A:AnswerHi Wilson, The soundbar comes with a remote, however when you connect it to a Samsung TV then the TV remote will operate the soundbars volume and power on and off for the majority of Samsung Tv models. ^Jeremy
A:AnswerHi Sheryl, The soundbar is made to connect to a TV and therefore your accessories (Firestick) would need to be in the TV. Whatever the TV is playing for audio could then go through the soundbar. A turntable will not connect to a soundbar. ^Jeremy
A:AnswerHello, your TV will determine how many audio devices it will output to at one time. Typically you can only output to one however. Thanks, ^Scott
