It's hard to answer your question. You haven't provided enough information for even a reasonable guess. Is there a Meridian dealer nearby? Meridian gear is/was great but it can be very complex to setup and configure.
Also, you might get a better response if you post this in the Home Theater section. Most Meridian systems I have seen are used as part of an HT or multi-media system.
