the car with it and a laptop. I then set everything up and connected as it is described in the magazines of “AutoHifi”. So, now I wanted to make the first measurement. I also ran the pink noise and always led the microphone from one ear to the other. Now comes my problem. In the instruction is that you can quietly read the system properly. This is not possible with me, however, as soon as I turn the volume higher than 6 (quickly quiet), a red light bar appears immediately in the program practice where “**REDUCE INPUT!** ” stands. What is this, perhaps on the laptop? Is already a little older and has only 1000Mhz. I first connected the Mirko to the small amplifier which was there and then went from there into the microphone input from the laptop. Unfortunately the laptop does not have an extra line-in. of course I also connected to the cigarette lighter as it says in the instructions. Would be nice if you could help there, so that I might be able to measure correctly tomorrow. MfG, Dirk
