Where should this "0dB" setting be on the receiver? I only have a calibration menu that pops up for setting the speakers and sub; my sub is set to "+6" on this menu, plus the LFE low pass rolloff is set to 100Hz...

It's in the different menu. I have top of the line Integra, so yours maybe have different pages. It has nothing to do with the one you mentioned.

So, when playing uncompressed tracks, "MULTICH" is correct on the display? Should I be using DIRECT mode here rather than MULTICHANNEL or not?

Direct will disable bass management, so don't use it.
Multich is for PCM yes use that.

If the LFE is not dropping by 10dB, then why is there such a reduced impact of bass when playing these PCM tracks? I do not experience this with bitstreamed Dolby and DTS signals...

You have to look for that LFE setting I told you about, and make sure it is set for the highest setting which is 0db.

if I lose bass by keeping any setting on PCM, then perhaps this is WHY the uncompressed PCM tracks are losing bass as well?

Nope, the only reason you would have that problem if the player is downmixing those to 2 ch PCM, in that case you loose the entire LFE. With DTS HD MA the player very likely convert the core DTS to 2 ch PCM since it cannot decode hence recover the entire data stream. DTS HD MA is nothing more then a losslessly compressed PCM data, so when you unable to recover all that's needed, data will be lost, in this case entire channles, unless you transmit the lossy core in bitstream. get it?

Panasonic '10A player which DOES NOT HAVE HDMI 1.3 CAPABILITY and therefore DOES NOT SEND THE NEW SURROUND CODECS VIA BITSTREAM? So, the only way I can listen to a Dolby TrueHD track is to set it to PCM -- but, if doing this is creating a two channel downmix, which loses LFE, should I be doing this at all?

Yes I was aware, that is why there is a difference between the True HD decoding which the player can do, so no downmixing is invilved like for the DTS HD MA track.

No, but the "last valid" settings in my listening mode setup for default modes are not engaged for MULTI CHANNEL -- in other words, under "MULTICHANNEL PCM" for listening mode presets on the receiver's setup menu, I keep this on MULTICHANNEL all the time -- NOT Last Valid, so I am wondering WHY the receiver displays MULTI CHANNEL as the listening mode for uncompressed PCM tracks or PCM'ed Dolby TrueHD signals...follow?

Because you had selected it, as you just said it.

The manual says if you are connected to equipment that CAN decode formats, do calibration settings, etc., that the speaker settings at the player should be set to 2-CHANNEL here...if you are connected to equipment that CANNOT do level settings (which of course I am not), then select MULTI CHANNEL here....listening to this, you would think, because I AM connected to an Onkyo receiver doing the levels and distances and such, that I should leave the Panasonic setting on 2-CHANNEL....but this doesn't seem to process the audio tracks right with PCM...what is going on here?

Just ignore that, Use the multich setting.
