Connection of audio from newer HDTV to older Receiver.


Jun 28, 2016
I have a Samsung 50" Plasma ( and I want to connect it (ie - the audio) to my older receiver, an Adcom GTP 450 Preamp/Tuner ( I've tried using standard RCA red/white cables but it doesn't seem to work. Am I missing something obvious? Thanks.

I should add that I previously had this hookup but with a directv cable box in between the tv and receiver and the audio worked fine. Did the cable box work as some type of converter for the audio and therefore would I need something like this?

I just looked at the pictures that you linked to and you seem to need a TOSLINK cable out of your TV, but your receiver does not support that type of input. You can not hook these two devices together without another device such as a DAC.
