Is the DSB1 soundbar and Omni SB1 bluetooth compatible

I bought the DSB1 soundbar, DSB2 sub woofer and DSB3 rear speakers through DishTV when I had Dish installed. I cannot find any info on the DSB1 soundbar and I am trying to connect blue tooth to my Polk soundbar to make it work with my Amazon Echo Dot which came with my Dish, is this possible? I had to order the blue tooth adapter and I received an Omni blue tooth and it does not see to be the right one. The connector on the back of the soundbar is more of a cube and not a blade type.
