Hi,
It was suggested to me by one of my sources that the DSP EPROM update in the latest RSP-1098 firmware release (plus the native EPROM code in the RSP-1068 and RSX-1067) fixed the issue that many of us RSP-1098 owners had with the Sub level in the Test Tone menu being 10 dB too low - resulting in us needed to either calibrate the sub at 85 db relative to the 75 dB for the other speakers OR use a DVD Set-up disk to set the sub level.
The problem as I am given to understand it - was that the sub test tone level was set at 30 dB below reference - as for the other test tones. It's just that reference for speakers is 105 dB (hence 75 db) while reference for the .1 LFE channel is 115 db - hence the old sub test tone should have given 85 db, making it 10 dB too soft when calibrated to 75 db. The sub test one is now set at a level of 40 db below the 115 db reference, making the 75 db calibration accurate (I hope that’s clear....)
Well - today I tried and (for me at least) it's fixed. The RSP-1098's test tone for the sub calibrates at the same relative level as the speakers.
Can some others who have done the upgrade please check to see if we have a consistent fix?
If (as I suspect and Rotel hopes) we are all fixed, then it's a good thing to remember for those using the "set the sub tone at 85 db" fix we had before - this will give WAY too loud bass now
Will also help prevent some (understandably) excited new RSP-1098 owners reading all those old posts to learn what to do right and calibrating their subs wrongly given the fix...
Enjoy
Geoff
