Without knowing more about your TV and its connectors I doubt anyone could give you an exact answer to your question.
If it is coming out of the Concertone's amp AND there is Dolby Encoding in the audio stream, then you will get true surround sound from the speakers. For example a DVD played in the DVD player in the Concertone.
In order to get surround sound from anything else, the line level stereo signal containing the Dolby encoding must pass into the Concertone via one of its line level audio inputs. This means you can't use an earphone output on your TV to feed the audio into the Concertone and get surround sound.
If your TV has L/R line level audio out (RED/WHITE RCA plugs); then you can route the sound output to an unused audio input on the Concertone. If the TV does not have L/R (red/white RCA plugs) all is not lost if there is a digital audio (fiber optic) out socket. They make adapters for about 80 bucks that will convert that fiber optic signal back into line level RCA without losing the Dolby encoding.
Here is a photo of the back of my TV. The two top RCA connectors are L/R audio out and go to AV1 input on the Concertone.
