I have a Lexicon DC-2 (version 4.0 and fully loaded with the DD, DTS, and THX daughter boards) and a 7.1 speaker system. Looking at the display, I cannot tell if DolbyDigital-EX and DTS-ES encoded soundtracks are being properly decoded. According to the manual, I can get EX and ES decoding while in THX mode, but it makes no mention of any other decoding scheme (DD, DTS, L7, etc.) in this respect. Is there any way to assure EX and ES decoding in at least Logic 7, since that's what I almost always have it set to?
