From what I understand from reading the Trinnov site the system should work just fine with a 2.1 input as long as the entire array of speakers are active. The Trinnov site says their algorithm works with 2-16 speakers which would seem to indicate that a 2.1 system is at least possible although it would obviously need a different correction matrix. Not sure if there's an advantage to this; I wouldn't think so.

Of course, as has been mentioned in other threads, it's all a matter of implementation. Will the Trinnov Optimizer be available for all inputs or only certain ones?
