Hello
i have an arc, sup and 2 one sl in my TV room. But I can not get them all to connect together? I want to use the 2 sl for back speakers.
when I connect the sub to sl then it disconnects to the arc. When I connect the arc to the sub the sl disconnect from the sub.
hope to get some help 
The Sub and One SLs all connect to the Arc.
