WHERE DOES THE ROOM CORRECTION SOUND COMES FROM?. Is this sound produced by the 861, or is the laptop creating the sound.
The room correction noise (and the SPL calibration noise) is gererated by the processor. Mconfig via RS232 is responsible for coordinating the process, instructing the processor and recording the results.
That would mean that the computer card is faulty. But it is strange that all of the rest is working like it should.
I tried everything I could think off and I am going to give up. I guess the only option is to try another computer card. Sinds those cards aren't avalible to me, it is a dead end.
