Yes, Roger has tons of experience professionally with Dolby and practically. However, he does not own or play with a Casablanca, does he? His expertise and wealth of knowledge is astounding, but frankly is enough to scare anyone away from a CBIV-A thinking its a bitch to setup - and its not at all hard to set up!
My apologies to anyone if I am making their life and enjoyment of their new CBIV-A baby anything but what it should be, a joyous event.
K-I-S-S ("Keep It Simple Stupid") - my audio video motto - every time I have strayed from this (too frequently) it almost always ends up being the simplest explanation!
I’m with you on the KISS principle. That’s why bandlimited pink was first adopted by Dolby in 1987 for Pro Logic. Test discs have always posed problems, as it is difficult to get them right even with knowledgeable people involved. I have the AIX, the Goldline, and the Explore Our World DVD from Dolby, and all of them have level errors here and there among their test signals. Discs with no errors, THX Optimizer and Spears&Munsil. There may be others. These are just examples.
It is much simpler, safer, and consistent to use the processor’s internal noise – assuming it is implemented correctly. That means band-limited pink, and that it is post-processed by any room EQ the system supports. Thus far I have seen no objective evidence that the CBIV-A noise is incorrect in the slightest.
Roger, out of curiosity, what is your surround processor these days? When are you going to get a Casablanca or one of its sister companies' Datasat SSP??? Or do you already have one?
I appreciate the generous and cheeky offer to GoFundMyCasblanca.
I’ve been out of the Atmos game for a couple years due to new home/new theater cycle. Now that theater is finished, I’m about to add Atmos again, but it will not be any high end processor since none support PLIIx (not Theta, nor Datasat, nor Lyngdorf, nor Trinnov). Most of my theater use is playing stereo music on 7.1 speakers, and no other upmixer does it for me. So it would be pointless to buy a Theta only for movie playback. The Marantz AV7702 did well enough for Atmos, but I’m curious about Anthem Room Correction so there’s an AVM 60 on the way. It will play through the 7.1 bypass of the SSP-800. Not the most elegant, but it will serve my requirements for 7.1 PLIIx. If the CB adds PLIIx, we'll talk.
