The warm, natural sound of a vacuum tube is still perhaps one of the most tantalizing sounds any true music fan can experience. With this in mind, Phonic is delighted to introduce you to the Celeus Tube - one of the most unique analog mixers available today. While this amazing analog console features your typical transistor outputs, Phonic engineers have also integrated an independent 12AU7 tube.

Thanks to its user friendly design, the Celeus Tube delivers countless features that even the most novice user can utilize. Users will find built-in Bluetooth audio streaming, USB digital audio recording and playback, and a smartphone charging port. You'll never look at traditional mixing the same again after you experience the Celeus Tube.
