By connecting the Sync box to a HDMI media device such as streaming stick, set-top box, and gaming console, and attaching the LED strip to the back of your TV, you can make lights sync with the colors and brightness of the TV screen. 

The Sync box reads the video signal directly from the HDMI input, analyzes the entire screen, and instructs lights to mimic the colors on the TV screen. ​

The Sync box also has a built-in microphone that can capture audio playing from any source and make lights change colors and brightness with the music. You may want to place the sync box close to the speakers so it can better detect the audio. (The microphone is only enabled when the Rhythmic mode is running.)
