My TV model is 43UF64 , I want to connect the TV audio to my amplifier, how can i connect the TV when it's only have an optical digital audio out and my amplifier does'nt have optical digital audio in, but only RCA jack type L and R?

Asked by: Vic22
You can connect the Optical Digital Audio Output on the ENERGY STAR® Qualified LG 4K UHD Smart LED TV - 43" Class (42.5" Diag), Model # 43UF6400 to an older receiver that only has RCA inputs on it, but you will need to get a Digital/Analog converter that has an Optical Digital Audio input and one end and Analog RCA Stereo Output ports at the other end. The converter converts the digital signal from your TV's optical output into an analog signal that it outputs through the RCA Stereo outputs that you can connect to your receiver...^IFV
