Re: Noobie with REW help with measurements


I still have the issue with the levels.

When I set the level to 75 dB on the meter, and then go down to start the measurement, REW tells me the input level is not high enough. Then I would turn the volume up on my pre until REW told me the level was good for the measurement. I would then take the measurement, and run the set target levels button... I would do this for each speaker, this is why the target level is different for each one. I believe the cause of this is proximity, the meter is set up near the back of the room at what will be my seat. The sunfire happens to be right behind the chair, but the HSU and the mains are in the front of the room (~ 17' away). I can get the SPL to read 75, but then the input level into REW is around -30dB, and REW tells me I need a higher level to get an accurate reading...

My hope with the extra sub is so that I can minimize modes for more listening positions. There are 8 seats in the room, and instead of 1 sweet spot, I am hoping I can get pretty good response in a majority of the seats... If this becomes impossible, then I will have to lose the little sunfire.

EDIT: I should also say that my meter is the rather old radio shack analog meter...
