I just got the T4 yesterday. It worked for the first few hours. Now the audio controller doesn't work. I lightly tapped the side, and it changes lights when it's tapped, but no response at all to music.

Am I doing something wrong or is it broken?
The fuse is fine.

Are you sure the music is loud enough? It takes a good bass volume to make an audio controlled fixture respond. Try turning up the volume and/or moving the speaker closer to the T4.

Did my suggestion work? Don't ask for help here if you are not going to respond back with a yes or no to our suggestions!

Iguana haha chill bro. In my years as being a mod a no reply is usually yes. ANYBODY can ask questions on the Elation forums.
Sincerely,

Yeah, a bad day and seeking a whipping boy. LOL
