recommendation of a sound level meter

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

Rives, thanks -- nice site by the way. I had two or three different adjustment factors for the RS meter. Your correction factors line up exactly with those Sean posted a few years ago. Now I finally know which to use. Now if I could only get my system down to 10 Hz ;-)

Rives, if my understanding is correct, your CD is made for stock RS meter. Does it mean that it's not usable in case I'm using an external mike?

Dmitrydr: I'm not sure if I know the answer to your question as we have not tested an external mic. However, I can tell you this much:
1. The majority of the correction is for the C weighted circuitry. The remaining is for the fact that this C weighted circuitry is not quite right.
2. The external output of the RS meter is not weighted in any way and is just about flat up to around 2k. Above that the response is somewhat iradict and a better mic input would likely improve the response.
Hope that helps.
