That is how it should be. When you send discrete 5.1 channel PCM to the receiver, it simply cannot apply any of the DSP modes since they meant for 2 ch analog or PCM. So the receiver behaves as it should no mistery here. Use the multi channel mode!

Yes, I UNDERSTAND this, but what my issue is, is WHY does the manual say to select MULTI CHANNEL if you want the PLAYER to handle all speaker settings, etc. and use 2 CHANNEL if you're connected to a receiver which can do this? I AM CONNECTED TO A RECEIVER THAT CAN DO THIS, but I am also connected DIGITALLY via HDMI, so I don't get what's happening. If the MULTI CHANNEL settings on the PLAYER are FOR CONTROLLING ANALOG AUDIO OUTPUT ONLY, why does it affect what I have connected via HDMI???

So, I SHOULD NOT use the Pro Logic II, etc. modes for playing back the PCM tracks (of course, by leaving the player on "2-CHANNEL")? Why does the "MULTI CHANNEL" playback mode work better for these uncompressed, etc. tracks?

Just checked the manual for the 605, it lacks the LFE pad that is available on higher end Onkyo models. Sorry.

Okay, well in that case, I have an "LPF of LFE" selection under the SPEAKER CONFIGURATION menu, which asks you to set the subwoofer's low pass filter; the selections here are for 80Hz, 100Hz and 120Hz...I have it on 100 now, but my other speakers are all set to roll off at 80Hz because they're bookshelves and I would like the sub to handle the bass below this mark. What should the low pass filter be set on here? 80, 100 or 120Hz? I am running a 10" powered Polk sub.

This player CANNOT decode this track period, it only extracts the core, which can be transmitted via HDMI or SPDIF[optical, coaxial] and it's bit rate is 1509kbps for 5.1 channels. It roughly equals to a CD which is about 1.5mbps at 44'khz sampling rate. For discrete multi channel PCM you would need 3x as much more data info. So when you have the "multich" appear on the Onk while you send DTS as PCM and see how many channel indicator is lit on the front panel which indicates how many channel the receiver gets.

I lost you here....I KNOW the player cannot decode ANY MASTER AUDIO at all, yes, I know...so, when playing these tracks, I usually set the "DTS-HD" audio output of the player to BITSTREAM, so the CORE DTS mix is being passed to my receiver bitstream, where it displays "DTS" on the front panel....is this correct? EITHER WAY, am I getting JUST the CORE DTS mix if I bitstream or PCM it with Master Audio tracks?

I was informed recently on another site, which confused me beyond belief now, that by keeping the DTS HD audio output of the player set to PCM when playing Master Audio tracks, this is better because the actual HIGH DEFINITION portion of the MA stream is being sent (in other words, the player says "DTS HD MULTI" on its onscreen display when playing Master Audio tracks, perhaps suggesting that the "HD CORE" of the DTS mix is being sent INSTEAD of just the "REGULAR DTS CORE"....is this what is happening, or is the receiver seeing the core DTS mix either way, bitstream or PCM?)

BD players have secondary audio decoders built in,mandated by some of the interactive options like PIP commentaries and such, and that requires that the player mix all those togheter and then send it out as you choose them. Because of this and the fact that this player can't bitstream those HBR tracks [DTHD, DTS HD, etc] the DSP engine that responsible for tasks like bass management will be in the loop at all times, hence why bot the 2ch and MCH setting will affect the HDMI output.

THIS is something that probably should have been explained in the manual, for it states this NOWHERE. At any rate, you are saying that the 2-CHANNEL and MULTI CHANNEL speaker setting will not only affect ANALOG OUT, but also HDMI? Jesus...and this was after I was told and was convinced that these settings ONLY affect analog connections....
