You're also having both the ADA and the QSC do bass management. You're not getting what you paid for from the ADA. And it has nothing to do with whether the ADA or Meridian is better. You'd be better served by a room correction system that does A/D and D/A at at least 96/24. I think the ADA TEQ units may fit the bill, but I'm just going on memory from my discussions with ADA at CEDIA.

Dennis, what's your take?

That ADA TEQ looks pretty serious (and expensive too) what's nice is that it may allow you to JUST do Sub Channels and still do full Room Correction coordinated between the two boxes and only require the 4 Channel TEQ (I don;t know that for sure you'd have to talk to ADA about that). Again I'll say "Don't Mix" Brands (when you don't have to). Splitting Bass Management between two boxes and two brands is just asking for trouble.

Still not a great idea to even resample at 96Khz (I don't know what the TEQ even does for A to D) but at least 96Khz gets into respectable territory if you MUST do all channels. But I would avoid doing all channels if at all possible. And I would not assume TEQ does even 96Khz (it probably does 96Khz or better based on the price and ADA reputation).

You could probably make your QSC work much better too, but I'm not going to get into that remotely on boxes I'm not familiar with. Avsforums can help you on that wink

Thanks Frank and EvdBerg for helping sort this out for Ken.
