Re: First equalization and having trouble.. anyone help please


With REW SPL meter cal file loaded...

Band limited pink noise for the subwoofer in DVE = 75dB (RS digital meter at 80 C weighting) in REW or 67dB C weighting on a RS digital meter set to 70.

Pink noise at -30Db FS in REW = 75dB on a (RS digital meter at 80 C weighting) in REW and 67dB on the RS digital meter set to 70.

Band limited pink noise for other channels in DVE = 67dB (RS digital meter at 80 C weighting) in REW or 60dB on a RS digital Meter set to 60.

Pink Noise in REW at -20dB FS = 85 in REW or 77dB on RS digital SPL meter at the same setting

Therefore in DVE my subwoofer should measure at 67dB on my RS SPL meter at 70 and should measure 75dB in REW at 80. My mains should measure at 67dB on my RS SPL meter (set to 70 C weighting) and 75dB in REW set to 80. No 3dB difference that I see going on.

I setup my mains and subwoofer using the limited bandwidth pink noise similar in REW and my full bandwidth pink noise pan around the room is at like 77dB. My mains ended up at -8 when set to small for the DVD side. It wants me to raise the volume on an AVR.

I wonder why is there no Full bandwidth Pink Noise in REW and what is it on DVE for. I also am curious hy is it louder. Could be something to do with a dial norm on an AVR maybe.
