Would the behringer correct for time? I use an hk3490 as a preamp into a QSC CX404 to "Bi-Amp" my S8's. The HK does not have room correction. Any suggestions for hardware that can do this?
If you are using a pream/processor or receiver without delay, then your only option is professional digital delay units.
Pro delay units usually have multiple functions including delay.
This unit from Lexicon is two channel. If you want more channel then you really do need an AV prepro, or the expense will rally add up.
If it is just two channel the it will do what you want. However I don't see the need for this in a two channel audio home system.
You really have not given us any clue as to what you want. To give intelligent advice we need extreme details of your system and your engineering plans and goals. Your post so far are pretty much useless and you are lucky I did not ignore them.
Without further pertinent engineering details, they will be ignored.
