[Testpattern]

Sure...

I utilized a Rives Audio CD-2 test disc which covers the audio spectrum in "1/3" octave steps (not 1/6 as previously reported).

I performed this comparison over a range of 20-400 hz. Meters were measured in my listening room mounted in a fixed location (sweet spot). Two sets of curves were collected manually for each meter by noting the meter deflection at each test tone. Readings were virtually identical between the two readings for each RS meter. When the two passes for the 42-3019 were completed, it was removed from the fixture and replaced with the 33-2050 and the same sweeps repeated twice more. The average for the two 42-3019 sweeps were compared to the average for the 33-2050 sweeps. The differences were minimal with any observed varances less than 1 dba.

Although the older meter seems to reflect the same values as the newer model, it isn't as useful overall. The 42-3019 minimum scale is 70 dba where as the new 33-2050 includes a 60 dba selection in addition.

I hope this is useful.
