An LFE question – I’m confused, again. - 02/01/08 12:44 AM
It has been confirmed that my blue ray player, the Panasonic BD 30 attenuates (lowers) the LFE channel on PCM audio tracks 5 DB’s.
I made the suggestion to users of this machine who happen to use a Denon (or other audio processor) that allows independent channel adjustment to raise their sub 5 DB’s to compensate. That is what I’m doing and it works great. The 3808 allows the user to set PCM multi channel input or analogue input differently than DD or DTS bitstream levels, so when playing a BR disk with the BD 30 and selecting the PCM audio track, it automatically adjusts the channels to whatever level you choose.
So anyway, some other folks responded (AVS) saying that that is not an “accurate” way to compensate and it screws up re directed LFE. I don’t understand what they are saying. Unless the speakers are set to large and the LFE is set to LFE+mains, I fail to see how the speakers set to small would be effected if the crossover is set at or around 80 Hz. Isn’t all the LFE going to the sub below the crossover point anyway? And also from what I’ve read, DD rolls off LFE at 80 Hz.
Am I missing something?
