I have a Samsung 4k Smart Tv and an old Technics SA-EX700 Dolby Surround AV-Receiver and I want to be able to get the sound from the TV to play on the sound system connected to the AV control. Since the audio output of the TV is digital (Toslink connection) and the input from of the ampliphier is analog I had to buy a digital to analog audio converter. The converter I bought was this one: And the connections of the Technics SA-EX700 are these: The converter has 3 3.5mm phone jack inputs (1 front left/front right, 1 surroud left/surround right and 1 subwoofer/something else that I don't know). This will lead to 5 RCA jacks. And my question is: where do exactly I connect them in my amp? Should I connect both front and surround cables in the VCR input and the subwoofer one in the subwoofer input? Is that the right way to connect it? Where will the sixth cable be connected?
