A:AnswerIf you’re using the HDMI ARC connection, turn your tv speakers to either mute or turn the tv sound low. The sound bar is controlled by the HDMI ARC connection.
A:AnswerHi, Joss.
Than you for sharing your inquiry. This soundbar cannot be paired to another one. You could only connect both to the same device using a splitter for RCA cables.

A:AnswerHi, Josh.
Thank you for taking the time to share your inquiry. The Soundbar does not include any parts to attach to another device nor the wall. You can get these parts by checking with official retailers.

A:Answerthere are two ways to hookup the sound bar. if you don't have optical on your television then hook it up with the cables that came with your speaker then you should get a good picture because your TV doesn't require pcm setting.
