Can I use this as a dual system, ie wireless and connect to my computer tower?
I am looking for a system that will connect to my computer tower (not wireless) and also let me connect via Bluetooth
Yes, but only one at a time. And if the sounds goes low enough (when using the six input) or stops...movies, games, pause, etc. it will revert to Bluetooth search and look for a Bluetooth signal, then reconnect to the aux input when a strong (loud) enough signal comes through again, or will stay on Bluetooth if a signal is picked up/connected.
