First measurement issues...

[RdW]

Good evening,

I am a new user of REW and try to understand what goes wrong with my first measurements. I have attached the file where this is explained. Does somebody recognise the drop in dB at approximately 6/7 Khz?

Thank you!

Never mind, found it already
The MiniDSP was not on a mic-stand.
Case solved.
Cheers

Unfortunately, the issue came back and I have no idea why.

Can you please help me to understand what happened?

Thank you!!

My Guess ( since I don't have WiFi in my playback chain ) is that the delay caused by running your audio through your WiFi is causing REW to only pickup//analyze a portion of the test signal.

You can checkout this theory by connecting your computer ( that's running REW ) directly into your PreAmp//Amp setup and trying again .

Use the acoustic timing reference to synchronise the capture and deal with any playback delays.
