A:AnswerIf I’m not mistaken this sound bar works with its own remote aside from the tv remote but once connected to tv via Bluetooth the tv remote will control the sound bars volume automatically as if you would be controlling the tvs volume.. hope this helps thanks!
A:AnswerHi! The HW-C400 features two ways to connect to an external device: Digital optical audio, and Bluetooth wireless audio technology. If your TV is compatible with one of these two audio connections, you should have no issue connecting the soundbar to your TV. ~Samsung Solutions
