i'm a IMAX projectionist, no it's just a ALL digital 6 discrete channels. no theater has lossless sound it's either in DTS which most movies are or THX. and i would pick IMAX sound over THX cause IMAX may hav a 6.4 system they r percisely tuned. where as THX has like 11.2 system their just equalized. and then IMAX has a more powerful audio setup. IMAX has 12,000 watts compared to THX 8000 watts. so being in a IMAX theater is like being at a rock concert.
