A:AnswerI am going to guess that you are asking if the bar can be place below a flat screen tv and the answer is yes it is low profile and the sub woofer is wireless so you can pretty much put it any where. I don't know the exact distance that you can put the subwoofer from the sound bar. Yes outside temporary yes.
A:AnswerI have the samsung HW-J450ZA soundbar connected to a Samsung UN65JS8500FXZA TV. Soundbar volume is controlled by either the TV remote, the Cable set top box remote, or the soundbar's remote. No problem.
A:AnswerIt has an optical and hdmi connector. So I guess you can hook it up to any TV, even from another brand.
It will probably doesn't let you use wireless Direct Sound if the tv is not Samsung or doesn't have that feature, but I'm sure you can use it through Optical or Hdmi connectors
A:AnswerNot sure what you mean by sound delay. It sounds like your soundbar may be out of sync. I've experienced that a couple of times. You can either adjust the sync through the remote or turn it off and then on to see if the audio catches up to the video or vice versa. There shouldn't be a delay between the audio from your TV and the soundbar if everything is in sync.
A:AnswerI have Comcast cable, and it will control the volume of the sound bar. You need the sound bar remote to control the "finer" setting of the sound bar.
