The 8Bus series was designed to eliminate the last barrier between you and audio creativity -- and  capable of sound quality equal to or better than that of $100,000 consoles. 8Bus consoles have recorded more platinum albums and major motion picture soundtracks than any other mixer in their class -- they set the standard for affordable 8-bus consoles.
  Excellent for project studios and digital multitrack recording, when combined with digital multitrack or hard disk recording systems, a Mackie 8
Bus console can create not just major label CDs, but major motion picture soundtracks and network quality commercials.With Mix B, "in-line monitoring" is a breeze. Six aux sends and six aux returns allow you to use all the effects you want. And the 8Bus's complete talkback and phones level controls make communicating with the talent a snap. There's much more:
  When you get right down to it, the 8
Bus series of recording consoles is a value at many times the price. The fact that artists and producers of every shape and size have sworn by them means when you buy an 8Bus you'll be in good company.
