The Bose PAS comes Mono. What does this mean ? Does anyone really know about the PAS architecure ? compared to the regular PA Systems.

The use of stereo outs from a KBD is VERY Important, so how can we compromise in order to send sterio out to the PAS and get all the benefits of panning ??

In order to get sterio from a KBD we NEED to use 2 or more outs. So, using 2 or more outs has anybody tested the PAS for KBD clarity ?

Can some Techies from Bose or anywhere shed some light on the PAS structure because IMO mono and stereo dont apply for the PAS output. Anyway the PAS gives amazing surround and full sound, so mono and stereo dont apply (IMO).
