The system can be set up using a wired connection, as per my previous post.
To clarify - the hidden ports are behind sticker covers.
This is NOT the thin paper stickers with the model numbers on.
They are plastic black sticker port covers. You may need to use a knife or sharp edge to lift the sides of the plastic sticker up - the one on the main unit was toughest for me.
Please see the below picture with the port cover on the back of the subwoofer just below the power button & link button.
The cable type is 2 ring aux connections
(Like the ones on your standard 3.5mm headphone cables)
The rears also have these and the main soundbar has the ports labels SW RL and RR (Subwoofer, Rear-left & Rear-right)
(See pics below. The port is on the back near the HDMI ports. It's a hard plastic sticker with 2 screws next to it - you don't need to remove any screws)
The rears are harder to remove because they're recessed but has a tiny hole on the edge to help pry off. I used a very thin bent needle to lift it off (see photos)
