... and ALTEC LANSING 251 ( 5.1 speakers system), will they work together ? I mean, will these speakers receive DTS / THX / AC3 signal from the Audigy 2 ZS ? Or will they only be able to handle Dolby Prologic and Dolby Prologic II ? Last question, where the speakers wire will fit in, or where could they be plugged in ? Only in one place or not ? Thank you all in advance !
