The lights on my AudioControl amplifier aren't bouncing up and down, but my system still sounds fantastic. Is the display broken?
AudioControl amplifiers are some of the most powerful and reliable amplifiers on the planet.  For this reason, the lights on the front rarely bounce while being listened to at a normal volume.  Chances are that you're not listening at peak volume (so the lights aren't "dancing".  Given the authoritative power of AudioControl amplifiers, we're sure your ears thank you for listening at moderate levels.
