A Panasonic home theatre system includes an audio-video receiver with connection jacks to hook up components such as a cable box for playback on a TV. If the cable box is a high-definition model, a high definition media interface (HDMI) cable can be used to transmit digital audio and video through a single connection to the Panasonic receiver. If HDMI is not available on the cable box, an RGB component video cable and stereo cable will also work with the Panasonic.
Insert the HDMI plug with the narrow edge turned downward into the HDMI OUT port on an HD cable box. If HDMI is not available, connect the red, green and blue plugs on an RGB video cable to the colour-coded Video OUT jacks on the back of the cable box.
Push the HDMI plug on the other end of the cable into the matching HDMI IN port on the rear of the Panasonic home theatre receiver, or insert the three RGB plugs into the Component Video IN jacks on the receiver.
Connect a stereo cable from the two Audio Out jacks on the cable box to the Audio IN jacks on the Panasonic to provide sound with an RGB video connection, which only transmits picture. The white plug on each cable end connects to the left jacks. Connect the red plug to the right jacks.
Turn on the Panasonic receiver and set the selector knob on the front panel to the name of the jacks for the cable box connection, for example "HDMI 1" or "Component Video."
