Unfortunately it won't be able to decode a dts signal, as it doesn't have an inbuilt DTS decoder, only Dolby Digital. Your Mico may be able to decode a DTS signal and output it through the 5.1 phono sockets, but this doesn't help you as the Acoustic Solutions package doesn't have an analogue 5.1 input.
Out of interest how good do you find this system with Dolby Digital soundtracks?
I was thinking of buying one for the bedroom.
