The FF6-2L was designed by Formula Sound to Funktion One specifications.
Funktion-One also has electronics components, like amps and polarity checkers, manufactured to their specifications.
They even had Formula Sound start making Funktion-One-branded DJ mixers, because save "an old Urei, maybe," they didn't think there was one on the market up to the standards of their rigs. If Tony Andrews could, he'd have a hand in every link in the chain: master and cut the vinyl, code his own digital audio file format, design every component in the booth, maybe even set the gain and work the EQ so that DJs couldn't redline. "It's like a series of windows, one behind the other," he said, using his favourite simile for the signal chain at clubs. "You only need one dirty window and you can't see the view any more." But he realizes that all he can do is keep tinkering with the thing he knows best, the one he's committed to professionally and spiritually for more than four decades. "I've just got my whole being tuned into listening to audio. It would be crazy to not keep going with it, if you see what I mean."
As an alternative to Rane, Allen & Heath, Ecler, Bozak or Soundcraft UREI 1603/1605 DJ mixers the Formula Sound FF6-2L is unrivalled and its outstanding audio quality is unsurpassed.
