Which box do I need to hook up my stereo receiver?
New customer here. Tech installed a 4K wireless box, but didn't know anything about connecting our Harmon Kardon HK 3390 stereo receiver to it. The HK 3390 doesn't have an HDMi or optical option. And the 4K doesn't have an A/V out port. Do I need to request a different box, and which one? Would like to be able to hear Music Choice run through the speakers.
