Kevin, your right. VE is the same way-I thought you still had to make the adjustment, though. Anybody know for sure?
I *know* that Avia is set up with the RS meter in mind. No calibration offset adjustments are necessary.
I recall Guy Kuo stating just the opposite.
No. The only compensation is for the discrete LFE in the 6 channel pan. That is 10 dB down electrically.
It would have been undesirable to alter the tones to specfically compensate for a single model of SPL meter. It would have made a mess for any other equipment because that poor sould would have to undo the compensation built into a signal for the RS meter and then applying the correction for the meter being used. Far better to keep it standard and only expose the users to a single layer of compensations.
The signals are kept at electrical equal energy and you should compensate for your particular SPL meter. That means on the RS meter making the SPL reading equal 85 dB to match the 85 dB on the main tests yields a sub which is actually a few dB louder than neutral. Since so many of us HT fans like a lot of LF effects and don't listen at full reference volume, this yields an often more pleasing effect than a fully flat system.
In the last paragraph he touches on what I mentioned above, that the RS meter reads a little low on the LF test tones, so an 85db reading will actually be a few dB high in reality. Not always a bad thing, as he says.
