If you take a look at the control unit, you'll notice that the audio outputs connect with your satellite speakers. This means that the sounds will be released from whatever is connected to this port e.g. the speakers.
The audio input will be your source of sound such as your mobile phone, PC, or TV. The cable that is used to connect to an audio source is the 3.5mm to RCA cable. We include a 3.5mm to RCA cable in every set.
Take the cable and connect the red and white plug into the control box. The green end will be used to connect to your TV.
While every TV is made differently, you will have to connect the 3.5mm audio cable to your TV's "audio output".
If your TV has the audio output in the form of RCA (red and white ports), then connect this to the 3.5mm port at the front of the control box.
