If the sub has hi-level i/o connections then yes, you connect the speaker cable to the sub then from the sub to the speakers. If it only has a single RCA input then no unless your amp has a dedicated sub output.
You could get a subwoofer that can be connected using a Neutrik connector (e.g. BK and REL) as these have wires that then connect to your amps speaker binding posts.
Yes, so that the sub is basically receiving the full speaker output signal, which is then rolled off using the subs control panel. This is called the high level input.
So you connect the speaker cables from the amp to the high level inputs, then do you connect the high level outputs to the speakers??
I think I know what you are saying - the way I see it is - connect both speakers and sub high level to binding posts on amp - right?
I used to have the XLS200 connected as you have (i.e. with a stereo amp acting as a power amp for the L&R) and would occasionally forget to turn the high level gain down again (when going back to AV mode) but opening the crossover again to let the AV processor do the job. It just means the sub is reproducing the full range as well as the L&R, no harm done as far as I could tell.... it just sounds rubbishThanks again, i've read the manual but nothing is stated about using both connectors simul and which will take precedence or if will cause a problem Will wait for a response from BK or an expert as i don't want to try incase of disaster
