recommendation of a sound level meter


I currently have a pair of Quad 988 loudspeakers, Thor Audio TP 60 monoblocks, Thor TP 2000 preamplifier and a
Cary 306/200 CD player. I am attempting to cure the
problem areas in my listening room. At this point I am not really sure what they are. It was recommended that I purchase a sound level meter to help me. Can anyone recommend a sound level meter besides Radio Shack that is
very accurate and reasonably cost effective. Thank you for any light that you can shed.

Are the "corrections" for the RS Meter how much you need to add or susbtract to the meter reading or how far off the meter reading are? For example:

Does "30Hz +3" mean that a 80dB reading is really 83 or 77

Pubul57,

You need to add the corrections at each frequency. So an 80db measured reading at 30hz is really 83db when corrected.

What are the corrections for above 1k (where it gets REALLY inaccurate!)?
Thanks.

The full corrections are published in our instructions for use manual. If you go to our software page and download the instructions for our Test CD, there is a chart that gives the RS values. This was for the older 2050 analog meter. We have done preliminary work with the new 4050 meter and it appears to perform the same.

Rives,
Thanks a bunch! Pp 3-4 should be required reading for all A'goners. I'm surprised a bit that the RS's treble peak is relatively low Q...it's a better mic than I thought.
Thanks again. Ern
