I bought the Bose sound touch sound bar and sub woofer, it has an HDMI in and HDMI out. It uses the arc for T.v's. I also purchased the Ben Q HT2050. How am I supposed to hook up all my other components like ps4 , apple tv, direct tv etc?
Our projectors don’t use Arc unfortunately. In that scenario you would need a multi port input. Most surround sound receivers have that built in. A good quality HDMI hub with an optical out would work for your situation.
