Behringer 24/96 Auto EQ Continued...

I have used this device with some success for many months now, and unfortunately, what little I learned when initially setting it up seems to already have faded from my memory.

I have made some changes to my room and systems and would like to do another auto EQ, to determine some rough settings which I will then fine tune.

I thought this was simple enough but I am getting a message which says

"NOISE TO AMBIENT RATIO TOO LOW"

This is puzzling as the pink noise sounds very loud to my ears, the room is very quiet,and the Behringer microphone is right in between the speakers which are only about 4 feet apart.

Could someone please advise me and/or walk me through a simple auto eq procedure from scratch?

Thank you.
